چکیده
Santral sinir sisteminin en sık görülen ekstraksiyel tümörü olan menenjiyom %85-90 sıklıkla supratentorial yerleşim göstermekte olup, insidental olarak saptanır. Bu yazımızda, Acil Servis’e senkop ile başvuran 80 yaşındaki bir erkek hastayı sunmaktayız. Yapılan kranial bilgisayarlı tomografi (BT) ve magnetik rezonans görüntüleme (MRG) incelemelerinde posterior fossa orta hatta yerleşim gösteren ekstraaksiyel lezyon saptanmıştır. Lezyon 4. ventrikülü komprese edip, lateral ventriküllerde dilatasyona sebep olmaktaydı. Lezyonun total eksizyonu gerçekleştirilmiş olup, patolojik inceleme meningotelial (sinsitiyal) menenjiyom ile uyumlu gelmiştir. Bu vaka orta hat yerleşimli infratentorial lezyonların ayırıcı tanısında menejiyomun da düşünülmesi gerektiğini vurgulamaktadır. Abstract
