[Giant perirenal lipoma. Apropos of a case]

Giant perirenal lipomas are rare pathological entities. Ultrasonographic, CT scan and angiographic findings are described for a case involving a 60 year old male patient. Once the diagnosis was made, primarily thanks to CT scans, the patient was followed-up for two years, until he decided to undergo surgery. Giant perirenal lipomas are one of the focal lipomatoses that can be followed-up with CT scans since surgery is rarely required, except in cases of giant tumors as in our patient (6 kg).
