肺部薄壁空洞性病变的CT诊断

<TITLE>CT DIAGNOSIS OF PULMONARY THIN-WALL CAVITIES

目的探讨肺部薄壁空洞性病变的诊断与鉴别诊断。方法收集病理与临床证实的薄壁空洞性病变共31例,全部病例均有CT片,其中14例CT增强扫描。男17例,女14例,平均年龄65.5±7.3岁。临床无症状5例,不同程度症状26例。分析病例的CT表现和临床表现。结果31例薄壁空洞型病变中肺癌空洞8例,肺结核14例,肺转移瘤5例,肺曲霉病1例,急性金葡菌肺炎3例,其中11例为多发空洞病变,其余为单发病变。CT表现各病种之间各不相同,临床表现为咳嗽、咯血、发热、胸闷、胸痛等。各病种间无差异。结论不同薄壁空洞的临床表现无差异性。其CT表现有一定差异,CT是诊断和鉴别诊断的主要方法。

Objective To increase the recognition of diagnosis anti differential diagnosis of pulmonary thin-wall cavities. Methods 31 cases of lung cavity proved by pathology were reported. All cases had their own CT plain films while 14 cases had enhancement exam. 17 were male, 14 were female, The average age was 65.5 ± 7.3 years old. 5 of 31 had no clinical findiugs while 26 had different clinical features. The CT and clinical fiudings were studied in detail. Results 8 of 31 cases were lung cancer, 14 were tuberculosis, Metastases caused lung cavity were found in 5 cases, 1 was pulmonary mycosis anti 3 were staphyloccal pneumonia, 11 of 31 cases were muhi-cavity diseases while the rest were solitary cavity. Different pathological cavities had its different CT features. Clinical symptoms were cough or expectoration, hemoptysis . fever, chest pain and fatigue. No difference among different cavity diseases. Conclusions No difference has been found in clinical features among these cavities.There are different CT findings hetwcen different pathological cavities. CT is the main method to explore the cavity character and to make the diagnosis.
