ABSTRACT

Diagnosis: Angiomyolipoma

History: 68-year-old female with a 30-pack-year smoking history, presents with cough and nose bleed. CXR reveals a nodular density, which further evaluated with chest CT. Chest CT has incidental finding of possible hepatic vascular malformation. Abdominal ultrasound is recommended to evaluate liver findings. During abdominal ultrasound, four echogenic masses are noted in the right kidney. Further evaluation of renal masses with abdominal CT is then recommended.

Findings: Axial CT of the abdomen demonstrates solitary 1cm mass in right kidney, with an attenuation of -20 Hounsfield units.

Ddx: Renal cell carcinoma, Teratoma, Oncocytoma, Xanthogranulomatous pyelonephritis, Wilms tumor, Liposarcoma, Angiomyolipoma. (1)

Dxhow: The demonstration of fat by CT (-10 to -100 Hounsfield units) and ultrasound (echogenicity) is virtually diagnostic of angiomyolipoma. On rare occasions fat may be seen in other renal tumors, including RCC. (2)

Exam: Chem 7 reveals no electrolyte abnormalities and normal renal function.

No MeSH data available.
