title: [Renal hemangiopericytoma discovered at a health screening: a case report].
abstract: We report a case of renal hemangiopericytoma which was incidentally discovered by ultrasonography at a health screening. A 58-year-old man was admitted to our hospital for close examination of the renal tumor. Computed tomography revealed the left renal tumor, 60 x 50 mm in size, which was well enhanced with contrast medium. Magnetic resonance imaging revealed an isointensity mass (T1-weighted) and high-intensity mass (T2-weighted) at the left kidney. Radical nephrectomy was performed on suspicion of left renal cell carcinoma. Histopathological examination revealed renal hemangiopericytoma. The present case is the 7th in the Japanese literature.
