Full Definition
Angiomyolipoma (AML) is a benign mesenchymal tumor of the kidney consisting of varying proportions of blood vessels, smooth muscle cells, and mature fat tissue. It may occur sporadically or in association with tuberous sclerosis complex. Large angiomyolipomas (>4 cm) carry risk of spontaneous hemorrhage and may require intervention. Treatment options include observation, embolization, or surgical resection depending on size, symptoms, and patient factors.
Usage
Usage note: Often abbreviated as AML in clinical notes, but spell out in formal reports.
