False-positive magnetic resonance imaging in the diagnosis of vestibular schwannoma.
OBJECTIVE
To describe the case of a true false-positive finding on magnetic resonance imaging, mimicking a vestibular schwannoma, and review the pertinent literature.


METHODS
The case of a single patient with a suspicion of a vestibular schwannoma.


METHODS
A middle fossa craniotomy was performed for resection of the presumed schwannoma.


METHODS
Intraoperative findings and postoperative magnetic resonance imaging (MRI).


RESULTS
: Intraoperative findings and a postoperative MRI confirm the absence of a neoplasm.


CONCLUSIONS
False-positive findings on MRI, though rare, do occur. The clinician should have a high index of suspicion and consider reimaging in some cases.
