title: [A case of huge renal angiomyolipoma calculated doubling time].
abstract: A 32-year-old man was admitted with a sudden onset of severe left flank pain. The abdominal and MRI showed bilateral renal tumors with left perirenal hematoma. Selective right renal biopsy under the guidance of ultrasonography revealed that right renal tumor was angiomyolipoma (AML). After performing left renal embolization of the left renal artery, left was performed. The histology of the excised specimen was also AML. This patient had visited to the other clinics in 1985 and in 1988, and was examined by CT. Accordingly, doubling time of this tumor was calculated by ellipsoid method. Doubling time in 1985-1988 was days, and that in 1988-1995 was 675 days. Growth change of left renal AML did not show curve.
