Аннотация
OBJECTIVE: To describe the case of a true false-positive finding on magnetic resonance imaging, mimicking a vestibular schwannoma, and review the pertinent literature.
PATIENTS: The case of a single patient with a suspicion of a vestibular schwannoma.
INTERVENTION: A middle fossa craniotomy was performed for resection of the presumed schwannoma.
MAIN OUTCOME MEASURES: Intraoperative findings and postoperative magnetic resonance imaging (MRI).
RESULTS: : Intraoperative findings and a postoperative MRI confirm the absence of a neoplasm.
CONCLUSION: False-positive findings on MRI, though rare, do occur. The clinician should have a high index of suspicion and consider reimaging in some cases.
