Idiopathic omental hemorrhage: a case report and review of the literature.

backgroundA spontaneous rupture of an omental vessel can cause severe intraabdominal hemorrhage. We present a case of idiopathic omental hemorrhage caused by a vascular malformation. The literature is systematically reviewed. CASE PRESENTATION: A 65-year-old Iranian man was admitted to the emergency department for 10 days with abdominal pain. His medical history was not significant. Fever, vomiting, nausea, or anorexia were not reported. However, he was suffering from diaphoresis and malaise at the time. He did not smoke or drink alcohol. During physical examination, blood pressure was 82/60 mmHg with a temperature of 36.6 °C; heart rate was 96 beats/minute and respiratory rate was 18 breaths per/minute. An abdominal examination revealed mild tenderness in the periumblical. The focused assessment with sonography in trauma examination yielded positive results. The complete blood count showed 14 × 10

conclusionPresence of positive focused assessment with sonography in trauma, abdominal pain, imaging evidence of fluid accumulation, and a reduction in hemoglobin levels collectively indicate the likelihood of arteriovenous malformation occurrence. The treatment options include surgical intervention and transcatheter arterial embolization. Surgical intervention is recommended for subjects with hemodynamic instability, persistent hypotension and those whose diagnosis is unconfirmed.
