A rare benign intrathoracic mass in a patient with history of rocket explosion.

Thoracic splenosis is rare benign condition that follows trauma leading to diaphragmatic injury. Most of the patients including ours present with a clear traumatic event leading to autotransplantation of spleen in thoracic cavity. Mostly diagnosed incidentally and we need to avoid unnecessary workup including radiological and invasive. It is a very important case which signifies importance of good history taking and initial imaging for making diagnosis and making our pulmonogist and internist aware of this diagnosis.
