Abstract

Cerebral Salt Wasting Syndrome (CSWS) is defined as the development of extracellular volume depletion due to a dysfunction of the renal sodium transport system. Differentiation of CSWS from the Symdrome of Inappropriate Secretion of Antidiuretic Hormone in patients with intracranial disease is difficult because both syndromes include hyponatremia and concentrated urine with natriuresis. However, distinguishing between these two syndromes is very important because the treatment options differ. We report a 41 year-old Asian woman who presented initially with hyponatremia, and was finally diagnosed with CSWS after an operation for an acoustic neuroma. Based on this case, we discuss a possible mechanism and disclose insights about differential diagnosis thereof.
