Imaging of leiomyosarcoma. a An 85-year-old man who presented with abdominal pain. CT shows a large heterogeneous left sided retroperitoneal mass (arrow) with central low attenuation in keeping with necrosis. b A 64-year-old woman presenting with early satiety. CT shows a large heterogeneous in the right abdomen, which is displacing the overlying liver. c, d A 60-year-old woman with IVC leiomyosarcoma. Coronal contrast-enhanced CT image (c) shows a large mass within the IVC (arrow). Axial T1-weighted image post gadolinium in the same patient (d) shows a heterogeneous enhancing mass centred on the IVC (arrow) and extending beyond the IVC into the paracaval location. There is moderate degree right-sided hydronephrosis secondary to the mass. Liver metastasis is noted in segment III of the liver (arrowhead). e A 77-year-old woman with IVC leiomyosarcoma extending to left renal vein. Coronal CT shows a heterogeneous enhancing mass filling the IVC and extending into the left renal vein (arrow)
