Sonography showed acoustic shadowing distal to the central region of the AML behind a hyperechoic cholesterol, which was hypoattenuating on CT with no contrast enhancement. Microscopic examination confirmed that this central area was a cholesterol granuloma. The patient was treated successfully with radical nephrectomy.4enjournal article
