Large hypodense soft tissue mass with cystic attenuation occupying the mid to lower abdomen. Presence of fat component (predominantly at posterior aspect), enhancing internal septations (lower aspect) and traversing vessels within. No calcifications. Anteriorly, this mass stretches and abuts the recti muscles with loss of clear fat plane in between. Inferiorly, it compresses onto the urinary bladder. It extends to the recto-vesicle pouch with no clear fat plane with the rectosigmoid colon. The mass displaces the small bowels superiorly. The descending colon is compressed posteriorly. The inferior vena cava is also compressed, however, still remains patent. The overlying peritoneum is not thickened. No peritoneal nodules seen.
Enlarged right iliac node.
Impression: Large intraperitoneal mass with fatty component, enhancing septations, local infiltration and right iliac lymphadenopathy, highly suspicious of malignancy. Liposarcoma has to be considered.
