Idiopathic segmental infarction of greater omentum in combination with acute appendicitis as a rare cause of acute abdomen

Idiopatic segmental infarction of greater omentum is an unusual cause of acute abdominal pain. Ethiology of this condition is not clearly elucidated and it´s clinical appearance often resembles acute appendicitis. There are some casereports describing coincidnece of both diagnosis. 43-year old male patient presented to I. surgical clinic of UNLP with right sided acute abdominal pain. Sonographic examination didn´t clearly show the apendical area but there was an increase of inflamatory markers and worsenig of pain localised to the right lower quadrant of the abdomen. Patient therefore underwent operation with the finding of infarcted part of greater omentum in size of 10 x 6 cm which was resected and appendicectomy was performed. Histological findings were necrotic changes of greater omentum and catharal appendicitis. Coincidence of segmental infarction of greater omentum and acute appendicitis is a rare cause of acute abdominal pain. Incidence is less then 0,1 % of patients who underwent an operation because of acute abdomen.
