Spleen scintigraphy

Scintigraphy shows a radiocolloid uptake near the lingula and the left pulmonary hilum, compatible with intrathoracic ectopic splenic tissue.

CT-scan shows no obvious anomaly at the site of radio-colloid uptake.

Case Discussion

Intrathoracic splenosis is a rare condition that usually occurs following trauma. It usually occurs with diaphragm tears. The newly implanted splenule will become vascularized by adjacent pulmonary vessels.
