Primary Hydatid Cyst in the Rectovesical Pouch

Abstract

Cyst hydatid disease is a parasitic zoonosis caused by the larvae of the tapeworm belonging to the Echinococcus species. While hydatid disease can affect almost any part of the human body, the liver and lung are the two organs where the disease is most frequently detected. Peritoneal involvement may develop following a hepatic hydatid cyst surgery or as a result of spontaneous micro-ruptures of the hepatic hydatid cyst into the peritoneal cavity. However, with only a few reported cases, primary hydatid cyst in the rectovesical pouch is extremely rare, even in endemic regions. In this study, a 37-year-old man admitted to the emergency department with frequency and nocturia diagnosed as having a primary hydatid cyst in the rectovesical pouch.
