CTICasesSplenosis of the Left Thorax
Imaging findings
CT and sulfur colloid scan in a male with a history of a gunshot wound and splenectomy show extensive multinodular left-sided pleural masses that light up on splenic scintigraphy, representing splenosis that herniated through a diaphragmatic tear.
Key takeaways
Thoracic splenosis is a rare condition where autotransplanted splenic tissue seeds the pleural space following traumatic diaphragmatic rupture and splenic injury. Heat-damaged red blood cell or sulfur colloid scans are diagnostic, avoiding biopsy of these vascular lesions.
