The Schwannoma Involving the Orbit

We report the case of a 48-year-old man with schwannoma involving the orbit. Computerized tomography and magnetic resonance imaging revealed a 2X3X2cm-sized well-enhanced round lesion which mildly compressed the optic nerve. The patient underwent fronto-orbitotemporal craniotomy, with successful total removal of the tumor. To our knowledge, this is the first report of schwannoma involving the orbit : a review of the literature is also included.

A Case of Cerebral salt Wasting Syndrome with Pseudomonas Meningitis after Removal of Pituitary Adenoma / 대한내분비학회지

Hyponatremia is frequently seen in intracranial hemorrhagic patients and has been often attributed to inappropriate secretion of antidiuretic hormone. But in recent years, a number of studies have shown that hyponatremia in many patients with intracranial disease may actually be caused by cerebral salt wasting (CSW) syndrome and circulating Atrial natriuretic peptide (ANP) and Brain natriuretic peptide (BNP) are probably involved. This report describes a patient who developed bacterial meningites caused by pseudomonas aeruginosa and CSW syndrome after removal of pituitary adenoma. CSW syndrome resolved by fluid and salt replacement after 4 months.
