A well defined, sizable, complex lesion having both solid and cystic components measuring 13 x 17 x 19 cm, is seen in the midline pelvis, likely arising from the right ovary. The lesion shows punctate calcifications and multiple enhancing septations as well as enhancing solid component. The lesion is displacing the uterus posteriorly, indenting the urinary bladder dome, is in close contact with small bowel loops and mildly compressing the right pelvic ureter. A well-defined cystic lesion measuring about 4.5 x 5.5 x 6.5 cm is seen in the left adnexa. A mural calcification is seen in it. No septations, soft tissue component or any enhancement is seen in it. No ascites, lymphadenopathy or pneumoperitoneum is seen. Mild right hydroureteronephrosis secondary to the mass effect over the right pelvic ureter. Mild left hydronephrosis with abrupt transition at pelviureteric junction, suggestive of partial pelviureteric junction obstruction. Morphology of the remaining abdominal viscera is unremarkable.
