Intraspinal lipomas are rare, benign neoplasms, comprising less than 1% of all intradural spinal tumors. Such tumors occur in the thoracic and cervical region, however, extension into the posterior fossa is most unusual. A case of large cervical intradural spinal liplma with extension into the posterior fossa in adult female is presented. Clinical feature was slowly progressing quadriparesis. Brain and cervical spine computed tomography confirmed the diagnosis and Magnetic resonance imaging was very useful for delineation of the anatomy of the lipoma as an aid in planning the operation. Operative therapy consisted of combined suboccipital craniectomy, spinal laminotomy and laminoplasty, subtotal tumor decompression.

Interference with visual pathways is usually not caused by intracranial aneurysms. Aneurysms of the anterior communicating artery rarely produce visual symptoms and signs in spite of their proximity to the visual pathways. The reason may be that these aneurysms rupture and present with subarachnoid hemorrhage before becoming large enough to exert significant pressure on the chiasm or optic nerves. The visual symptoms would be presented as visual field defect or impaired vision. These can be explained as the result of direct compression of the optic pathways, ischemic changes in the visual pathways caused by severe vasospasm after subarachnoid hemorrhage, or intraocular pathology such as retinal hemorrhage. 2 cases of anterior communicating artery aneurysms associated with visual symptoms are presented with a brief review of literatures.

Ectopia Cordis*

The application of stereotactic techniques and endoscopy dates back to the beginning of this century and is almost as old as neurosurgery itself. However, endoscopic techniques progressed slowly for several reasons. A reappraisal of endoscopic techniques become popular about 1985. The major indication of endoscope in neurosurgical field is intraventricular procedures. Recently it can be used selectively in the intraaxial mass lesion associated cavity. For example, cystic mass, with liquefied necrosis, blood clot can be approached with endoscope. Authors present its intraaxial application in basal ganglionic hematoma in three patients. Conventional stereotactic guidance of neuroendoscope was done and the hematoma was gently removed through continuous irrigation and suction under video-guidance. The clinical course was uneventful. Brief overview is given of this intraaxial neuroendoscopic procedure.
