ct

Likely arising from the right ovary, there is a cystic mass measuring 14.3 x 33.1 x 35.9 cm (AP TR CC), occupying the majority of the abdomen/pelvis. The cystic mass is homogenous in attenuation with <5 HU. There is a thin, well-circumscribed wall, without evidence of internal enhancing septations, thickened mural nodules, or calcifications. There is a small amount of right ovarian tissue seen laterally. This lesion results in significant mass effect on the abdominal and pelvic structures, with compression of the bladder, and displacement of the bowel and pancreas.

No peritoneal soft tissue lesions or free fluid are identified. The left ovary is normal.

Thorax: There is a retroesophageal course of the right subclavian artery.

Case Discussion

This is a case of a pathologically confirmed serous cystadenoma. Gross pathologic analysis of the resected ovarian cyst revealed a tan-pink serosal surface around a large cyst with brown-tinged fluid. Aspiration of the cystic fluid revealed histiocytes and inflammatory cells without an epithelial component. The patient did well post-operatively without recurrence of the cyst.
