Abstract

Mesenteric cysts are usually not considered in the differential diagnosis of pelvic cystic masses. The more common considerations for pelvic cystic masses include ovarian cysts such as, endometrioma, dermoid cyst, and other neoplasm. Here we report a case of 15-year-old girl with pelvic cystic mass; it was initially thought to be ovarian endometrioma, but the operative and histologic findings revealed a mesenteric cyst.

Figure

• 

  Fig. 1 Computed tomography images showed a unilocular shaped cystic mass without fat and/or calcification. Its origin was supposed to be right ovary.

• 

  Fig. 2 Trans-abdominal ultrasonogram showed homogeneously hypoechoic feature of cystic mass.

• 

  Fig. 3 Intra-operative findings. (A) The origin of cystic mass was mesentery. (B) Both ovaries were intact.

• 

  Fig. 4 Microphotographs. (A) Cyst wall on low grade magnification. (B-D) Lined by respiratory epithelium (black arrow and C) and focal squamous epithelium (gray arrow) with glandular structure (white arrow and D). Disoriented smooth muscle wall was also observed (star). (A, ×10; B-D, ×200, H&E stain).
