Massive, complex left ovarian mass containing peripheral enhancing lobulated soft tissue and fluid, and fat centrally with fat/fluid layer filling the majority of the abdominal cavity. The mass has ruptured along its superior margin where there is a greater amount of enhancing tissue, resulting in multiple implants along the anterior upper abdominal peritoneal lining and also along the lower liver margin and inferior spleen. Several other smaller implants within the peritoneal cavity. Mixed-density fluid with fluid fat with large volume ascites in the peritoneal cavity. The small bowel and upper abdominal vasculature are displaced and compressed in the upper abdomen. Mild right hydroureteronephrosis due to midureteral compression/obstruction, presumably related to peritoneal implants.
