Retroperitoneal hemorrhage from renal angiomyolipoma

Case contributed by Behrang Amini
Diagnosis almost certain

Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.

Axial CT through the kidneys shows a fat-attenuation lesion in the left kidney with a perirenal collection, most likely blood. This is consistent with a bleeding angiomyolipoma.
