Renal angiomyolipoma

Case contributed by Dr Roberto Schubert

Presentation

Left flank pain and haematuria. Ultrasound showed a heterogeneous, predominantly hyperechoic mass of the left kidney.

Patient Data

Age: 40 years
Gender: Female
MRI

MRI showed a T1 hyperintense fatty lesion with abundant Indian ink artifacts on opposed phase gradient-echo images and moderate reticular enhancement of the non-fatty components. 

3D LAVA showing signal loss of the lesion due to fat saturation and contrast enhancement of the myovascular components.

Case Discussion

MRI features are suggestive of renal angiomyolipoma. MRI is of value in assessment of fat-containing lesion, showing signal loss on fat-saturated sequences and loss of signal on T1 out of phase sequence.
