Background: Intracranial Ewing’s sarcoma (ES) is a rare entity with <15 cases reported in the literature. It belongs to a family of round-cell neuroectodermally derived tumors bearing many similarities to peripheral primitive neuroectodermal tumor (pPNET). There is currently no established treatment protocol. Reported cases are treated with either surgery alone or surgery with adjuvant chemotherapy and radiation. Case Description: We describe a case of intracranial left frontal ES in a 19-year-old patient who presented with change in behavior. Diagnosis was unclear based on radiological findings on MRI and CT alone. MRI brain with contrast demonstrated a large extra-axial ovoid heterogeneously enhancing left frontal convexity mass. The patient underwent gross total resection with adjuvant chemotherapy and radiation. No local or systemic recurrence was found at 12 months postoperatively. Conclusion: Intracranial ES/pPNET is rare tumor with nonspecific clinical presentation and radiological findings. They are locally invasive. Surgery with adjuvant chemoradiation is the mainstay treatment. Distinction of pPNET and cPNET is important for therapeutic and prognostic purposes.

Foreign body aspiration is relatively infrequent in adults. Airway foreign bodies (AFBs) can be removed by flexible bronchoscopy (FB) or rigid bronchoscopy (RB). We performed a retrospective analysis of FBs performed in our centre over a 25 year period, focusing on the procedures that revealed an AFB during the examination stage. We recorded demographic data, clinical characteristics and radiological and bronchoscopic findings. During the study period, 12,588 FBs were performed in adults. Airway foreign bodies were identified in 32 of these cases, giving a prevalence of 0.25%. The most frequent clinical presentation was cough, sputum and fever. The most frequent radiological findings were alveolar infiltrates and atelectasis. In 94% of cases, AFBs were removed successfully by FB; RB was necessary in only 6% of cases. There were no FB-related complications. The most common AFB location was the right bronchial tree (69%). We classified AFBs as organic (85%: animal 57%; vegetable 28%), inorganic (6%) and iatrogenic (9%). Bronchial infection occurred in 51% of cases, and Actinomyces spp. was the most common causal microorganism. In conclusion, AFBs are a rare entity with nonspecific clinical presentation, most AFBs were organic, and FB is a safe and effective method for AFB removal.

Chronic intussusception is a relatively uncommon disease most commonly observed in older children. Waugh’s syndrome represents a rare entity characterized by intestinal malrotation and acute intussusception. We report a very unusual case of intestinal malrotation associated with chronic intussusception. Clinical presentation, radiological findings, and managing of this association are discussed in the light of the available literature.

Abstract Cysticercal brain abscess is a rare entity with the clinical presentation and radiological findings closely mimicking a pyogenic abscess. We report three cases of cysticercal abscess presenting as solitary lesion in the brain with radiological appearance like an abscess. All the patients underwent excision of the lesion with histopathological diagnosis of cysticercal brain abscess. The clinical outcome was satisfactory after surgical excision. Cysticercal abscess, though rare, should be considered as a differential diagnosis of a solitary rim-enhancing lesion, mainly if the patients belong to the endemic zone of neurocysticercosis. Surgical excision with or without a short course of the anti-parasitic agent is the treatment of choice.

Abstract OBJECTIVE AND IMPORTANCE: Intramedullary melanotic schwannomas are very rare lesions; only four cases have been reported previously. We describe a patient with an intramedullary melanotic schwannoma that had a more aggressive course than those reported in the literature, and we review the theories regarding the cause of these lesions. CLINICAL PRESENTATION: A 35-year-old man presented with neck stiffness and paraesthesia extending down his right arm upon neck extension. A magnetic resonance imaging scan revealed an intramedullary lesion extending from C4 to C5. INTERVENTION: Gross total resection of the mass was performed, and pathological characteristics were consistent with a melanotic schwannoma. Two years after resection the tumor recurred, and the patient was treated with radiation therapy. The tumor progressed 2 years after radiotherapy, and at repeat resection, multiple pigmented foci were present on the surface of the spinal cord and dura consistent with metastatic seeding. CONCLUSION: In a patient with intramedullary melanotic schwannoma with an unusually aggressive course, careful follow-up may be essential.

Meningiomas are uncommon tumors in children and either more rarely encountered in the pineal region. We report two cases of meningioma of the pineal region in children. One of these cases was a five years-old girl and the other a one year-old boy. No specific clinical presentation or tomographic examinations findings was identified before treatment, suggestive of a diagnosis of menigioma. The clinical and laboratory features were very similar to the most common tumors of the pineal region. Prior to the surgery, the histology of these tumors was not suspected. Both patients underwent direct surgery and complete removal was achieved by a suboccipital transtentorial approach. The tumors originated from velum interpositum in both cases. At the follow up, one case presented with recurrence six years later, and she underwent a reoperation with total resection without morbidity. Long-term follow up presented no other recurrences.

Rare Congenital Abnormality

PURPOSE: To illustrate the radiological findings and review the current literature concerning a rare congenital abnormality of the posterior arch of the atlas. CASE REPORT: An adult female without neurological symptoms presented with an absent posterior arch of the atlas, examined with plain films and helical computerized tomography. Complete agenesis of the posterior arch of the atlas is a rare entity that can be easily identified by means of plain films. Although it is generally asymptomatic, atlantoaxial instability and neurological deficits may occur because of structural instability. Computerized tomography provides a means of assessing the extent of this abnormality and can help evaluate the integrity of neural structures. Although considered to be rare entities, defects of the posterior arch of the atlas may be discovered as incidental asymptomatic findings in routine cervical radiographs. Familiarity with this abnormality may aid medical professionals in the correct management of these cases.

The Relationship

Abstract Background The spleen contains immune cells and exhibits a pattern of infarction different from other organs; as such, splenic infarction (SI) may provide important clues to infection. However, the nature of the relationship between SI and infectious disease(s) is not well understood. Accordingly, this retrospective study investigated the relationship between SI and infection. Methods Hospital records of patients with SI, who visited Inha University Hospital (Incheon, Republic of Korea) between January 2008 and December 2018, were reviewed. Patient data regarding clinical presentation, causative pathogens, risk factors, and radiological findings were collected and analyzed.Results Of 353 patients with SI, 101 with infectious conditions were enrolled in this study, and their data were analyzed to identify associations between SI and infection. Ten patients were diagnosed with infective endocarditis (IE), and 26 exhibited bacteremia without IE. Twenty-seven patients experienced systemic infection due to miscellaneous causes (negative result on conventional automated blood culture), including the following intracellular organisms: parasites (malaria [n =12], babesiosis [n =1]); bacteria (scrub typhus [n =5]); viruses (Epstein–Barr [n =1], cytomegalovirus [n =1]); and unidentified pathogen[s] (n =7). Splenomegaly was more common among patients with miscellaneous systemic infection; infarction involving other organs was rare. Thirty-eight patients had localized infections (e.g., respiratory, intra-abdominal, or skin and soft tissue infection), and most (35 of 38) had other risk factors for SI. Conclusions In this study, various infectious conditions were found to be associated with SI, and intracellular organisms were the most common causative pathogens. Further studies are needed to examine other possible etiologies and the underlying pathophysiological mechanisms.

Ingested foreign bodies usually pass uneventfully through the gastrointestinal tract but few of them can cause symptoms. They can get stuck at acute angulations or narrow part of intestine and can perforate leading to localized to generalized peritonitis, collection or abscess formation. We describe a case of 59 year old gentleman who presented with pain in right iliac fossa with fever and a hard, tender lump. Initial investigation revealed a mass in right iliac fossa adherent to anterior abdominal was in right iliac fossa region with a foreign body inside. Patient was managed with exploratory laparotomy, removal of a fish bone from cacecum and limited right hemicolectomy. Fishbone perforation of caecum is a rare entity. Careful corroboration between patient’s presentation and radiological findings with a high index of suspicion is needed for pre-operative diagnosis.
