THE SYNDROME of inappropriate antidiuretic hormone (SIADH) secretion is characterized by serum hyponatremia and hyposmolality associated with relative urinary hyperosmolality and excessive renal salt loss; there is an absence of clinical evidence of fluid volume depletion, and renal and adrenal function are normal.1 The subject of this report, a child with a hypothalamic glioma, fulfilled all of these criteria and, in addition, showed several atypical features of the SIADH. These included a normal response to an acute water load, the occasional failure to respond to severe water restriction, and the discontinuous secretion of a measurably elevated ADH co-existing with persistent hyponatremia. These features are not inconsistent with the inappropriate secretion of ADH. A possible alternative explanation is that a malfunctioning hypothalamic "osmostat" may be an associated defect.
