title: Diabetes insipidus associated with dysplastic pancytopenia.
abstract: This case report describes a 60-year-old man who presented with a three-year history of generalized malaise, decreased libido, polyuria, and polydipsia. He had been previously investigated for pancytopenia, and found to have a hypoplastic bone marrow. A diagnosis of central diabetes insipidus was established; the patient was also found to have a number of other defects in his hypothalamic-pituitary function. Hematologic studies again revealed peripheral pancytopenia associated with a hypoplastic megaloblastic bone marrow. Computed axial and nuclear magnetic resonance tomography failed to establish the nature of the morphologic lesion in the hypothalamus. A possible relationship between the hematologic and endocrine disturbance is discussed.
