A rare case of eosinophilic granuloma of the mandibular condyle in a 53-year-old woman is presented. The patient was referred to our department because of pain following discomfortin the left preauricular region. She had limitation of mouth opening without swelling or noise in the temporomandibular joint region. A panoramic radiograph showed an ill-defined lytic lesion occupying the left condyle. On MR imaging, the lesion was depicted as low signal intensity on T 1 -weighted images and as high signal intensity on T 2-weighted images and involved the condyle and lateral pterygoid muscle. The excised specimen obtained from the condyle was histologically diagnosed as eosinophilic granuloma. Mouth opening difficulty and pain resolved postoperatively. The condyle was regenerated 1 year after surgery, andthere has been no evidence of recurrence for 3 years 10 months.
