The masses were predominantly cystic in those with rectosigmoid involvement, and predominantly solid in those with transverse colon or appendiceal involvement.
The location of the tumor was classified as proximal colon (cecum, ascending); transverse colon (hepatic flexure, transverse colon, splenic flexure); distal colon (descending and sigmoid colon); or rectosigmoid junction or rectum.
Subsequent colonoscopy revealed a fixed pelvis with rectosigmoid mucosal induration and thickening.
The patient was a 37-year-old white woman who previously had been diagnosed with stage IIIC low-grade serous carcinoma of the ovary, with significant peritoneal disease including extensive omental caking, tumor studding on the right and left hemi diaphragms, plaques on the surfaces of the liver and spleen, and tumor on the bladder and rectosigmoid serosa.
