Sigmoid necrosis due to ischemic colitis induced by the presence of retroperitoneal hematoma is a rare situation, especially due to the presence of the particular vascularization of this intestinal segment, characterized by the presence of the collateral blood supply. However, in a small number of cases, sigmoid necrosis might develop. We present the case of a 56-year-old patient who has been initially submitted to surgery for pre-irradiated stage IIB cervical cancer. Postoperatively, the patient developed a deep venous thrombosis which necessitated administration of low molecular weight anticoagulants. Two weeks later the patient presented in emergency for diffuse abdominal pain and rectal bleeding. She was diagnosed with a retroperitoneal hematoma and sigmoid necrosis, so a sigmoidectomy with colo-rectal anastomosis was performed.
