Abstract Objective: Mediastinal schwannomas sometimes can be confused with other neoplasms in the initial radiological studies, especially when there is a history of cancer in another site and that require a more accurate analysis by computed tomography (CT) or even magnetic resonance (MRI). Our study was aimed to perform a retrospective analysis of the clinical and imaging features in a series of patients with mediastinal schwannomas that were confirmed by histology and immunohistochemistry.Results: We found eight patients, five man and three women with an average age of 51 years. The main signs and symptoms at time of diagnosis were chest pain, dyspnea, cough and dysphagia. CT showed that the tumor was located in the posterior compartment of the chest in 7/8 cases. Tumors >10 cm were more heterogeneous and showed cystic changes. All cases underwent posterolateral thoracotomy and radiological follow-up showed no evidence of recurrence. Histological analysis was the gold standard to confirm diagnosis in addition to at least one neurogenic IHC marker. In conclusion, mediastinal schwannomas are benign encapsulated tumors. By CT, schwannomas >10 cm showed cystic degeneration more frequently. Posterolateral thoracotomy allows complete resection and is considered the surgical approach of choice.

Abstract Objective Mediastinal schwannomas are sometimes confused with other neoplasms during initial radiological studies, especially when there is a history of cancer in another area. In these cases, a more accurate analysis using computed tomography (CT) or even magnetic resonance (MRI) is required. Our study aimed to perform a retrospective analysis of the clinical and imaging features for a series of patients with mediastinal schwannomas that were confirmed by histology and immunohistochemistry. Results We found eight patients, five men and three women, with an average age of 51 years for this study. The main signs and symptoms at diagnosis were chest pain, dyspnea, cough, and dysphagia. CT showed that the tumor was located in the posterior compartment of the chest in 7/8 cases. Tumors > 10 cm were more heterogeneous and showed cystic changes. All patients underwent posterolateral thoracotomy, and radiological follow-up showed no evidence of recurrence. Histological analysis was considered the gold standard to confirm diagnosis, along with at least one neurogenic IHC marker. In conclusion, mediastinal schwannomas are benign encapsulated tumors. According to CT, schwannomas > 10 cm show cystic degeneration more frequently. Posterolateral thoracotomy allows complete resection and is considered the surgical approach of choice.

Rathke's Cleft

Rathke's cleft cysts (RCCs) are benign cysts typically located in the sellar or suprasellar region; ectopic isolated lesions are extremely rare. The authors describe the case of a 25-year-old man with a giant symptomatic RCC arising primarily at the cerebellopontine angle (CPA), only the second case reported thus far. The patient presented with a 2-year history of right hearing impairment and tinnitus accompanied by vertigo and headache and a 2-week history of right facial numbness. Subsequently, he underwent total cyst removal via retrosigmoid craniotomy with a good recovery. He experienced no recurrence during a 64-month follow-up period. The possible pathogenesis, differential diagnosis, and surgical treatment of such cysts are discussed in this article. Isolated ectopic RCCs can arise from the ectopic migration of Rathke's pouch cells during the embryonic period. It is still difficult to distinguish ectopic RCCs from other cystic lesions of the CPA given the lack of specific imaging features. Aggressive resection of the cyst wall is not recommended, except when lesions do not closely adhere to adjacent structures.

Abstract Background Rhino-Orbital-Cerebral Mucormycosis (ROCM) is an important infectious disease encountered in huge number in this recent post-covid 19 era. An alteration in defence immune system during covid-19 illness, in the presence of uncontrolled hyperglycaemia has led to the new epidemic of ROCM especially in developing nations like India. Method This case series of thirteen patients illustrates the various clinical presentation, laboratorical parameters, imaging features and outcome of patients of ROCM admitted in a tertiary care hospital in Northern India. Result In our case series, a total of 13 newly diagnosed cases of Rhino-Orbital-Cerebral Mucormycosis were studied. History of covid-19 illness was observed in 7 cases (53.8%), use of steroid during Covid-19 illness was seen in 5 cases (38.5%), oxygen therapy was given in 4 cases (30.8%). Co-morbid state in the form of diabetes mellitus was present in 12 cases (92.3%) with mean duration 16.69 months with an important finding of 6 cases (46.2%) having new-onset diabetes; hypertension in present in 3 cases (23.1%). Magnetic resonance imaging of paranasal sinuses showed involvement of multiple sinuses in all the 13 cases(100%), including maxillary and ethmoidal sinuses, with frontal in 12 cases (92.3%), sphenoidal in 11 cases (84.6%), symmetric in 9 cases (69.2%), mastoiditis in 4 cases (30.8%), maxillary space involvement in 4 cases (30.8%), palatal involvement in 1 case (7.7%). Multi-speciality approach treatment was given in the liposomal amphotericin B therapy in all the patients along with thorough endo-nasal debridement done in all cases, transcutaneous retrobulbar amphotericin B in 6 cases (46.2%) with exenteration done in 7 patients (53.9%). At 3 months of follow-up, there was substantial clinical improvement in all the cases. Conclusion There should be definite emphasis on high suspicion of mucor clinically for early diagnosis and aggressive management at initial state of diagnosis for better outcome. The need for sustained proper glycemic control during covid 19 era along with judicious use of steroid and public awareness for early symptoms and manifestations of mucor can curb the magnitude of such potentially opportunistic epidemic to a substantial rate. The longer the infection remains undetected, the greater the devastation ROCM can impose, of which blindness is an important hazard.

CONTEXT: Despite the absence of symptoms in the majority of patients carrying lead bullet fragments in their bodies, there needs to be an awareness of the possible signs and symptoms of lead intoxication when bullets are lodged in large joints like knees, hips and shoulders. Such patients merit closer follow-up, and even surgical procedure for removing the fragments. OBJECTIVE: To describe a patient who developed clinical lead intoxication several years after a gunshot wound. DESIGN: Case report. CASE REPORT: A single white 23-year-old male, regular job as a bricklayer, with a history of chronic alcohol abuse, showed up at the emergency department complaining of abdominal pain with colic, weakness, vomiting and diarrhea with black feces. All the symptoms had a duration of two to three weeks, and had been recurrent for the last two years, with calming during interval periods of two to three weeks. Abdominal radiograms showed a bullet lodged in the left hip, with a neat bursogram of the whole synovial capsule. A course of chelating treatment using calcium versenate (EDTACaNa2) intravenously was started. After the chelation therapy the patient had recurrence of his symptoms and a radical solution for the chronic mobilization of lead was considered. A hip arthroplasty procedure was performed, leading to complete substitution of the left hip.

A six-year-old intact male Chihuahua dog was referred for vomiting, diarrhoea and weight loss. Ultrasonographic (US) and computed tomographic examination revealed a focal thickening in the jejunum, with no signs of gross metastatic disease. Histology and immunohistochemistry performed after surgical resection revealed a presumed large granular lymphocytic lymphoma. Treatment with chlorambucil was started, and no signs of recurrence were noticed at serial US follow-up for the following months. Six months after surgery, several lesions were seen in the ventrolateral aspect of the peritoneal cavity both on ultrasonography and CT, and cytology confirmed the suspicion of peritoneal lymphomatosis.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Acute Pulmonary embolism(PE)is a common and potentially fatal medical condition.In contemporary adult population,PE is associated with increased long-term mortality. Purpose Identify predictors of long-term all-cause mortality in patients(pts)admitted due to pulmonary embolism. Methods Retrospective single-center study of hospitalized pts with acute PE between 2015 and 2018.We evaluated comorbidities, admission(AD)presentation such as vitals(with hypotension defined as systolic blood pressure(SBP)<90mmHg,and tachycardia as >100ppm),lab analyses during in-hospital period,imaging features. Mortality(long-term >3months)was also assessed using national registry of citizens.We performed uni and multivariate analysis to compare clinical characteristics of pts who died and who survived,using Cox regression and Kaplan-Meier methods.For the predictor age we assessed discrimination power and defined the best cut-off using area under the ROC curve(AUC)method. Results From 2015 to 2018,182 pts were admitted with diagnosis of pulmonary embolism,60% female with a mean age of 74 ± 13years old.Seventy-one(39%)pts died after a median follow-up of 26[10-41]months.Pts who died were older(80 ± 8 vs71 ± 14,p < 0.001).The best cut-off value of age to predict mortality with 70%sensitivity and 61%specificity was 77years old(AUC 0.703;CI95% 0.63-0.78).Pts who died had more frequently history of neoplasia (21%vs 9%,p = 0.009).The remaining comorbidities were similar in both groups.Pts who did not survive were more frequently hypotensive(28% vs 13%, p = 0.008),had higher creatinine(1.1[0.8-1.4] vs 1.0[0.8-1.2], p = 0.002), lactate(2.3[1.8-2.8]vs 1.8[1.5-2.0],p = 0.007)and NT-proBNP(4694[1498-12300]vs2070[492-6660], p < 0.001)at AD.Maximum troponin I (0.176[0.037-0.727]vs0.126[0.050-0.365]ng/mL,p = 0.012) was also higher than in pts who survived. After adjusting for history of neoplasia,ADcreatinine and maximum troponin I,we found that age (HR1.057;95%CI 1.01-1.11,p = 0.021),AD SBP < 90(HR 2.215;95%CI 1.03-4.76,p = 0.041),lactate(HR 1.17;95%CI 1.01-1.36,p = 0.035)and NT-proBNP(HR 1.510;95%CI 1.250-1.780,p < 0.001)were independent predictors of all-cause mortality. Conclusion In our cohort,the long-term all-cause mortality was 39%over a median  follow-up of 26[10-41]months.In patients with pulmonary embolism,aside from already identified age(especially when ≥70 years old)and NT-proBNP,lactate should also be considered when evaluating long-term prognosis. Furthermore,hypotension at admission increases by 2fold long-term mortality in patients who suffered acute PE.

Abstract Objectives To retrospectively analyze the most common imaging features on CT at baseline and as they evolve with time as the disease progresses or resolves in a cohort of patients affected with 2019 coronal virus disease (COVID-19) pneumonia in Zhuhai, China.Methods We evaluated 38 patients with COVID-19 in the authors’ institution from Jan 1 to Jan 31, 2020. Cases were confirmed by real-time RT-PCR and were analyzed for epidemiological, demographic, clinical, and radiological features. Outcomes were followed up until Feb 18, 2020. Results 38 initial scans and 62 follow-up scans were obtained. 28 (74%) patients had the history of travel to or residence in Hubei Province of China in 14 days prior to the illness onset. Common findings included ground-glass opacification (GGO), sometimes mixed with consolidation, and interlobular septal and intralobular interstitial thickening. Follow-up imaging often demonstrated peripheral GGO and consolidations spreading to the remainder of the lungs and the increasing consolidative component reflecting the progression of the disease. 8 patients (21%) whose swabs or serum were positive for COVID-19 had no imaging findings on CT throughout the disease course. After treatment the serum and sputum tests became negative for COVID-19 in 32(84%) cases. 28(74%) patients were discharged and three (8%) of them were transferred to the Observation Ward, while seven (18%) patients were kept in Isolation Ward. Conclusion The commonest pattern observed was GGO alone or GGO mixed with consolidation predominantly in lower and peripheral lungs. The follow-up CT scan is crucial for the diagnosis and evaluation of the disease process.

Uterine leiomyomas are one of the most common entities encountered in routine gynaecological practice; however, the giant uterine myomas are very rare and can often create a diagnostic dilemma and therapeutic challenge owing to their size, non-specific clinical presentation and degenerations. Here, in this article we review the literature on giant uterine leiomyomas and report one such case in a 38-year-old woman who presented with the complaints of vague abdominal lump, enlargement of abdomen, dysmenorrhea, lower abdominal and pelvic pain since last 2 years and a 6-month history of increased frequency of micturation. Physical examination and radiological investigations suggested a giant abdominopelvic mass, probably a uterine or an ovarian malignancy. An exploratory laparotomy was performed followed by total hysterectomy. Grossly, the specimen was a 15.2 kg uterine leiomyoma measuring 18x18x13 cm in size. Histologically, the benign leiomyoma showed cystic degeneration. The patient’s post-operative and follow-up period was uneventful.
