Lesser omental panniculitis: a possible cause of acute abdomen. We encountered a case of panniculitis of the lesser omentum in 2018 after a long time since our first case report in 2007. We reviewed previously reported three cases of lesser omental panniculitis including our first case to investigate its clinical characteristics. Total four cases were relatively young with mean age of 30, and had common chief complaint of considerable epigastric pain and tenderness. Blood test showed increase in the white blood cell, C-reactive protein, or erythrocyte sedimentation rate. Computed tomography revealed mass like change in the fat tissue outside of the lesser curvature of the stomach. Histopathological diagnosis was made in one operated patient. Other three patients were treated conservatively, and progressed well. Lesser omental panniculitis is a possible cause of acute abdomen, which shows characteristic images of computed tomography and probably good progress by conservative treatment.
