Cerebral Salt Wasting Syndrome Associated with Pseudomonas Meningitis ccurred after Removal of Pituitary Adenoma: A Case Report

ABSTRACT

The authors report a case of cerebral salt wasting(CSW) syndrome followed by diabetes insipidus and meningitis after transsphenoidal approach for pituitary adenoma. Fluid and electrolyte imbalance occurs occasionally in neurosurgical patients due to DI or SIADH, however, CSW is different disease entity and the methods of treatment are different from those of DI or SIADH. A number of studies in recent years have shown that hyponatremia in many patients with intracranial disease might actually be caused by CSW in which a renal loss of sodium leads to hyponatremia and massive urinary water loss. CSW of this patient was resolved by fluid and salt replacement after 6 months.
