CTICasesThoracic Splenosis
Imaging findings
Chest radiograph and CT show a large diaphragmatic hernia post remote motor vehicle crash. Multiple hyper-enhancing nodules are present along the pleural surfaces and within the chest wall. The spleen is absent.
Key takeaways
Splenosis is the autotransplantation and growth of splenic tissue following splenic trauma and diaphragmatic rupture. It can locate in the pleural space or chest wall, presenting as vascular nodules that avidly enhance on arterial phase and should not be mistaken for metastases.
