Routine thin-section CT after contrast enhancement may fail to demonstrate smal l acoustic neuromas, usually those small er than 10 mm [1, 2]. Metrizamide CT cisternography has demonstrated such small acoustic neuromas, but cannot demonstrate an intracanalicul ar tumor accurately [3]. Pantopaque c isternography can demonstrate an intracana-li c ul ar mass,(More)
We studied a case of cavernous hemangioma of the middle cranial fossa. This rare tumor, of which only nine prior cases have been recorded, is characterized by insidious visual loss, multiple cranial nerve pareses, proptosis, papilledema, and bitemporal hemianopsia. Pituitary dysfunction has been noted in the more advanced cases. The female-male ratio has(More)
Magnesium deficiency in weanling rats caused an increase in NEL and in audiogenic seizure susceptibility. These behavioral effects were apparent after eight days of magnesium restriction and could be reversed by dietary rehabilitation. Serum magnesium declined rapidly from 1.87 +/- 0.10 mEq/L to 0.91 +/- 0.24 mEq/L in two days. Cerebrospinal fluid (CSF)(More)
Weanling male rats fed a low magnesium diet for 14 days were protected from audiogenic seizures by administration of phenobarbital and diphenylhydantoin. Amphetamine, levo-dopa, and magnesium chloride injected 45 minutes prior to testing did not prevent the seizures. In contrast to weanling male rats which became mortally seizure prone, 3--5 week-old female(More)
Cerebral intraventricular injections of 17 and 50 microgram magnesium in artificial cerebrospinal fluid progressively depressed the Non-specific Excitability Level of permanently cannulated 150--200 g rats fed a low magnesium diet for 21 days. Compared with control diet, a low Mg diet caused an increase in brain serotonin. Weanling rats fed a low Mg diet(More)
