Unexpected finding of splenic peliosis in a traumatic spleen in a patient with cleidocranial dysplasia.

We present a case of traumatic rupture of the spleen in a man with cleidocranial dysplasia. The computed tomography imaging showed multiple low-grade lacerations of the spleen which initially led to conservative patient management. However, with clinical deterioration, the patient underwent an emergent splenectomy. Post-operative histology revealed splenic peliosis with multiple lacerations. The radiological and surgical management of post-traumatic splenic peliosis may differ from those with an otherwise normal spleen.
