Describes the CT and MRI imaging characteristics of a rare case of primary renal angiosarcoma presenting with spontaneous rupture and venous thrombosis.
May prompt inclusion of angiosarcoma in differentials for ruptured renal masses; extends sparse case literature without establishing diagnostic criteria.
Primary renal angiosarcoma is a very rare malignant mesenchymal tumor. CT shows a well-margined enhancing mass with hemorrhage, perirenal hematoma and renal vein thrombosis in the lower pole of the right kidney. MRI shows heterogeneous low- and high-signal intensities of the mass on T1- and T2-weighted images, as well as a relatively homogeneous enhancement on contrast enhanced T1-weighted images. We report here on a rare case of primary renal angiosarcoma with spontaneous rupture and venous thrombosis.
