OBJECTIVE: Bilateral endolymphatic sac tumors (ELSTs) are associated with von Hippel-Lindau disease and often underlie significant audiovestibular morbidity, including hearing loss.
PATIENT: This 44-year-old female von Hippel-Lindau disease patient presented with tinnitus, vertigo, and binaural hearing loss. Magnetic resonance and computed tomography imaging demonstrated bilateral ELSTs, and audiometry confirmed bilateral hearing loss.
INTERVENTION: The patient underwent staged resection of the ELSTs (left then right). After resection of the left ELST and during the same operation, a cochlear implant was placed.
MAIN OUTCOME MEASURES: Clinical, audiometric, and imaging data.
RESULTS: Postoperatively, the patient had resolution of tinnitus and vertigo with a significant implant-aided improvement in hearing.
CONCLUSION: Because of their unique anatomic and biologic features, resection of bilateral tumors and cochlear implantation in deaf ELST patients is a potential option to improve hearing and quality of life.
