目的 :总结我院收治的 82例颅内转移患者的临床资料 ,进行CT诊断与分析 ;方法 :全部 82例患者使用美国Picrer第四代全身CT机检查 ,以OM线为基线连续向上扫描 9～ 11层 ,层厚 10mm ,层间距 10mm ,其中 6 3例为平扫加增强扫描 ,12例仅为平扫 ,7例为直接增强扫描 ,CT扫描表现如下 ;结果 :平扫时呈低密度 18例 ,其中 12例为肺癌 ,2例为肝癌 ,3例为乳腺癌 ,1例为肾癌 ,呈等密度 15例 ,其中 14例为肺癌 ,1例为食管癌 ,呈结节状稍高密度者 39例 ,其中 2 8例为肺癌 ,5例为食管癌 ,2例为前列腺癌 ,1例甲状腺癌 ,2例为绒癌 ,平扫时密度不均匀者 3例 ,病灶周围有明显水肿者 79例 ,3例无水肿 ,仅表现为稍高密度结节影 ,其中轻度水肿 15例 ,中度水肿 7例 ,重度水肿 5 3例 ,大多数病灶占位效应明显 ,72例具有侧脑室或三脑室受压变形 ,70例中线结构移位明显 ,增强扫描肿瘤形态显示清楚 ,病灶呈环状强化 2 2例 ,结节状或斑片状强化 2 3例 ,环状与结节状强化并存者 18例 ,7例呈不规则形强化 ;结论 :对于具有原发灶的颅内转移灶 ,CT诊断较明确 ,CT发现颅内转移灶而原发灶不明确者 ,首先应行胸部放射学检查 ,寻找原发灶。
Objective: To summarize the clinical data of 82 patients with intracranial metastases treated in our hospital and to perform CT diagnosis and analysis. Methods: All 82 patients were examined using the fourth generation of the US Picrer whole body CT machine, and the OM line was used as the baseline to continuously scan upwards. 11 layers, layer thickness 10mm, layer spacing 10mm, of which 63 cases were plain scan plus enhanced scan, 12 cases were plain scan only, 7 cases were direct enhanced scan, CT scan performance was as follows; Result: low density when plain scan 18 Cases, including 12 cases of lung cancer, 2 cases of liver cancer, 3 cases of breast cancer, 1 case of kidney cancer, was isodensity of 15 cases, including 14 cases of lung cancer, 1 case of esophageal cancer, was nodular slightly higher density Among 39 cases, 28 cases were lung cancer, 5 cases were esophageal cancer, 2 cases were prostate cancer, 1 case was thyroid cancer, 2 cases were choriocarcinoma, 3 cases were uneven density on plain scan, and there was obvious edema around the lesion. 79 cases, 3 cases without edema, only showed a slightly high density of nodules, including mild edema in 15 cases, moderate edema in 7 cases, severe edema in 53 cases, the majority of lesions occupy significant effect, 72 cases with lateral ventricle Or the three ventricles were deformed and deformed, and the median line structure of 70 cases was significantly shifted. The enhanced scanning tumors showed clear shapes and the lesions were presented. Twenty-two cases were reinforced, 23 cases with nodular or patchy enhancement, 18 cases with annular and nodular enhancement, and 7 cases with irregular shape enhancement. Conclusion: Intracranial metastases with primary lesions , CT diagnosis is more specific, CT found intracranial metastases and the primary lesion is not clear, the first chest radiograph should be performed to find the primary lesion.
