Renal angiomyolipoma

Case contributed by Mohammad Farghali Ali Tosson
Diagnosis almost certain

Presentation

Epigastric pain.

Patient Data

Age: 25 years
Gender: Female
ct

Large, exophytic heterogeneous rounded and well-defined right renal mass, arising from its upper pole, predominantly of fat attenuation. The lesion measures 4.5 x 4.5 x 5 cm, mostly in keeping with a renal angiomyolipoma. 

Another two small lesions of the same appearance are seen adjacent to the large mass.

Case Discussion

Typical renal fat-containing lesion discovered incidentally during an abdominal ultrasound examination. When an AML has typical appearances there is essentially no differential.
