The arcuate line hernia is an, usually asymptomatic, ascending protrusion of intra peritoneal structure under the fold of Douglas, classified into three types depending on its severity and the degree of complication.We report a case of a 64-year-old Caucasian woman whose diagnosis of arcuate line hernia was initially missed at a computed tomography and diagnosed 3 weeks later on the repeat computed tomography scan when an intrahernian necrosis of the epiploic fat appeared.The present case discusses the classical anatomical and radiological features. The therapeutic approach is based on laparoscopic surgery.
