Case contributed by Dr Heba Abdelmonem


A pregnant female referred for a prenatal ultrasound, abnormal appearance of the bilateral kidneys was observed by the sonographer. CT was requested after delivery.

Patient Data

Age: 32 years
Gender: Female

-Bilateral diffuse involvement of the kidneys with multiple differential densities. The Right-sided mass measured 125x163mm and Left-sided mass measured 130x145 mm.  Both masses have fatty components with CT density -33 HU, contrast enhanced scans showed patchy & heterogeneous enhancement in the soft tissue & vascular component of the mass lesion. Normal excretion of contrast media was seen on both sides.  Multiple areas of blood densities are noted on the right side suggests possible hemorrhage.The uterus is still sub involuted.

Case Discussion

Young female with long history of chronic anemia, abnormal appearance of both kidneys was discovered accidentally. CT images demonstrate bilateral giant Renal angiomyolipomas. Being a common complication with giant angiomyolipomas more than 5 cm, hemorrhage may be the direct cause of the patient long-lasting anemia. The patient's renal function was within normal. 

The patient had multiple facial angiofibroma by inspection which raises the odds of tuberous sclerosis, a CT brain was requested.
