Symptomatic Intrathoracic Splenosis More than Forty Years After a Gunshot Injury.

Thoracic splenosis is a rare heterotopic autotransplantation of the spleen into the thorax that occurs after trauma or surgery involving the spleen. It is most commonly found incidentally on imaging in the left hemithorax. To the best of our knowledge, only six symptomatic cases of thoracic splenosis have been described in the literature so far. We present a case of thoracic splenosis in a male with a remote history of a gunshot injury during childhood, who presented with chest pain and shortness of breath.
