Summary
A calcified kidney angiomyolipoma was found incidentally. Imaging could not rule out cancer due to fat and calcification, but biopsy confirmed angiomyolipoma, suggesting biopsy before kidney removal.
Area of Science:
- Nephrology
- Radiology
- Pathology
Background:
- Renal masses require accurate diagnosis to guide treatment.
- Imaging characteristics like calcification and fat can complicate diagnosis.
Observation:
- A calcified angiomyolipoma of the kidney was incidentally discovered on abdominal computed tomography.
- Intratumoral calcification and macroscopic fat within the renal mass raised suspicion for renal cell carcinoma.
Findings:
- Pathological study following biopsy confirmed the diagnosis of angiomyolipoma.
- The presence of macroscopic fat and calcification did not exclude benign angiomyolipoma.
Implications:
- Renal mass biopsy may be a valuable diagnostic tool.
- Biopsy should be considered for renal masses with fat and calcification before proceeding with nephrectomy.

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
