Endoscopic Treatment of Temporal Arachnoid Cysts in 34 Patients.

Cystoperitoneal shunt as alternative treatment for a giant thoracic meningocele in a patient with neurofibromatosis.

Background: Thoracic meningoceles are associated with neurofibromatosis 1 in 60% to 85% of all cases. Usually, these meningoceles remain asymptomatic, but back pain, headache, cough, and dyspnea are possible manifestations. Often, there is an associated kyphoscoliotic deformity of the thoracic spine.

Dual occurrence of pineal germinoma and testicular seminoma. Case report and review of the literature.

A 16-year-old male presented with obstructive hydrocephalus secondary to pineal germinoma. There have been many reported cases of abdominal metastasis of pineal germinoma after ventriculoperitoneal shunting. Endoscopic ventriculostomy was preferred in our case, thus avoiding iatrogenic peritoneal seeding, but spinal metastasis was unavoidable.

Navigated dorsolateral suboccipital transcondylar (NADOSTA) approach for treatment of hypoglossal schwannoma. Case report and review of the literature.

Hypoglossal schwannoma is a rare skull base neoplasm, which lies in the midst of extremely complex anatomical structures. We report a 39-year-old man who presented with a history of right glossal hemiatrophy, dysesthesia and weakness of the left extremities. These symptoms were caused by a unilateral hypoglossal schwannoma located at the cranial base.
