Lipoleiomyoma of the peritoneum.
Lipoleiomyomas are rare, mixed mesenchymal tumors composed of adipose and smooth muscle cells. They usually arise from the uterus, with extrauterine tumors being extremely rare. The imaging and gross appearance is similar to other tumors with these constituents. Recognition of this rare and benign tumor is of great importance, in order to avoid erroneous diagnosis. We present a case of an extrauterine lipoleiomyoma with minimal amounts of fat, only identified by MRI. The extrauterine location was highlighted by multiplanar MRI, and the presence of a capsule suggested a benign tumor.
