隐匿性脑血管畸形

Occult Cerebral Vascular Malformation

本文报告了12例隐匿性脑血管畸形。此病是指一组直径小于2～3cm 的血管畸形,其分布在幕上、下几乎相等,可发生于脑的任何部位,具有较高出血和再次出血的倾向。CT 检查无特征性表现,全脑血管造影可发现部分病变,磁共振成像有其特征性表现。本病在未出血前诊断困难,中、青年以自发性脑内出血为首发症状,或有癫痫病史是诊断的重要线索。对出血后的手术治疗应采取积极态度,清除血肿和发现病变。

12 cases of cryptic cerebral vascular malformation were reported.Cryptic vascularmalformation of the brain was defined as a cluster of vascular malformation withits diameter less than 2～3 cm.The morbidities in supratentorium and inferotentorium were nearly equal.This kind of malformation could be located anywhere in the brainand had a high tendency of hemorrhage and recurrent hemorrhage.CT scan did notshow characteristic presentations.Cerebral angiography might reveal part of the les-ion and MRI had its own characteristic presentations.The diagnosis of the diseasebefore episode hemorrhage was difficult.Spontaneous parenchymal hemorrhage wasgenerally the first symptom in young and middle aged patients.Epilepsy history wasan important clue for diagnosis.Active surgical interference was advocated forpost-hemorrhage patients.
