摘要:

&NA;A case of presumed embolic transient ischemic episodes and multifocal infarcts to the occipital and parietal cortices and the cerebellum of a young woman with ulcerative colitis is reported. These episodes were manifested by multifocal neurologic deficits including cortical blindness, visual hallucinations, and homonymous hemianopsia. They correlated with parenteral nutrition via a central line, presumed venous, but found to be in the subclavian artery. The complications of central venous lines are reviewed. The need for attention to neighborhood structures and unexpected symptoms, in view of the less well‐recognized arterial embolic complications is emphasized.

摘要:

&NA;A 9‐year‐old girl presented with profoundly decreased vision in both eyes and bilateral optic disc swelling. Magnetic resonance imaging showed a large intraventricular mass. Excisional biopsy diagnosed metastatic adrenal cortical carcinoma (ACC). This is, to the best of our knowledge, the first reported case of ACC metastatic to the brain in a child. It also illustrates the importance of differentiating optic neuritis from papilledema in children.

摘要:

&NA;The authors present a spectrum of clinical presentations of transient visual loss/aberrations and show that these occurrences were attributable to ingestion of significant amounts of licorice. A case series of five patients was seen at Geisinger Medical Center between October 1986 and May 1996. Details of patient presentation, treatment, and outcome are discussed. The literature on the effects of licorice derivatives on vascular smooth muscle function is reviewed. Of the five patients, two had documented visual loss by visual acuity testing and visual fields. All patients reported a recent ingestion of significant amounts of licorice (¼‐2 lbs.). All patients had resolution of their visual symptoms; the aid of hyperbaric oxygen was required for one patient. Thorough review of the literature shows recent in vitro and in vivo evidence of glycyrrhetinic acid (the active component of licorice) and carbenoxolone (the hemisuccinate derivative of glycyrrhetinic acid) directly and indirectly enhancing vasoconstrictor action in vascular smooth muscle. It is believed that licorice derivatives can cause retinal or occipital vasospasm, giving rise to transient monocular or binocular visual loss/aberrations. This has not been described before in the literature. It is important to ask about licorice ingestion with patients who present with these visual symptoms.

摘要:

&NA;A patient with generalized inflammatory polyneuropathy and facial diplegia was studied with magnetic resonance imaging. Multiple cranial nerves showed signal enhancement without sensory or motor dysfunction.

摘要:

&NA;Cysticercosis of the optic nerve has been reported only twice in the literature. A case of optic nerve cysticercosis in a 50‐year‐old woman with atypical optic neuritis is reported. Computerized tomography showed a thickened left optic nerve with a ring‐enhancing lesion containing an eccentric nodule. An enzyme‐linked immunosorbent assay test for cysticercosis further established the diagnosis. The patient was treated with oral prednisolone and albendazole, with no improvement in vision.

摘要:

&NA;Miller‐Fisher syndrome (MFS) is characterized by variable ophthalmoplegia, ataxia, and tendon areflexia. It seems to be a variant of Guillain‐Barré syndrome (GBS), but unlike in GBS, there is a primitive involvement of the ocular motor nerves, and in some cases there is brainstem or cerebellum direct damage. The unusual case of MFS in the current study started with a bilateral areflexical mydriasis and a slight failure of accommodative‐convergence. Ocular‐movement abnormalities developed progressively with a palsy of the upward gaze and a bilateral internuclear ophthalmoplegia to a complete ophthalmoplegia. In the serum of this patient, high titers of an IgG anti‐GQ1b ganglioside and IgG anti‐cerebellum, anti‐Purkinje cells in particular, were found. The former autoantibody has been connected to cases of MFS, of GBS with associated ophthalmoplegia, and with other acute ocular nerve palsies. The anti‐cerebellum autoantibody could explain central nervous system involvement in MFS. The role of these findings and clinical implications in MFS and in other neuroophthalmologic diseases are discussed.
