A case of non-neoplastic pineal cyst with Parinaud's syndrome is presented. A 54-year-old woman was admitted to the department of neurosurgery. Fukui Medical School on October, 1985, complaining of the paralysis of upward gaze. A computed tomography (CT) demonstrated a low density mass in the pineal region and the mass was not enhanced after the injection(More)
A 29-year-old man with Cockayne's syndrome (CS), presenting reversible ischemic neurological deficit is reported. In his past history, hearing disturbance developed at 6 years old and visual disturbance at 12 years old. His parents have consanguinious marriage. He came to our hospital complaining of right-sided hemiparesis and speech disturbance. He was(More)
Eighteen patients were studied for cerebral blood perfusion abnormalities using N-isopropyl I-123 p-iodoamphetamine (IMP) and rotating dual gamma camera emission computed tomography (ECT). All were stroke patients, 10 with cerebral vasospasm after an aneurysmal rupture, 3 with an occlusion of the middle cerebral artery, 2 with an occlusion of the internal(More)
SUMMARY We report a case of dural arteriovenous fistula (DAVF) within the left hypoglossal canal in a 64-year-old man who presented with tinnitus and ocular symptoms. Angiography revealed DAVF with the fistulous pouch medial to the left jugular bulb. The fistula was feeded by meningeal branches of the bilateral ascending pharyngeal arteries and the branches(More)
Structurally normal myelin sheaths develop in the spinal cord of juvenile myelin-deficient rats (mdr) 11 days after transplantation of normal fetal spinal cord fragments or cultured cells that do not yet express galactocerebroside. Cultures result in more extensive myelin formation, and in both cases the myelin that forms is located primarily at or near the(More)
We have identified three examples of female Wistar rats exhibiting the tremor and seizures characteristic of the X-linked myelin deficiency (md) mutation, which is ordinarily seen only in males. Cytogenetic study of two of these animals has shown them to have 41 chromosomes instead of the normal 42. The missing chromosome was identified as an X chromosome(More)
A woman with Addison disease developed hyperpigmentation, headache, and nausea despite conventional replacement therapy with cortisone. Excessively elevated plasma adrenocorticotropic hormone (ACTH) with absence of response to administration of corticotropin-releasing factor (CRF), and roentgenological evidence of enlargement of the sella turcica, as well(More)
Nodal and paranodal regions of myelinated sciatic nerve fibres from diabetic (db/db) mice were examined in freeze fracture replicas. In some fibres, the axolemma was found to display abnormalities in the paranodal region. These include shallow, undifferentiated junctional indentations, thinning of the indentations with widening of the non-junctional grooves(More)
A case of intracranial malignant melanoma associated with nevus of Ota is presented. A 77-year-old man was admitted to the department of neurosurgery, Fukui Medical School on June, 1985 because of developing disturbed consciousness. The physical examination on admission revealed pigmented lesion diagnostic of the nevus of Ota, anisocoria (R greater than L)(More)
The intracranial pressure (ICP) irregularities, i.e., pressure waves, were studied in dogs with experimental subarachnoid hemorrhage. Animals were lightly anesthetised, immobilised with panchronium bromide and respirated artificially. Subarachnoid infusion of hemolysed red blood cells was used to induce intracranial hypertension. Recordings of both systemic(More)
