The patient was a 32 year-old male with a past medical history significant for end stage liver disease secondary to severe alcoholism who was found with an altered mental status. In the emergency department, the patient divulged he had been throwing up blood clots in the preceding days. Shortly into his presentation he began throwing up voluminous bright red blood. Initial hemoglobin concentration was 2.8 mg/dL. CT scan of the abdomen revealed pneumatosis within the ascending colon, small bowel, and mesenteric veins. Despite massive transfusion efforts and two episodes of successful cardiac resuscitation the patient expired.
