目的 探讨脑结核瘤的CT诊断及鉴别诊断。材料和方法 本组6例脑结核瘤,男、女各3例、4例根据临床症状、体征、脑脊液生化及治疗后结果明确诊断,2例经用术后病理证实。同期胸片发现肺结核4例,一次性增强扫描2例,平扫后增强扫描4例。结果 6例脑结核瘤中,5例位于幕上,1例位于幕下。多数病变位于皮层或皮层下浅层,病变单发多发各3例。CT平扫病变为低密度1例,结节状、环状稍高密度灶3例。增强后结节状强化3例,环状强化2例,结节状并环状强化1例。结论 CT检查对脑结核瘤的诊断及对指导临床治疗均具有重要参考价值。
Objective To investigate the CT diagnosis and differential diagnosis of brain tuberculoma. Materials and methods The group of 6 cases of brain tuberculoma, male and female in 3 cases, 4 cases based on clinical symptoms, signs, cerebrospinal fluid biochemical and post-treatment results of a clear diagnosis, 2 cases were confirmed by pathology. In the same period, 4 cases of pulmonary tuberculosis were found in chest radiograph, 2 cases were one-time enhanced scan and 4 cases were enhanced scan after plain scan. Results In 6 cases of brain tuberculoma, 5 cases were located on the screen and 1 case was located under the screen. Most of the lesion is located in the cortex or subcortical shallow, single lesions in each of the three cases. CT plain lesions in 1 case of low density, nodular, ring slightly higher density in 3 cases. Three cases showed enhancement of nodular enhancement, two cases of annular enhancement and one case of nodular and annular enhancement. Conclusion CT examination of brain tuberculosis diagnosis and guidance of clinical treatment are of important reference value.
