A Rare Case of Diffuse Hemangiomatosis of the Spleen with Sp
Splenic hemangiomas are the most common primary neoplasm of the spleen. Usually they are asymptomatic incidental findings and can easily be diagnosed with computed tomography (CT) or magnetic resonance imaging (MRI), due to their typical contrast enhancement. As benign tumours, splenic hemangiomas usually do not require any treatment. Rarely, especially if localized under the splenic capsule, splenic hemangiomas can cause subcapsular hematomas, complete splenic rupture, and consequently severe internal bleeding. A diffuse splenic hemangiomatosis, which forms multiple tumours within the whole spleen, is very rare and can cause spontaneous splenic rupture.

Case Representation
A 68-year-old man underwent an open aortic valve replacement because of severe aortic valve stenosis. The day after the open-heart-operation a revision thoracotomy was needed, because of postoperative acute thoracic bleeding, and during the procedure a cardiopulmonary resuscitation was performed.Three days after first surgery the patient became again hemodynamically unstable and presented signs of hemorrhagic shock. Sonography demonstrated an enlargement of the spleen and free fluid in the peritoneal space. Pericardial and pleural effusions could be excluded.
