Small bowel obstruction with gradual gradation of bright oral contrast to darker intraluminal contents and fecalization leading to the transition point in the upper pelvis. The fecalized segment has mild wall thickening. The bowel transitions in the ileum and is associated with a lobulated partially calcified mesenteric mass which likely narrows the adjacent mesenteric veins; there is subtle increased enhancement of the bowel wall in this location which could represent the primary tumor. Small ascites. No adenopathy or definite liver lesions.
