Background . Syncope is common in emergency medicine, but only a minority of syncopes is caused by hemorrhage. Liver hemangioma is the most frequent benign liver tumor, and they rarely lead to symptoms or complications. Case Presentation . We describe the case of an 81‐year‐old man with hemorrhagic shock due to an atraumatic rupture of a hepatic hemangioma while on oral anticoagulation. The patient presented to the emergency department after three episodes of syncope before admission, nausea, vomiting, mild epigastric abdominal pain, but with clinical signs of peritonitis. On admission, the patient had a mild tachycardia with a heart rate of 107/min and a blood pressure of 102/83 mmHg. Initial hemoglobin was 122 g/L, and lactate was slightly elevated (2.5 mmol/L). Bedside sonography revealed free intraabdominal fluid. The subsequent computed tomography showed a ruptured hemangioma of the liver with ongoing hemorrhage. After the CT scan, the patient became increasingly tachycardic and the blood pressure dropped to 94/62 mmHg. After administration of blood products and intravenous fluids, the patient responded with improved hemodynamics and was transferred to angiology for emergency embolization. After the intervention, the patient spent two days in the intermediate care unit and was discharged after 10 days of hospitalization. Conclusion . Atraumatic rupture of a hemangioma with consecutive hemorrhagic shock is extremely rare. In selected cases of spontaneously ruptured hemangiomas with hemoperitoneum, endovascular embolization can be an alternative to surgery. Furthermore, this case emphasizes the importance of sonographic examination as an additional diagnostic tool in syncope and concomitant abdominal pain.
