Angiomyolipom der Niere

Upper abdominal ultrasound imaging in a 63-year-old woman who had been hypertensive for ten years revealed a tumour at the lower pole of the left kidney. It protruded from the renal surface and gave dense echoes, suggestive more of an angiomyolipoma than a hypernephroma. The former diagnosis was reenforced by the angiographic appearance and confirmed by biopsy at the time of surgery. Nephrectomy was performed and the postoperative course was without complication.
