Beschreibungen/Notizen
We present a case of large cystic vestibular schwannoma in a 60-year-old woman who complained of facial palsy and
tinnitus. Magnetic resonance images revealed signals of long T1 and T2, suggesting its cystic architectures. Enhanced
images showed marginal enhancement at the peripheral wall and multiple internal septa, but not at the intracanalicular
portion. An epidermoid cyst was presumed owing to its insinuating growth and lack of enhancement, but cystic
degeneration of vestibular schwannoma was confirmed histopathologically. She had an unremarkable postoperative
course. After thorough review of our case together with pertinent literatures, we emphasise the importance of
differential diagnosis of cystic lesions in the cerebellopontine angle. KCI Citation Count: 0
