Syndrome of inappropriate secretion of antidiuretic hormone in enteroviral meningitis

S. Chemtob, E. R. Reece and E. L. Mills

In nine of 102 children admitted to the Montreal Children's Hospital with a diagnosis of aseptic meningitis, the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) developed. Patients with and without SIADH were similar with respect to clinical symptoms, duration of illness, and CSF inflammatory response. The SIADH group differed in that the largest age group was 1 to 5 years.
