Necrotic epiploic appendagitis: Ct findings and surgical timing

We present a surgical case of a necrotic epiploic appendage of a 37 yo man, that came to our Hospital for a doubt abdominal pain. Clinical and laboratory exam, such us ultrasonography can not orient to correct diagnosis. Only on CT images it is possible to diagnose epiploic appendagitis, in differential diagnosis with diverticulitis, especially when a pathognomonic sign is present, the “dot sign”. The diagnosis allows a correct medical or surgical management and avoids complicances.
