Small angiomyolipoma in the left kidney

Welcome to e health forum.

Angiomyolipoma (AML) is a benign renal neoplasm composed of fat, vascular, and smooth muscle elements. 80% of such tumors are due to sporadic genetic mutations (Isolated AML).

Current management options include observation, embolization, and partial or total nephrectomy. Recommendations for treatment are usually based on the patient's symptoms or the size of the lesion.

Small asymptomatic lesions (< 4 cm) tend to remain asymptomatic, stable but should be periodically evaluated. They usually need no interventions.

Medium-sized lesions (4-8 cm) have the most variable behavior and have a less predictable natural history. These lesions are followed closely with serial imaging studies, and if significant changes in size or symptoms are noted, or risk for flank trauma is high, elective intervention is done.

Large asymptomatic angiomyolipomas (Tumors > 8 cm) will most likely become symptomatic and should be treated electively prior to the development of symptoms and potential complications.

Hence in your wife's case, the tumor appears to be a medium sized, and hence regular monitoring the growth of the tumor with a CT scan every 3-6 months.

Surgical removal might be sought, if the tumor enlarges more, causing any symptoms like pain or bleeding in the urine.

In case of any doubts, you may consult with your treating doctors who can provide more information and proper advice.

I hope this helps.
