A rare differential diagnosis of gluteal mass

Abstract

Fat necrosis is an inflammatory process of fat folloing an insult to the adipose tissue. It is more common in the body region here there is high adipose tissue. It can present ith cellulitis, skin necrosis, discharging ounds, and mass. Carcinoma is one of the differential diagnoses of fat necrosis. Our case is presented ith a gluteal mass hich as diagnosed as a hydatid cyst, based on the imaging. Sometimes, imaging fails to identify traumatic fat necrosis, particularly if it is associated ith a capsule ith multiple fat lobules. Postoperative history confirms the encapsulated type of fat necrosis ith fat lobules. Encapsulated traumatic fat necrosis should be considered one of the differential diagnoses of hydatid cyst.
