Glioblastoma Following Treated Medulloblastoma After 29 Years in the Posterior Fossa: Case Report and Review of Literature.

Glioblastoma multiforme (GBM) is a high-grade glioma that may be a rare complication of radiotherapy. We report a case of a patient who was treated for medulloblastoma (MB) of the posterior fossa at the age of 27 years. Twenty-nine years later, at the age of 56 years, he presented with a double-location tumor: supratentorial and in the posterior fossa. Imaging features of the supratentorial location were very suggestive of a meningioma. We operated on the posterior fossa location, which revealed a glioblastoma. Histologically, the tumor cells exhibited characteristics of both GBM and rhabdoid tumor cells. Literature reports of cases of GBM following MB at the same place are very rare, and presenting rhabdoid characteristics is even rarer. This is the first case of MB and GBM at ages 27 and 56 years, respectively. The double-location supratentorial probable meningioma and GBM of the posterior fossa 32 years after MB is the only case reported in the literature. What to do in this case remains a topic of debate, and there are no clear recommendations in the literature.

Pediatric brain hydatid cyst about two cases: Case report.

Cerebral hydatid cyst is rare (2%), and mainly affects children. We report 2 cases aged 5 years. The clinical symptomatology was dominated by intracranial hypertension syndrome and motor deficit in both cases. One patient presented a generalized tonic-clonic seizure, the second one presented a left central facial palsy. The diagnosis was made in both cases by brain CT scan and one patient underwent brain MRI. A radiological workup to look for extra-cerebral localization was performed for all patients, which was normal. The treatment was surgical for both patients (D'ARANA-INIGUEZ hydro pulsion technique) with simple after-effects. The postoperative CT scan showed a residual cavity. All our patients were put under antiparasitic treatment with Albendazole.

A rare complication of ventriculoperitoneal shunt: Pleural effusion without intrathoracic ventriculoperitoneal shunt catheter.

BACKGROUND: Symptomatic pleural effusion following ventriculoperitoneal shunt (VPS) insertion is very rare and poorly understood in the literature in contrary to other mechanical complications. CASE DESCRIPTION: We report a case of 15 month-year-old girl who had VP shunt for congenital hydrocephalus. Twelve months after surgery, she was diagnosed with massive hydrothorax. Chest X-ray and thoracoabdominal CT scan confirmed the right pleurisy and showed the tip of the peritoneal catheter in the general peritoneal cavity. We made thoracic drainage of the transudative pleural effusion. When we released the chest tube, 24 h after, the girl showed a respiratory distress again and the effusion resumed at the X-ray control. Her symptoms abated after the realization of a ventriculoatrial shunt "VAS." Repeat chest X-ray confirmed the resolution of the hydrothorax. CONCLUSION: Despite the not yet well-understood mechanism of this rare and important VPS complication, management is simple based on X-ray confirmation, thoracentesis with biological analysis, and catheter replacement, especially in atrium "VAS."
