Noncarboplatin-induced Sensorineural Hearing Loss in a Patient With an Intracranial Nongerminomatous Germ Cell Tumor

Treatment for intracranial germ cell tumors includes platinum-based chemotherapy and external beam radiation therapy, which are risk factors for hearing loss. In patients who experience significant sensorineural ototoxicity due to cochlear hair cell injury, dose reduction of chemotherapy may be necessary. This report describes an adolescent male, with excellent treatment response for an intracranial nongerminomatous germ cell tumor, who developed sensorineural hearing loss, which was central rather than cochlear in origin and unrelated to carboplatin. This patient highlights the need to carefully differentiate the type and etiology of sensorineural hearing loss in patients with brain tumors receiving ototoxic chemotherapy.
