Teenager with abnormal pleural-based nodules on CXR who had sustained blunt abdominal trauma in the remote past

CXR and CT and Tc-99m sulfur colloid scan of diaphragmatic rupture
CXR AP shows a left-sided large pleural nodule just beneath the clavicle. Axial CT with contrast of the chest shows multiple pleural nodules throughout the left hemithorax and absence of the spleen. Tc-99m sulfur-colloid scan shows normal radiotracer uptake in the liver with no uptake in the region of the spleen (lower left), and nodular uptake throughout the left hemithorax (lower middle) and abdomen (lower right).

The diagnosis was diaphragmatic rupture and post-traumatic splenosis.
