A case of a meningeal B-cell lymphoma is described. A 48-year-old man presented with an episode of grand mal seizure following a brain injury. An initial diagnosis of extradural hematoma was made based on the results of the cerebral computerized tomography scan. Magnetic resonance images demonstrated an enhanced mass with a dural tail attached to the meningeal layer of the temporal bone, suggesting a meningioma "en plaque". The mass was surgically excised. Tumoral removal was subcomplete (Simpson 2). Operative inspection also suggested a meningioma, but histological analysis and electron microscopy revealed a grade IV follicular B-cell lymphoma. Biological studies were normal. An extensive workup found an external iliac adenopathy with several osseous locations on PET. The patient underwent chemotherapy and radiotherapy. Three years after the first symptoms appeared, the patient is alive and free of symptoms. The clinicopathological features and treatments were discussed.

Giant intracranial aneurysms in the paediatric population: Suggested management and a review of the literature.

OBJECTIVES: Intracranial aneurysms are rare in children although giant aneurysms more commonly occur in adolescence. The aims of our study were to perform an extensive review of the literature over the past two decades and assess intracranial aneurysm management. METHODS: Based on a Pubmed search, we carried out a review of the literature from 1990 to 2012 regarding giant intracranial aneurysms diagnosed in the paediatric population. This descriptive study concerned clinical presentation, cerebral aneurysm characteristics, therapeutic management procedures and outcome. RESULTS: Forty-six cases were reported in 31 papers. The male/female sex ratio was 1.15, the clinical presentation was a tumour mass syndrome in 56.6%, followed by rupture in 30.4%. The aneurysm location was the posterior circulation in 41.3%, and microsurgical treatment (52.2%) predominated over endovascular coiling (28.3%). CONCLUSION: To date, no evidence-based medicine recommendation has been accepted for the management of rare intracranial aneurysms. Each reported patient was the object of a multidisciplinary clinical decision. Management of this challenging pathology should be performed on a case-to-case basis.

Non-traumatic pseudocyst of Glisson capsule complicating a ventriculoperitoneal shunt.

BACKGROUND: Cerebrospinal fluid pseudocysts in the peritoneal cavity following ventriculoperitoneal shunt are relatively uncommon. In these complications, perforation of solid organs is unusual. CASE DESCRIPTION: A case of subcapsular hepatic pseudocyst is described. A 48-year-old man treated by ventriculoperitoneal shunt presented with abdominal pain. Laboratory examinations revealed hepatic cytolysis. The CT-scan of the abdomen demonstrated a small ovoid non-enhanced cystic collection in the subcapsular area of hepatic segment V. Percutaneous hepatic fine-needle aspiration of the cyst guided by abdominal ultrasonography showed no abnormal findings. Peritoneal reimplantation at a different site was performed. The clinicopathological features of this entity are described and treatments are discussed. CONCLUSION: Reinsertion of the catheter at a different abdominal site is effective in non-infections cases. In contrast, a temporary external drainage with adequate antibiotic treatment followed by shunt reinsertion is necessary to treat a documented infection of CSF collections.
