Inappropriate antidiuretic syndrome hypersecretion after a single dose of cisplatin.

ABSTRACT

Severe hyponatremia with seizure owing to the syndrome of inappropriate antidiuretic hormone secretion (SIADH) or cerebral/renal salt wasting syndrome related with high mortality. The correct diagnosis of the hyponatremia for each case is important because of the alteration of the treatment approach. SIADH is an important clinical manifestation that does not occur after all chemotherapy courses. We cannot estimate whether the disease will occur on, which course of the chemotherapy in this case.
