The curious case of free-floating pelvic cysts.

The case of a healthy 33-year-old woman who underwent an elective caesarean section with incidental finding of small free-floating cysts within the pelvic peritoneum is presented. Gross examination could not identify the specimens. Histopathological investigation was necessary to classify the specimens as benign mesothelial cysts. The patient had no medical or surgical history and no other risk factors. The presented case is particularly interesting as the cysts were non-adherent to any pelvic or abdominal structure, as is commonly described. Similarly, there are few descriptions of mesothelial cyst diagnosis during pregnancy. 2014 BMJ Publishing Group Ltd.
