A Case Report of an Abdominal Pain: Spontaneous Splenic Hematoma with Unknown Etiology

Splenic hematoma is one of the common complications following abdominal blunt trauma, but non-traumatic splenic hematomas are not common and occurs in some cases, such as hematologic disorders and/or infections. Idiopathic splenic hematoma that occurs spontaneously without an underlying disease, is a rare occurrence, which its diagnosis needs strong clinical suspicion. Case report: The patient was a young man who referred to the emergency department with sustained lower abdominal pain during the past day. The pain aggravated by bending and was worsened by lying down. The patient reported no specific concomitant symptoms. His past medical history and drug history were negative. Chest x-ray and laboratory tests did not show any abnormal finding. In the upright radiograph of the abdomen, the shadow of the spleen seemed larger than the normal size. Abdominal sonography showed extensive subcutaneous hematoma of the spleen, which was confirmed by CT scan. The patient was under observation in the intensive care unit for 48 hours, that due to the pain intensification of the candidate, the splenectomy was performed. Pathologic study of splenic tissue was normal and he discharged within one week with satisfactory general health condition.
