A large vestibular schwannoma after recent negative MRI: A case report.

Vestibular schwannomas are, on average, slowly growing tumors that may remain quiescent for some time before manifesting themselves symptomatically or being found incidentally on imaging. We describe a case of a vestibular schwannoma that grew rapidly and to a large size in a patient who had undergone negative imaging 5 years earlier for unrelated issues. This case highlights the importance of repeat imaging in patients with symptoms concerning for vestibular schwannoma who might have previously undergone negative scans.
