Primary mesenteric hydatid cyst.

ABSTRACT

Hydatid disease mostly caused by Echinococcus granulosus is a common parasitic infestation of the liver. Most common sites are liver (70%) and lungs (25%). Intraperitoneal hydatid cyst is found in 13% and it is usually secondary to rupture of primary hepatic cyst. Primary intraperitoeal hydatid cyst is rare (2%). Primary hydatid cyst in mesentery is very rare. In this article, the author presents a case of primary mesenteric hydatid cyst with chronic pain in lower abdomen.
