Angiomyolipomas are typically found in the kidney, but have also been commonly found in the liver and less commonly the ovary, fallopian tube, spermatic cord, palate, and colon. The Maclean imaging classification system for renal angiomyolipomas is based on the location of the angiomyolipoma within the kidney. [4]
angiomyolipoma, clear-cell "sugar" tumour (CCST), lymphangioleiomyomatosis, and, clear-cell myomelanocytic tumour of ligamentum teres/falciform ligament. abdominopelvic sarcoma of perivascular epitheloid cells [2] primary extrapulmonary "sugar" tumour [2] Thus, it has been advocated that the above could be classified PEComas.

Treatment of renal angiomyolipoma [ edit ] Renal angiomyolipomas (AMLs) may require embolization or cauterization for control of bleeding, a complication that is thought to be more common when tumor diameter exceeds 4 cm. [ 119 ] The extent of aneurysmal change may determine bleeding risk.
Removal of the kidney (nephrectomy) is strongly to be avoided. An asymptomatic angiomyolipoma that is growing larger than 3 cm is best treated with an mTOR inhibitor drug. Other renal complications spotted by imaging include polycystic kidney disease and renal cell carcinoma. Repeat chest HRCT in adult women every five to 10 years.
The renal condition should not be confused with other conditions which are Müllerian duct anomalies, such as Herlyn-Werner-Wunderlich syndrome. Some sources refer to double uters-hemivagina-renal agenesis as simply Wunderlich syndrome, but Herlyn-Werner-Wunderlich is a better term to distinguish the two.
The RENAL Nephrometry Scoring System is used to measure the complexity of kidney tumors for determining whether a renal mass is appropriate for partial or radical nephrectomy, and is estimated by CT scan as follows: [7] The nephrometery score takes into account the size of the tumor (Radius), how much of the tumor is inside or outside of the ...

This disorder presents with many benign hamartomatous tumors including angiofibromas, renal angiomyolipomas, and pulmonary lymphangiomyomatosis. Tuberin and hamartin inhibit the mTOR protein in normal cellular physiology. Inactivation of the TSC tumor suppressors causes an increase in mTOR activity.
