摘要:

This article reviews the advances in neurosurgery, neuroradiology, and neuroendocrinology that have altered the management of patients with pituitary adenomas. These benign tumors can produce significant morbidity including loss of vision. Morbidity may be avoided or corrected if available diagnostic and therapeutic options are instituted appropriately.

摘要:

We report three patients who developed symptomatic visual loss following uncomplicated general surgical procedures. All three patients had ocular examinations and visual field deficits consistent with acute ischemic optic neuropathy. All three had hemoglobin levels be-low normal limits at the onset of visual symptoms. However, none of the patients suffered intraoperative or postoperative hemorrhaging. Ischemic optic neuropathy may occur following general surgical procedures, not complicated by significant hemorrhaging.

摘要:

A 35-year-old man with aplastic anemia developed prominent downbeat nystagmus 80 days after receiving an allogeneic bone marrow transplant. A diagnosis of herpes simplex encephalitis was made which was confirmed by positive virus cultures at autopsy 1 week later. Routine pathologic examination of the brain stem revealed no lesions which would explain the downbeat nystagmus. Immunoperoxidase studies, however, revealed virus-infected neurones throughout the brain stem including the nuclei of the basis pontis, the superior olive, and nuclei of the spinal tracts of 5 and 10. The significance of “negative” pathologic brain stem findings in cases of downbeat nystagmus is discussed.

摘要:

Four cases of intracranial chordomas are reported. Intracranial chordomas initially tend to occur with sixth nerve paresis and subsequently with visual disturbance and optic disc changes. Computed tomography demonstrated an isodense mass in one case, a low-density mass in another case, and both an isodense and a partial high-density in two cases. Histopathologically, isodense areas were coincident with regions of compact tumor cells, low-density areas coincided with abundant mucinous intercellular matrices, and high-density areas were coincident with cartilaginous matrices or calcifications.

摘要:

An intracranial mass lesion is a rare, but reported presenting sign in sarcoidosis. A 39-year-old woman presented with a frontal lobe lesion (pathologically a noncaseating granuloma) associated with chronic progressive visual loss and optic atrophy on the right side. High-resolution axial and coronal computerized tomography revealed a parachiasmal density compatible with the clinical course. Clinical suspicion of granulomatous processes and appropriate workup in all cases of optic neuropathy may allow for early medical therapy in such cases.

摘要:

Twelve patients with recurrent cranial nerve palsies in whom no focal cause was found were seen during a period of 4 years. The literature is reviewed, and the relationship and similarity to Tolosa-Hunt syndrome is discussed. Early recognition is important since the response to steroids, although not specific, is rapid in most patients, and the prognosis for complete recovery is relatively good.

摘要:

A 14-year-old girl had loss of vision in the right eye and bilateral optic disc swelling. After treatment with oral prednisone, the neuropathy resolved. An extensive evaluation led to a probable diagnosis of Toxocara optic neuropathy.
