The afferent projections to the inferior colliculus of the rat were studied using the method of retrograde transport of horseradish peroxidase (HRP). Following large injections of HRP into the central nucleus, cells within the cochlear nuclei, superior olivary complex and auditory cortex were stained. Within the contralateral dorsal cochlear nucleus,(More)
Peripheral aneurysms of the posterior inferior cerebellar artery (PICA) are rare. The authors describe a case in which five distinct peripheral aneurysms of the PICA were diagnosed and microsurgically clipped while preserving the parent vessel. One of the aneurysmal sacs was excised and examined pathologically, and no evidence of an infectious etiology was(More)
A 44-year-old man experienced the sudden onset of horizontal diplopia and hemifacial numbness. Arteriography demonstrated a left intrapetrous carotid artery aneurysm. The patient was successfully treated with a left superficial temporal artery to middle cerebral artery bypass followed by balloon entrapment of the aneurysm. There have been at least 40(More)
A case of lymphocytic adenohypophysitis in a postpartum woman who became symptomatic during her 8th month of pregnancy is presented. The clinical presentation, endocrine findings, pathological findings, and operative management are discussed. Transient hypopituitarism is documented. Unlike most previously published cases, this woman had complete recovery of(More)
Horseradish peroxidase conjugated to wheat germ agglutinin (HRP-WGA), and bisbenzimide (a fluorescent dye) were used as retrograde axonal tracers to examine whether or not intracranial and extracranial trigeminal afferents represent divergent axon collaterals. HRP-WGA was applied to the proximal segment of the middle cerebral artery and bisbenzimide was(More)
A case of cervical diastematomyelia in an adult is reported. The patient first noted sensory and motor symptoms at 34 years of age after two episodes of cervical trauma. Metrizamide computerized tomography myelography of the cervical spine and cord showed the region of diastematomyelia and revealed a spur containing both bone and fat tissue projecting into(More)
Neurogenic pulmonary edema (NPE) occurs in association with central nervous system disease without underlying cardiopulmonary problems. It is characterized by profound pulmonary vascular congestion and a fulminant clinical course. Although several reports document a role for experimental brain-stem lesions in the production of NPE, there have been only two(More)
The inferior olivocerebellar projection of the normal inbred C57BL/6J mouse was visualized after anterograde transport of horseradish peroxidase conjugated to the lectin wheat germ agglutinin (HRP-WGA conjugate). Following injections of HRP-WGA conjugate which filled the entire inferior olivary nucleus on one side, olivocerebellar fibers were followed(More)
