Neurenteric cyst of the lower clivus.

Objective: Neurenteric cysts (NCs) typically arise as benign ventral intradural extramedullary developmental malformations of the spine which contain heterotopic epithelium resembling the intestinal or respiratory tracts. Intracerebral NCs are extremely rare, though the frequency of symptomatic reports and incidental findings is increasing, perhaps because of advances in neuroimaging. Recognition of the unique radiographic and histopathologic features of this entity is of growing importance in the treatment of cysts of the neural axis.

Spontaneous epidural pneumocephalus.

A 20-year-old male presented with an extremely rare spontaneous epidural pneumocephalus which was successfully treated by a single neurosurgical intervention. The patient had a habit of nose blowing and a 1-year history of progressive headache and nausea. Cranial computed tomography (CT) revealed a 2 x 7 cm right temporo-occipital epidural pneumocephalus with extensive hyperpneumatization of the mastoid cells.

Intradural microsurgery and extradural gamma knife surgery for hypoglossal schwannoma: case report and review of the literature.

There have been only 26 cases of hypoglossal schwannomas reported to originate intradurally and extend extradurally into the hypoglossal canal. This 31-year-old mother of two children presented with a 5-day history of progressive headache, nausea, vomiting and vertigo. Her neurological exam was significant for nystagmus and left tongue deviation with marked atrophy.

Remote cerebellar hemorrhage after supratentorial unruptured aneurysmal surgery: report of three cases.

We report three cases of remote cerebellar hemorrhage that developed after supratentorial unruptured aneurysmal surgery. In all cases, digital subtraction angiography was performed before each operation in order to rule out other vascular abnormalities, especially around the operative field or the posterior circulation. In addition, all patients were screened for any previous history of bleeding tendencies or other related medical disorders.

Huge arachnoid cyst of the occipital cerebral convexity.

A 68-year-old woman presented with a rare huge right occipital cystic lesion manifesting as progressive left hemiplegia. Cranial computed tomography revealed a 4 x 7 cm right occipital lobe thin-walled cyst with midline shift and compression of the ipsilateral ventricle. The patient underwent a single burr hole operation for cystography and delineation of the cyst anatomy, then a separate right parieto-occipital craniotomy with complete cyst evacuation, corticotomy, and ventriculostomy.

Transient occipitotemporal subcortical diffusion-weighted magnetic resonance imaging abnormalities associated with status epilepticus. Case report.

A 30-year-old man presented with a generalized seizure manifesting as decreased consciousness. Diffusion-weighted magnetic resonance imaging showed transient areas of high intensity in the gray and subcortical white matter of the left occipital and temporal lobes. The lesions did not reflect the vascular territories.
