Chronic spontaneous idiopathic spleen hematoma presenting as a large cystic tumor: a case report with review of the literature.

Spontaneous idiopathic splenic hematomas occur very rare. Hematomas of the spleen are usually associated with trauma, or infectious, neoplastic, or hematologic diseases. They present a diagnostic challenge as they can be easily confused with other more common entities. We report a case of atraumatic idiopathic splenic hematoma in a patient with no underlying systemic or local disease and discuss the approach to diagnosis and treatment.
