Space occupying lesion involving the hepatic colonic flexure and the right side of the transverse colon. It is measuring about 5.1 x 6 x 5.1 cm in AP, SS & CC dimensions respectively. The lesion is encroaching upon and distending the colonic lumen still with no definite MDCT signs of proximal obstruction. Preserved pericolic fat. The mass showed an internal matrix of mainly fatty density with enhancing fine internal septae. Enhancing wall is also noted averaging 8 mm.

The liver showed tiny focal hypodense areas within segment VI and VIII, the largest is averaging 9 mm (small parenchymal cysts).

Scans through pelvis showed small uterine fibroids; the largest is fundo-posterior in location averaging 28 mm.
