BACKGROUND Trigeminal neuralgia may be idiopathic or secondary to a number of cranial pathologies. We report a novel case of trigeminal neuralgia associated with Dandy-Walker malformation, which may be an etiologic factor. CASE DESCRIPTION A 32-year-old male presented with shock-like pain in the somatosensory distribution of the right trigeminal nerve, which was refractory to all medication. ...

OBJECTIVE The aim of this study is to describe the results of 16 patients with posterior fossa hemangioblastoma, treated with microsurgical techniques. METHOD Between June 2005 and December 2015, 16 patients with posterior fossa hemangioblastoma were operated on, underwent microsurgical resection. The sex, age, imaging findings, symptoms, and postoperative results were analyzed. RESULTS Ele...

BACKGROUND AND PURPOSE Injury to the dentatothalamic pathway that originates in the cerebellum has been suggested as a mechanism for neurologic complications in children treated for posterior fossa tumors. We hypothesized that time-dependent changes occur in the dentatothalamic pathway. MATERIALS AND METHODS Diffusion tensor evaluation was performed in 14 children (median age, 4.1 years; age ...

Up to 25% of children who undergo brain tumor resection surgery in the posterior fossa develop posterior fossa syndrome (PFS). This syndrome is characterized by mutism and disturbance in speech. Our hypothesis is that there is a correlation between PFS and the occurrence of hypertrophic olivary degeneration (HOD) in structures within the posterior fossa, known as the inferior olivary nuclei (IO...

Intracranial hemangiopericytoma is unusual, and those occurring in the posterior fossa is extremely rare; we report such a rare case of hemangiopericytoma of the posterior fossa. The radiologic findings and gross characteristics of hemangiopericytomas are sometimes quite similar to those of meningiomas. Although extremely rare, the operator should be aware of the existence of this disorder to d...

All rights reserved Background: Posterior fossa arachnoid cysts cons tute 10-11% of all intracranial arachnoid cysts and are considered to be the second most common after middle fossa arachnoid cysts. Their diagnosis, indications of surgical intervention and mode of surgical management are still points of debate. Objective: We report our experience in the...
