title: Atypical meningioma of sylvian fissure with a 20-year history: a rare case report.
abstract: Atypical meningiomas of sylvian fissure are extremely rare. We reported a case of sylvian fissure atypical meningioma with a 20-year history. The tumor was excised subtotally, thereafter a postoperative radiation therapy was done. The patient had a favorable outcome during the two-year follow-up. The possible pathogenesis of this case was hypothesized and analyzed in this article.
