Tératomes parasitiques péritonéaux et péritonites chimiques dermoïdes

Abstract

Chemical peritonitis occurs following intraperitoneal rupture of a mature ovarian dermoid. Rupture may be acute and spontaneous, typically during pregnancy, or iatrogenic. Low grade ruptures lead to parasitic peritoneal dermoid cysts, usually involving the greater omentum, cul-de-sac of Douglas and perihepatic region. Radiologists should be familiar with their appearance to correctly diagnose the condition and not mistake the disease for peritoneal carcinomatosis.
