Uterine lipoleiomyoma: MRI, CT and ultrasonographic findings

MRI, CT and ultrasonographic findings in lipoleiomyoma of the uterus are reported. A 73-year-old woman presented with a palpable mass in the lower abdomen. T2 weighted MR images showed an 8 x 5 cm exophytic well defined hyperintense mass of the uterine body. Fat content within the tumour was confirmed because of evident chemical shift artefact. Microscopically, the tumour proved to be lipoleiomyoma consisting of smooth muscle cells and mature adipose tissue. Five cases have been reported in the imaging literature, and the presence of fat within a uterine mass on CT or MRI is diagnostic of lipoleiomyoma.
