Rectal atresia or stenosis is an extremely rare anorectal malformation associating a normal anal canal with a stricture or a complete rectal atresia. We describe a case of rectal atresia in a newborn female presenting with an abdominal distension and failure of passing meconium.

Facial nerve aplasia is an extremely rare condition that is usually syndromic, namely, in Moebius syndrome. The occurrence of isolated agenesis of facial nerve is even rarer, with only few cases reported in the literature. We report a case of congenital facial paralysis due to facial nerve aplasia diagnosed on MRI, while no noticeable abnormality was detected on the temporal bone CT.

Originally recognized by Cushing and Bailey, hemangioblastoma is a developmental vascular neoplasm that is predominantly found in the posterior fossa. It is a highly vascularized tumor, with well-differentiated histologic features. Although rare, it remains the most common primary tumor of cerebellum in adults, along with metastases. MRI is the gold standard, allowing a precise characterization of the lesion's features, and its relationship with the surrounding structures. We report the case of a patient with a cerebellar symptomatology, in whom brain MRI raises the diagnosis of hemangioblastoma, which was then confirmed by histopathologic examination.

Cystic meningiomas are very rare tumors of the central nervous system. We report the case of a 62-year-old female how presented headaches resistant to usual analgesics with behavior disorders. Cerebral CT scan showed a right frontal extra-axial tumor with firm and cystic component, brain MRI evoked the diagnosis, surgery removed the entire tumor and histological examination confirmed it. A cystic meningioma should not be omitted from the differential diagnosis of brain tumors with a cystic component and which clinical, radiological, histological and therapeutic features are discussed.

Background. Ogilvie syndrome is a rare postpartum complication. It is characterized by an acute colonic pseudo-obstruction which occurs in the absence of a mechanical cause. Early detection of the diagnosis is essential to avoid cecal perforation. Case report. We report a case of Ogilvie syndrome following caesarean section in a 39-year-old woman (gravida 2, para 2) with a history of secondary infertility 10 years ago due to tubal stenosis and subserous fibroma, which led to the indication for cesarean section in second pregnancy at 39 weeks of gestation. Three days after cesarean section, the patient presented with significant abdominal distension and tenderness, vomiting, weakness, and nausea; an abdominal X-ray showed cecal distension. Abdominal computed tomography scan with intravenous contrast revealed distension of the ascending and transverse colon with air-fluid levels but without transitional mechanical obstruction. The patient was successfully treated. Conclusions. Ogilvie syndrome is a rare but serious complication that should be considered in fit young patients who present with pain, severe abdominal distension and failure to pass flatus after caesarean section.
