Intramedullary osteosclerosis: An incidental sclerotic lesion in a trauma patient

Intramedullary osteosclerosis, a rare entity, is usually diagnosed after the exclusion of more sinister etiologies. It typically affects the lower extremity and is more common in females. While the lesion may be discovered incidentally during imaging, presenting symptoms may include pain in the affected bone that is exacerbated with physical activity. Laboratory values are normal, and the lesion is not associated with familial skeletal dysplasias. Common imaging findings include a mono-ostotic or polyostotic sclerotic lesion that lacks a periosteal reaction, soft-tissue component, and nidus. We present a case of intramedullary osteosclerosis that was incidentally discovered in a trauma patient.
