AimsTo investigate the clinical and imaging features of primary and recurrent lacrimal gland pleomorphic adenoma (LGPA), as well as lacrimal gland malignant epithelial tumours (LGMET).MethodsRetrospective comparative case series from September 2000 to September 2016 in a single tertiary institution. Medical records of cases with histopathologically proven primary LGPA (PLGPA), recurrent LGPA (RLGPA) and LGMET were reviewed.ResultsSixty-four patients with LGPA (55 primary and nine recurrent) and 36 patients with LGMET underwent surgical excision in the study period. There was no significant difference in terms of age, gender or laterality. In terms of symptom duration, that of LGMET (7.1 months) was significantly shorter than PLGPA (23.9 months), which in turn was significantly shorter than RLGPA (127.1 months). Proptosis was the most common presenting symptom among all three groups. On CT, LGMET and RLGPA were significantly more likely to have ill-defined margins (p<0.001) and be heterogeneous (p<0.001) than PLGPA. RLGPAs (56%) were significantly more likely to have calcification than LGMET (34%), which in turn was more likely to have calcification than PLGPA (13%); LGMET (40%) and RLGPA (33%) were significantly more likely to have bony invasion than PLGPA (2.2%). On MRI, LGMETs (55%) were significantly more likely to have a tail or wedge sign indicating infiltration into the posterior orbit than PLGPA (0%) or RLGPA (0%).ConclusionOur study adds important information regarding differentiating clinical and radiological features between malignant and benign epithelial lacrimal gland tumours that would aid in their management.

Pleomorphic adenoma is the most common tumor of the benign salivary gland neoplasms, the submandibular gland is the second most common site of PA after the parotid gland. Authors present 3 series case of pleomorphic adenoma in submandibular salivary gland in institution which were admitted in institution within a month interval. Fine needle aspiration cytology (FNAC) of all 3 cases proved to be benign lesion arising from submandibular salivary gland. All 3 cases underwent excision in to and the postoperative period was uneventful. DT removed on 3rd POD and discharged in POD 10. Biopsy report proved to be pleomorphic adenoma in all cases. past studies showed pleomorphic adenoma most commonly occurs in the parotid gland and its occurrence in the submandibular salivary gland is uncommon. Also, age occurrence involves 30s-50s and is more common in females. But all this case was male and occurred in older age group. Early intervention with surgical excision in toto after definite confirmation with FNAC is the treatment of choice in preventing its malignant transformation.

Cerebrospinal Fluid Leaks

Abstract Objectives The main purpose of this article is to investigate the prevalence and features of posterior fossa defects (PFD) in spontaneous cerebrospinal fluid leaks (sCSFL). Design Retrospective case series. Setting Tertiary skull base center. Participants Consecutive adults undergoing lateral skull base repair of sCSFL between 2003 and 2018. Main Outcome Measures The following data were collected: demographics, comorbidities, radiology and intraoperative findings, and surgical outcomes including complications and need for revision surgery or shunt placement. Patients with incomplete data or leaks following skull base surgery, trauma, or chronic ear disease were excluded. Results Seventy-one patients (74% female, mean age 56.39 ± 11.50 years) underwent repair of spontaneous lateral skull base leaks. Eight ears (7 patients, 11.1%) had leaks involving the posterior fossa plate in addition to defects of the tegmen mastoideum (50%), tegmen tympani (25%), or both (25%). Patients with PFDs more often had bilateral tegmen thinning on imaging (75%, odds ratio [OR]: 10.71, 95% confidence interval [CI]: 2.20–54.35, p = 0.005) and symptomatic bilateral leaks (OR: 9.67, 95% CI: 2.22–40.17, p = 0.01. All PFD patients had arachnoid granulations adjacent to ipsilateral mastoid cell opacification. However, this finding was often subtle and rarely included on the radiology report. There was no significant difference in body mass index, age, presenting complaints, or operative success between the PFD and isolated tegmen defect sCSFL cohorts. Conclusions The posterior fossa is an uncommon location for sCSFL. Careful review of preoperative imaging is often suggestive and can inform surgical approach. PFD patients are similar to those with isolated tegmen-based defects in presentation, comorbidities, and outcomes.

Background The extent of surgery required in the management of pediatric non-medial subperiosteal orbital abscess (SPOA) due to medically refractory complicated acute sinusitis is unknown. Objectives The primary objective is to compare operative outcomes of children treated with combined endoscopic sinus surgery (ESS) and external orbital drainage (EOD) versus those treated with EOD alone. Methods Retrospective case series from a tertiary children’s hospital analyzing outcomes in children requiring surgical management for acute sinusitis complicated by non-medial SPOA between November 2007 and September 2019. Results Sixteen children with a mean age of 9.4 years (95% CI: 7.3–11.4) met inclusion. Eleven (68.8%) underwent combined EOD and ESS, while five (31.2%) underwent EOD alone. Groups were similar in age, symptom duration, white blood cell count, C-reactive protein level, intraocular pressure, Lund-Mackay score, and abscess volume. There was no significant difference in median length of stay between patients treated with a combined approach versus those treated by EOD alone. Cultures identified non-beta-hemolytic Streptococcus species in 56.3% of patients, with Streptococcus intermedius representing the most common organism in 37.5%. In one case, ESS identified a pathogen not acquired via concomitant EOD, which did influence management. No child required a subsequent surgical procedure and there were no operative complications. Conclusions The addition of ESS in the management of pediatric non-medial SPOA was not associated with a statistically different duration of hospitalization. Cultures from concomitant ESS rarely aided in diagnosis or antibiotic therapy. Further study should delineate the indications for ESS in these cases.

AIM: To monitor the prognosis of patients with lacrimal gland pleomorphic adenoma (LGPA) following surgical resection within the past 10y. The factors affecting patient prognosis are analyzed and the experience of surgical treatment is summarized. METHODS: In this retrospective, comparative case series, clinical records from 109 cases of LGPA treated chiefly at the same institution between November 2009 and May 2019 were reviewed. All 109 patients underwent surgery, histopathological examination, and imaging examination. For patients who underwent surgery for the first time, LGPA could be resected completely, including tumor and capsule tissues, using a surgical approach via the eyebrow arch or double eyelid crease. RESULTS: The ratio of males to females was 1:1.60, the ages ranged from 19 to 74 years old with a mean age of 43.64±13.07 years old, and the ratio of left to right eyes was 1:1.37. A total of 109 patients underwent surgical excision and five of these received radiotherapy after malignant transformation. Of these patients, 15 were lost to follow up within the April 1, 2020 deadline and 1 was diagnosed as a recurring pathology. The 5-year recurrence rate for 86 patients who underwent initial surgery was 7.27%. Single factor analysis revealed that the course of disease, bone destruction, invasion of surrounding tissues, tumor size, capsule integrity, and expression of Ki-67 were statistically significant (P<0.05). Binomial Logistic regression analysis showed that capsule integrity was a risk factor influencing recurrence (P=0.008). CONCLUSION: LGPA has a risk of recurrence and potential for malignant transformation. Complete removal of the tumor and capsule in the initial surgery is a key factor in preventing recurrence.

Background It is essential to distinguish malignant from benign epithelial neoplasms in the lacrimal gland for different treatment options and prognosis. Purpose To retrospectively assess the performance of magnetic resonance imaging (MRI)-based radiomics features in the differentiation of benign and malignant epithelial neoplasms in the lacrimal gland. Material and Methods Seventy-six consecutive patients with histopathology-proven epithelial neoplasms of the lacrimal gland were enrolled in the study, including 41 benign and 35 malignant neoplasms. Radiomics features were extracted from T2-weighted and post-contrast T1-weighted imaging. The least absolute shrinkage and selection operator method was used to select imaging features and reduce data dimension to discriminate malignant from benign neoplasms in the lacrimal gland. Diagnostic performance of the radiomics model was assessed by receive operation characteristic (ROC) curve and compared with that of radiologists. Results Four quantitative image features including inverse difference moment normalized (IDMN), mean deviation (MD), standard deviation (SD), and long-run emphasis (LRE) were selected to distinguish malignant from benign epithelial neoplasms in the lacrimal gland. Area under the curve (AUC) of these four features were 0.88, 086, 0.88, and 0.86, respectively, with 0.93 for the combination model. The model identified malignant epithelial neoplasms from benign group with 89% sensitivity, 93% specificity, and 89% accuracy. There was a significant difference in the diagnostic performance of radiomics model and the radiologists, with AUC of 0.70 for radiologists. The diagnostic performance of radiomics is superior to that of radiologists. Conclusion MRI-based radiomics analysis has potential for differentiation of benign and malignant epithelial neoplasms in the lacrimal gland.

Background: Pleomorphic adenomas are benign salivary gland tumors predominantly arising from the superficial lobe of the parotid gland and rarely from the small salivary glands located at various locations including parotid, lacrimal duct, lip, floor of the mouth etc. Surgical excision of the tumor mass is the treatment of choice with utmost care taken to preserve the facial nerve in cases involving the parotid gland. Case details: This case series highlights three consecutive cases of pleomorphic adenoma arising from three different locations. Conclusion: Pleomorphic adenoma is the commonest salivary gland tumor characterized by diverse histomorphological features and can occur at any site where salivary tissue is present. Careful histopathological analysis should be done in all tumors arising especially in the head and neck region.

Abstract Background. Over the past years, eosinophil infiltration involving the gastrointestinal tract and pancreas leading to eosinophilic pancreatitis, eosinophilic gastroenteritis and hypereosinophilic syndrome has been reported in the literature. We aimed to analyze and compare the features involving patients with eosinophilic pancreatitis and pancreatitis associated with eosinophilic gastroenteritis and to determine if there is a connection between the two disorders or if they in fact meet the diagnostic criteria for hypereosinophilic syndrome. Material and methods. The following search was performed in March 2019 on PubMed (MEDLINE) database using the medical terms “pancreatitis”, “eosinophilic pancreatitis”, “eosinophilic gastroenteritis” and “hypereosinophilic syndrome”. Results. The search revealed 119 publications from 1970 onwards. A total of 83 papers were excluded, and the remaining 36 publications, consisting in case reports and case series, were analyzed. From 45 patients, 20 subjects with eosinophilic gastroenteritis developed pancreatitis, 20/45 had eosinophilic pancreatitis, and 5/45 hypereosinophilic syndrome involving the pancreas. There was no significant difference regarding clinical, laboratory and imaging features between the three groups, despite the multiple theories that explain the association of pancreatic and gastrointestinal eosinophilic infiltration. Although there was a strong resemblance between the three groups, histological evidence of eosinophilic gastrointestinal infiltration guided the treatment towards a less invasive way, while subjects with eosinophilic pancreatitis underwent pancreatic surgery to exclude potentially malignant lesions. Conclusion. Although there are various theories that explain pancreatitis development in patients with eosinophilic gastroenteritis, hypereosinophilia diagnostic work-up should be taken into account in all patients with high number of blood eosinophils, even in those with eosinophilic pancreatitis in order to establish the diagnosis using a minimally invasive approach and to apply an adequate treatment.

AimsTo review the distribution of pathology in extraocular muscle (EOM) biopsies performed at a tertiary orbital centre, identify clinical and imaging features which are associated with benign or malignant diseases and indicate when biopsy is necessary for EOM enlargement.MethodsRetrospective case series including 93 patients with EOM enlargement who underwent an EOM biopsy. Clinical, radiological and histopathological information was recorded from the medical records. Statistical analysis was used to compare variables between patients with malignant and benign biopsies.ResultsThe median age of subjects was 61.1 years. Forty-eight cases (52%) were benign and 45 (48%) were malignant. Those with malignant pathology were significantly older (P<0.0001). Males were more likely affected by a benign disease and females by a malignancy (P=0.029). A history of malignancy (P<0.0001) and diplopia (P=0.029) were significant factors in predicting a malignancy. Pain (P=0.005) and eyelid erythema (P=0.001) were more likely in benign conditions. Idiopathic orbital inflammation was the most common benign diagnosis and lymphoma the most common malignancy.ConclusionsBiopsy is warranted in those with an atypical presentation of EOM enlargement or suspected of having a malignancy. Some features such as age, gender, pain, diplopia, history of malignancy and eyelid erythema may help indicate a particular diagnosis; however, clinical features and imaging findings are often not pathognomonic of each disease.

Idiopathic Anaphylaxis

Background: Undifferentiated somatoform (US) idiopathic anaphylaxis (IA) is considered a psychogenic disorder characterized by a lack of observable physical findings and poor response to treatment. Although failure to diagnose true anaphylaxis can have disastrous consequences, identification of US-IA is crucial to limit unnecessary expenses and use of health care resources. Objective: To better define the presentation and understand the potential relationship between US-IA and underlying psychiatric comorbidities. Methods: We retrospectively reviewed 110 visits by 107 patients to our institution for evaluation and management of anaphylaxis over a 1-year period. The patients were classified as having either criteria positive (CP) or criteria negative (CN) anaphylaxis based on whether they met Second National Institute of Allergy and Infectious Disease/Food Allergy and Anaphylaxis Network Symposium criteria for the clinical diagnosis of anaphylaxis. Patient characteristics, including objective and subjective signs and symptoms, and the presence of psychiatric diagnoses were collected and analyzed. Statistical significance was assessed by using the Fisher exact test. A literature review of US-IA and other psychogenic forms of anaphylaxis was performed. Results: Patients with CP anaphylaxis were more likely to present with hypotension, wheezing, urticaria, and vomiting than were patients with CN anaphylaxis. The patients with CN anaphylaxis were more likely to present with subjective symptoms of sensory throat tightness or swelling compared with patients with CP anaphylaxis. No significant difference was detected in the prevalence of psychiatric conditions between the two groups. Conclusion: Patients who met previously established diagnostic criteria for anaphylaxis were more likely to present with objective physical findings than those who did not meet criteria for true anaphylaxis. CN patients who presented for treatment of anaphylaxis were more likely to present with subjective symptoms. Formal diagnostic criteria should be used by clinicians when evaluating patients with suspected anaphylaxis.

OBJECTIVEIntraoperative neuromonitoring (IOM), particularly of somatosensory-evoked potentials (SSEPs) and motor-evoked potentials (MEPs), evolved as standard of care in a variety of neurosurgical procedures. Case series report a positive impact of IOM for elective microsurgical clipping of unruptured intracranial aneurysms (ECUIA), whereas systematic evaluation of its predictive value is lacking. Therefore, the authors analyzed the neurological outcome of patients undergoing ECUIA before and after IOM introduction to this procedure.METHODSThe dates of inclusion in the study were 2007–2014. In this period, ECUIA procedures before (n = 136, NIOM-group; 2007–2010) and after introduction of IOM (n = 138, IOM-group; 2011–2014) were included. The cutoff value for SSEP/MEP abnormality was chosen as an amplitude reduction ≥ 50%. SSEP/MEP changes were correlated with neurological outcome. IOM-undetectable deficits (bulbar, vision, ataxia) were not included in risk stratification.RESULTSThere was no significant difference in sex distribution, follow-up period, subarachnoid hemorrhage risk factors, aneurysm diameter, complexity, and location. Age was higher in the IOM-group (57 vs 54 years, p = 0.012). In the IOM group, there were 18 new postoperative deficits (13.0%, 5.8% permanent), 9 hemisyndromes, 2 comas, 4 bulbar symptoms, and 3 visual deficits. In the NIOM group there were 18 new deficits (13.2%; 7.3% permanent, including 7 hemisyndromes). The groups did not significantly differ in the number or nature of postoperative deficits, nor in their recovery rate. In the IOM group, SSEPs and MEPs were available in 99% of cases. Significant changes were noted in 18 cases, 4 of which exhibited postoperative hemisyndrome, and 1 suffered from prolonged comatose state (5 true-positive cases). Twelve patients showed no new detectable deficits (false positives), however 2 of these cases showed asymptomatic infarction. Five patients with new hemisyndrome and 1 comatose patient did not show significant SSEP/MEP alterations (false negatives). Overall sensitivity of SSEP/MEP monitoring was 45.5%, specificity 89.8%, positive predictive value 27.8%, and negative predictive value 95.0%.CONCLUSIONSThe assumed positive impact of introducing SSEP/MEP monitoring on overall neurological outcome in ECUIA did not reach significance. This study suggests that from a medicolegal point of view, IOM is not stringently required in all neurovascular procedures. However, future studies should carefully address high-risk patients with complex procedures who might benefit more clearly from IOM than others.
