This 37 y/o female presented to the ER with abdominal pain. She had a history of abdominal surgery for an accidental gun shot wound several years ago. She was afebrile and her abdomen was soft and without rebound. An acute abdominal series demonstrated a normal gas pattern, an absent splenic shadow, multiple surgical clips, and a subtle left lung lesion. A chest CT pre & post contrast was subsequently performed. The left mid lung field lesion is noted to be posterior, pleural based and mildly enhancing. The spleen is absent and there is some enhancing tissue in the left lower posterior thoracic subcutaneous fat. Intrathoracic splenosis from the prior gun shot injury was suspected and confirmed with Tc99m sulfur colloid nuclear scintigraphy.
