Langerhans' cell histiocytosis of the temporal bone in pediatric patients: imaging and follow-up.
The purpose of this study was to review the initial clinical and radiologic manifestations and the follow-up of pediatric patients with Langerhans' cell histiocytosis affecting the temporal bone. ⋯ In Langerhans' cell histiocytosis, involvement of the temporal bone is usually seen on radiographs as extensive lytic lesions associated with soft-tissue masses. The lesions that remit show early disappearance of the soft-tissue mass, followed by reossification and remodeling of the involved bone. Patients with limited initial involvement of the temporal bone have a better prognosis on long-term follow-up than do patients with the multisystemic form.
