Leukemic infiltration of the Meninges and brain is frequent in childhood leukemia.1 Laakso2 found 13 reports of diabetes insipidus in patients with leukemia, and only one of these was a child.3 Rosenzweig and Kendall4 have reported another patient with diabetes insipidus complicating acute leukemia. Malter et al5 described a 10-year-old child with diabetes insipidus complicating acute lymphocytic leukemia. Physiologic studies suggested local invasion of the posterior pituitary, but histologic confirmation of this was not available. We have studied and treated a child with erythromyelocytic leukemia who developed diabetes insipidus during the course of his disease. Localization of the leukemic infiltrate in the pituitary stalk was demonstrated.
