CAVERNOMAS

Abstract

Corebral vascular malformations have traditionally been divided into (Gür categories : arterioyenous, venous, cavernous and capillay telengiectases, A cavernous malformation (cavernous angioma) is one of four commonly occurring types of cerebral vazcular malformations. It is defined as an abnormaliy enlarged collection of vascular channels without brain parenchyma, intervening. These malformations are rare, The familial incidence of these maltormations has been previous described. Magnetic resonance imaging is the radiographic diagnostic tecbnigus of choice in the detection and follow of these lesions. İn ihis article, 3 cases of histopathologically verifed cerebral cavernous angiomas have been reporusd. Their presenting signs, symptoms together wiih ihe radiological and histopathological features of the disorder have been discussed. Key Words : Cerebral vascular malformations, Cavernous angiom, Magnetic resonance imaging, Venous Angiom

KAVERNOMLAR

Abstract

ebral vasküler malformasyonlar genellikle dört tip olarak tanımlanmışlardır. Bunlar venöz malformasyonlar, kavernöz anjiomlar, kapiller telenjiektaziler ve arteriovenöz malformasyonlardır. Kavernöz anjiomlar, sinüzoidal damarlar arasında beyin parankiması içermiyen, patolojik olarak genişlemiş vasküler kanallardan oluşmaktadır. Nadir olarak görülürler ve aile öyküsü tanımlanmıştır. Magnetik Rezonans Görüntüleme (MEG) bu lezyonların teşhis ve takibinde seçilmesi gereken radyolojik bir tetkiktir. Bu makalede, histolojik olarak teşhis edilen kavernöz anjiom'lu üç olgunun klinik, radyolojik ve histopatolojik özellikleri literatür gözden geçirilerek sunulmuştur. Anahtar Kelimeler : Serebral vasküler malformasyonlar, Kavernöz anjiom, Magnetik Rezonans Görüntüleme, Venöz Anjiom
