A 72-year-old male was admitted to our hospital with a 2-year history of polyuria, prosopagnosia and aphasia. He showed characteristric clinical features of Pick's disease such as stereotyped verbal output and behavior and personality changes. CT and MRI scans showed marked atrophy in the bilateral anterior temporal lobes mild atrophy of the bilateral frontal lobes. SPECT scans revealed perfusion abnormalities in corresponding areas. A 6-hour-water deprivation test resulted in decrease in the urine volume and in concentration of the urine, suggesting abnormality of his secondary drinking behavior. Polyposia resulting in polyuria as a clinical manifestation may be due to stereotypic behavior which is often seen in Pick's disease.
