A 11- yea-old girl complained of bilateral hearing loss, and otologic examinations and mastoid X-ray films revealed space occupying lesions involving bilateral temporal bone and right external auditory canal. CT scans demonstrated “punched-out” radiolucent defects without sclerotic margins. T 1-weighted MR imaging demonstrated an intermediate signal intensity area. This was of intermediate to high intensity on T 2-weighted image.
The patient received mastoidectomy, and the histologic diagnosis of the mastoid tissue was eosinophilic granuloma. After the surgery, irradiation and chemotherapy were performed.
The literature was reviewed, and radiological diagnosis of the disease were described.
