Eosinophilic granuloma of the temporal bone.

Involvement of the temporal bone by eosinophilic granuloma is rare. Four cases are presented here and the pertinant literature is reviewed. This disease must be kept in mind by the otolaryngologist because of the diagnostic and therapeutic problems that may arise. Direct injection of methyl-prednisolone sodium succinate is suggested as a treatment of eosinophilic granuloma in the temporal bone.
