Presentation
Abdominopelvic pain and progressive distension.
Patient Data
There is 185×105×175 mm unilocular cystic lesion with homogeneous internal density and a 20 mm enhancing mural nodule at the right anterior aspect; arising from the pelvis and extending superiorly until the level of the renal hilum. The left ovary cannot be differentiated from the mentioned cystic lesion. The uterus, bladder and right ovary are compressed by the lesion to the pelvic floor.
In addition, a 43×13×20 mm fat-containing mass is noted anterosuperior to the cystic lesion.
Small volume pelvic free fluid is also evident.
Case Discussion
The patient underwent surgical excision of the abdominopelvic mass and histopathology evaluation confirmed an ovarian collision tumor - in this case, the coexistence of teratoma and mucinous cystadenoma.
