title: A 45-year-old woman with reversible bilateral hearing loss.
abstract: A 45-year-old woman complained of a progressive 2-month history of bilateral hearing impairment and diplopia on upward gaze. She had a history of a recurrent pineal region ganglioglioma with repeated tumor excision, adjuvant radiotherapy, and a ventriculo-peritoneal shunt performed 12 years prior. Subsequent imaging studies 6 years ago showed a pineal region cyst with progressive increase in size and a Rickham reservoir (Codman; Johnson & Johnson, Raynham, MA) was placed for percutaneous cyst fluid aspiration. The size of the cystic lesion remained static upon follow-up CT scans for several years.
