Idiopathic segmental infraction of the greater omentum (ISIGO) is a rare cause of acute abdomen. One of the main symptoms is right-side abdominal pain, while its etiology is still unclear. Until now, ISIGO simultaneously with spontaneous splenic rupture (SSR) has not been reported. Here, we presented a case of a 35-year old man, who was admitted with an acute abdomen, and the clinical diagnosis was ISIGO with SSR. He had a significant previous medical history of the vein thrombosis of lower limbs. Partial omental resection and splenectomy were performed, and the postoperative recovery of the patient was excellent. We also highlighted several possible theories to explain the etiology of the ISIGO, and emphasized that surgical methods, including laparoscopic surgery and laparotomy, are still the best way to treat the ISIGO at the emergency condition.
