继发性肺结核空洞86例的CT表现

摘要

Objective To analyze of CT manifestation of secondary pulmonary tuberculosis cavity type, deepen understanding of damaged lung CT images and help clinical observation. Methods Collected by anti-tuberculosis treatment in hospital and CT examination of 86 cases were retrospectively analyzed, according to the course of the disease and CT as classified. Results Secondary pulmonary tuberculosis cavity CT manifestations can be divided in-to infiltrating type empty and 28 cases of TB, fiber type hollow 58 cases were tuberculosis. 28 cases infiltrating type hollow, single-shot in 5 cases, multiple 20 cases, diffuse small hole (3 cases), empty and maximum diameter was about 0.3~5 cm. Fiber type hollow 58 cases were tuberculosis, single 32 cases, multiple 26 cases, empty and maximum di-ameter is about 1.5~15 cm, on one side of the lung damage to lung in 16 cases, bronchial stenosis, expansion, the distortion of 45 cases, hollow inside see mold ball (3 cases). Conclusion Patients with secondary pulmonary tuber-culosis cavity in a mountainous area are mainly middle-aged and old cases is given priority to, the most common chronic fibrosis tuberculosis cavity, CT performance mixed to form more pathological changes, the late often cause lung segment and lung damage.%目的：分析继发性肺结核空洞的CT表现类型，加深对毁损肺的CT影像认识，有助于临床治疗观察。方法收集经住院抗结核治疗并进行CT检查的86例病例进行回顾性分析，根据病程及CT征像进行分类。结果继发性肺结核空洞CT表现可分为浸润型结核空洞28例，纤维型结核空洞58例；28例浸润型空洞中，单发5例，多发20例，弥漫性小空洞3例，空洞最大径约0．3～5 cm；纤维型结核空洞58例，单发32例，多发26例，空洞最大径约1．5～15 cm，一侧肺毁损肺16例，支气管狭窄、扩张、扭曲45例，空洞内见霉菌球3例。结论肺继发性肺结核空洞在山区患者主要以中老年病例为主，慢性纤维化结核空洞最多见，CT表现以多形态病变混杂，晚期常致肺段、肺叶毁损。
