Meningococcal meningitis and diabetes insipidus.

A 20-year-old woman with a transient diabetes insipidus as a complication to meningococcal meningitis is presented. This condition has only been described once before. Culture of blood and spinal fluid yielded Neisseria meningitidis group B, sensitive to penicillin. The diabetes insipidus arose on day 4 after admission and continued to day 15. Treatment comprised benzylpenicillin, DIC therapy, assisted ventilation, and vasopressin.
