Internal hernias are complete or partial protrusions of one or several viscera or tissues through an intraperitoneal orifice remaining in the abdominal cavity. Whatever the type or anatomical location may be, the seeming banality and lack of specific symptoms contrasts with the seriousness of complications such as strangulation followed by ischemia or intestinal necrosis. Delay in diagnosis can be shortened if these complications are kept in mind at diagnosis and if the imaging studies are illustrative. At the least doubt, surgery will correct the diagnosis and allow adapted treatment.
