摘    要:目的探讨脑脓肿CT表现与临床应用价值。方法总结10年来经CT诊断,临床治疗或手术病理证实21例脑脓肿,所有病例经CT平扫加增强检查。16例非手术治疗,5例手术治疗。均行CT复查,最多复查5次。结果21例脑脓肿中,单发17例,多发4例。CT平扫表现为单个或多个低密度灶或囊状病灶。增强后仅2个病灶未见环形强化,其余病灶周围均见明显环状强化。脑灰白质交界处脓肿,多数近脑室侧脓肿壁较薄。17例非手术治疗复查CT,好转后表现为脓腔缩小,最后脓腔消失。4例手术穿刺引流复查,见脓腔缩小,直至完全消失。结论脑脓肿CT表现有一定特征性,是诊断脑脓肿首选方法,对治疗方案选择和预后评价具有重要意义。

Abstract:Objective To probe manifestations of brain abscess on CT and clinical value of CT in brain abscess. Methods 21 cases that had been confirmed as brain abscess in the past decade either by CT imaging or clinical data or pathological methods underwent plain scan and enhanced scan using CT. 16 cases were treated by non-operation methods and 5 underwent operation. All cases were followed-up by CT. The most frequent case underwent 5 times of CT scan. Results There were 17 cases that had single lesions and 4 had multiple lesions displaying single or multiple low density focus or cyst-like lesions. After enhanced scanning, only 2 lesions did not show ring-shaped enhancement, the others were obviously enhanced with ring shape. Walls of abscess lesions that were located in areas bordering grey and white matter and areas that neighbored ventricles were relatively thin. Among 17 cases that were treated with non-operation methods displayed on CT narrowed cavity and disappeared finally. 4 cases that underwent puncture and drainage displayed on CT narrowed cavity and disappeared finally. Conclusion CT has characteristic manifestations on brain abscess. It should be the first choice for the diagnosie. It has value to selecte treatment methods and evaluate prognosis for brain abscess.
Keywords:Brain abscess X-ray computed Clinical value
