Abstract:
Involvement of the temporal bone in histiocytosis X is seen in about one-third of the cases at onset, is bilateral in 31% of cases, and is often clinically silent. We report two cases of histiocytosis X with temporal bone involvement and emphasize the usefulness of computed tomography in detecting such a lesion, noting its extraskeletal extension, and following the course of the disease.
