CT and MR Findings of Primary Hepatic Leiomyosarcoma : ACaseReport

We describe the CT and MR findings of primary leiomyosarcoma of the liver and review the radiological findings of the previous reports of this disease. A 35-year-old woman presented with discomfort in the right upper quadrant of the abdomen. On contrast-enhanced CT, a well circumscribed and lobulated, homogeneously hypoattenuating solid mass with slight peripheral enhancement was identified in the caudate lobe of the liver. On spin-echo MR imaging, the tumor showed homogeneous hypointensity on Tl-weighted images and hyperintensity on T2-weighted images. Contrast-enhanced Tl-weighted imaging showed markedly heterogeneous enhancement throughout the mass.
