14例HIV并胸部马红球菌病的动态观察分析

Dynamic observation of 14 HIV patients complicated with chest rhodococcus equi disease

目的：探讨HIV并胸部马红球菌病影像动态变化特点。方法分析由细菌学或病理证实HIV并胸部马红球菌病14例，经2-4次X线摄影及2-3次计算机体层摄影影像图片进行动态观察。结果随访观察时间1~12个月，平均4.3个月。肺实变病灶12例，病灶范围消散50%以上6例，消散50%以下4例，无变化1例，肺实变范围增大1例。空洞12例，完全闭合1例，空洞缩小10例，空洞融合成大空洞1例。结节病灶14例，结节病灶数量消散50%以上5例，消散小于50%，大于1%7例，结节数量无变化1例，结节数量增多1例。结论 HIV并胸部马红球菌病影像表现多为实变、空洞、结节灶；结合临床病史、不同时期影像表现的特点，大部分HIV并胸部马红球菌病可以明确诊断。

Objective To study the dynamic characteristics of HIV patients complicated with chest rhodo-coccus equi disease. Methods The clinical data of 14 HIV patients complicated with chest rhodococcus equi disease were retrospective analyzed. They were given 2 to 4 times of X-ray radiography and 2 -3 times of computed tomo-graphy. Results They were followed-up 1-12 months, with an average of 4. 3 months. There were 12 cases of con-solidation of lung lesions, including 6 cases of the scope of consolidation of lung lesions dissipated more than 50%, 4 cases of dissipate below 50%, 1 case without change and 1 case of pulmonary consolidation scope enlargement. There were 12 cases of cavitates, including 1 completely closed case, 10 cases of narrow hole and 1 case of big cabitate.There were 14 cases of nodules. Conclusion The images of HIV patients complicated with chest rhodococcus equi disease show consolidation, hollow, and nodules.
