A rare complication of chronic subdural hematoma evacuation: brain stem hemorrhage: Case report

Chronic subdural hematoma (CSDH), which commonly affects the elderly, is one of the most frequent, but also benign neurosurgical pathologies. Burr hole drainage is the standard surgical modality for evacuation of a CSDH. This technique is known to be safe, with low morbidity and mortality rates. However, postoperative complications have occasionally been reported. We report the case of a 70-year-old man who presented a fatal brain stem hemorrhage after burr-hole drainage for unilateral chronic subdural hematoma. Asymmetrical and rapid decompression were thought to be leading to vascular disruption or sudden increase in cerebral blood flow, was probably responsible for the secondary brain stem bleeding. Therefore, a slow rate of evacuation of chronic subdural hematomas, as well as rigorous postoperative reanimation, are recommended in order to prevent serious complications

Aseptic ascites and chemical meningitis following ventriculoperitoneal shunting for craniopharyngioma: A first case report

Abstract We report the case of a 4‐year‐old boy who had a ventriculoperitoneal shunt due to hydrocephalus related to a cystic craniopharyngioma. Postoperative, he presented abdominal distension and meningismus. Imaging showed regression of the tumor. The cyst was drained by the shunt. No similar situations were reported in the literature

Intracranial inflammatory pseudotumour related to IgG4: A very rare case

Background: Intracranial inflammatory pseudotumours (IPT) are rare entities that frequently lead to misdiagnosis with malignant lesions. The identification of these lesions is difficult, but important to avoid inadvertent iatrogenicity and to adjust therapeutic protocols. Case Presentation: We report the case of a 30-year-old man who presented a single tonic-clonic seizure. Brain imaging showed a right frontal lesion with intra and extra axial components. Facing the radiologic presentation, a brain tumor was suspected, thus the patient underwent surgery. Pathological exam concluded to a plasma cell granuloma. A whole-body CT-scan showed only a thoracic aortitis. Complete blood work studies came back negative. The patient was also tested for an array of antibodies among which antinuclear antibodies were positive (blood level superior to 1/100). CSF evaluation revealed clear fluid with normal glucose concentration, normal protein levels and lymphocytic pleocytosis. Finally, IgG-4 plasma levels were elevated which led to the diagnosis of an IgG4-RD. The patient was put under prednisolone with a favorable outcome. Conclusion: IPT have several etiologies, among which IgG4 related disease may be one of the less known as only 2 cases have previously been reported. Herein, we report a new case of a young man who presented for seizures related to an intracranial lesion of an IgG4 related disease. The challenge is to suspect such conditions to avoid unnecessary surgeries

Polyuria and polydipsia revealing a pituitary metastasis: Report of a rare case

Abstract Sellar region is a rare localization for intracranial metastases. The diagnosis is frequently delayed as symptoms are generally non specific. Radiologic diagnosis may be difficult as these tumours present similiraities to other more frequent sellar tumours. There is still no consensus regarding therapeutic approach. Prognosis is related to several features
