(A) Ultrasonography of the pelvis shows a multilocular cystic mass in the pelvic cavity. (B) Magnetic resonance imaging shows small multiple nodules about 1 cm in size with low signal intensity in the anterior and posterior uterine wall on T2-weighted images.

Ultrasonography (Fig. 1A) and computed tomography (CT) of the pelvis revealed a multilocular cystic mass in the pelvic cavity. Magnetic resonance imaging (MRI) revealed small multiple nodules about 1 cm in size with low signal intensity in the anterior and posterior uterine wall on T2-weighted images and multiple nodules with 4.6 cm and 2.8 cm sized heterogeneous signal intensity in the pelvic cavity on T1-weighted images (Fig. 1B).
(A) On laparoscopy, multiple grapelike clusters of cysts appear to originate from the peritoneum. (B) multiple cysts are attached to the uterus and both adnexa. (C) Additional small cysts are seen on the omentum, small bowel mesentery, and appendix. (D) Calretinin immunohistochemical staining (x100) reveals a positive reaction.

During laparoscopy, we observed multiple grapelike clusters of cysts within the pelvic cavity (Fig. 2A). The cysts appeared to originate from the peritoneum and attached to the uterus and both adnexa (Fig. 2B). Additional small cysts were found on the omentum, small bowel mesentery, and appendix (Fig. 2C). The lining cells were immunohistochemically reactive for pan-cytokeratin and calretinin (Fig. 2D).
