脑内小脓肿

SMALL INTRACEREBRAL ABSCESS

报告6例脑内小脓肿(直径在1.5cm以下),不同于一般脑脓肿。指出其临床特点为:(1)病前无明显的感染史或外伤史。(2)临床表现多以癫痫为首发症状,且多为局灶性癫痫发作。(3)CT扫描具有特征性改变,是诊断本病的可靠方法。本组6例中2例非手术治疗,4例手术治疗,其中1例手术失败,3例脓肿摘除,作者认为术中准确定位是手术能否成功和避免手术并发症的关键,作者采用自制多孔测量板术依据病变在CT扫描层面和前后左右的距离进行定位,3例手术均获得成功。并对术后癫痫发作加以讨论。

Small intracerebral abscess, less than 1.5 cm in diameter, is a disease distinct from the ordinary brain abscess. Clinically, it is characterized by sudden onset of focal epilepsy, negative history of Previous infection or brain trauma and characteristic findings in CT.The Present series consisted of 6 cases, 2 treated conservetively and 4 oPereted on. The operation failed in the 1st case but succeeded in removing the well defined abscess in the other 3 cases. The key to success of the surgery lies in the accuracy in locating the abscess, for this purpose our self-made multiholed measuring board proved to be rather useful. The postoperative sequelae, such as ePilepsy and paralysis, are discussed and suggestions for improving the surgical procedure are Put forward.
