Abstract:Objective To evaluate the diagnosis value of CT for primary retroperitoneal lipoma. Methods CT findings in 7 cases of retroperitoneal lipoma with pathologically confirmed were retrospectively analyzed.Results Of the 7 cases,location was correct in 5 and qualitation was correct in 6.On plain scan:tumors were well-demarcated round or oval masses,homogeneous low density,-40—120Hu,and strip slightly high density can be seen in lesions,and calcification can be seen in 1 patient. After contrast medium administration in 4 of 7 cases,one patient showed patching enhancement and 3 cases showed punctiform or strip blood vessel.Conclusion Most of retroperitoneal lipoma have typical CT signs and it is not hard to diagnose them.
