摘要:

We report a 56-year-old female with a 50-year history of a progressive chiasmal syndrome who was found to have a suprasellar arteriovenous malformation involving the chiasm and both optic nerves associated with an unusual fundus picture consistent with the Wyburn-Mason syndrome. A review of the literature of this rare syndrome is also presented.

摘要:

Partial or complete occlusion of the internal carotid artery is a familiar consequence of severe atherosclerosis seen in the elderly. Complete obstruction of both internal carotids is rare, particularly in the young or middle-aged. The rapid onset of bilateral internal carotid occlusion would be expected to produce devastating neurological sequelae and probably not be compatible with survival. We present a case of a young man with complete obstruction of both internal carotid arteries whose presenting symptoms were those of a visual field cut. The history suggests that the carotid occlusion occurred as a result of blunt trauma. The patient had no known predisposition to vascular abnormalities (no history of hypertension, hyperlipidemia, signs of systematic arteriosclerosis or vasculitis, and an unremarkable family history for vascular abnormalities). Computerized tomography revealed an infarct in his right parietal lobe. Angiography demonstrated complete occlusion of both internal carotid arteries and the right posterior communicating artery and failed to disclose the development of extensive collatorals, adding further evidence to the acuteness of the occlusion. The patient was followed by noninvasive studies and in the subsequent year showed marked neurological and ophthalmological improvement.

摘要:

We report five cases of presumed orbital myositis mimicking extraocular muscle motility disturbances and manifesting clinical signs of active inflammation over the involved muscles. Computed tomographic evidence for exraocular muscle enlargement is helpful in confirming the diagnosis. If not present or atypical, another etiology should be sought. All patients responded rapidly and dramatically to systemic corticosteroids. Anterior inflammation may be accompanied by iritis and respond to topical corticosteroids. We believe the diagnosis of orbital myositis may be made on clinical grounds with confirmation by computed tomographic evidence for extraocular muscle enlargement and clinical response to corticosteroids. Biopsy is unnecessary except in atypical cases.
