目的探讨军营内腺病毒肺炎的 常见CT表现，并分析其病理基础。方法 收集2016年10-11月陕西省某新兵训练营 被确诊腺病毒感染而入住我院，且胸部CT 检查发现明显肺部病变的14例患者进行影 像学分析。结果 14例病例中，12例为肺 部单发病变，2例为肺内两处病变，共计 16处病灶。分布：病变多见于双肺中下 叶，其中右肺上叶3处，中叶4处，下叶5 处；左肺上叶1处，下叶3处。形态：11处 病变呈类圆形，其余5处病变呈楔形；密 度：11处(68.8%)病变表现为斑片状密度 增高影；3处(18.7%)病变表现为大片类圆 形实变并周围磨玻璃影，边界不清，病变 内部可见空气支气管征；2处(12.5%)病变 表现为边界不清的小片状磨玻璃影。实变 性病变的吸收时间显著长于斑片状病变及 磨玻璃病变。结论 胸部CT检查对腺病毒 肺炎具有一定的诊断价值，病变多见于双 肺中下叶，早期CT表现以斑片状渗出性病 变为主，类圆形实变性病变伴周围磨玻璃 影较具特征性。

Objective To investigate the CT characteristics and pathological basis of adenovirus pneumonia in military. Methods We retrospectively reviewed the CT scanning of 14 patients with adenovirus pneumonia, who were recruited from a training camp and admitted to our hospital, between October and November, 2016. Results Twelve patients had single lesion and the rest 2 had two lesions, respectively. Distribution: lesions were more frequently observed in the middle and lower lobes. There were 3 lesions in the upper lobe, 4 lesions in the middle lobe, and 5 lesions in the lower lobe of the right lung. Meanwhile, there were 3 lesions in the lower lobe and 1 lesion in the upper lobe of the left lung. Morphology: the lesions were round-like in 11 and wedge-shaped in 5 patients. CT attenuation: it was patchy opacity in 11 patients (68.8%), round-like and air-space consolidation with ill-defined ground-glass opacity in 3 patients (18.7%), and small patches of ground-glass opacity in 2 patients. The absorption time of consolidation is significantly longer than the patchy opacity and ground-glass opacity. Conclusion Thoracic CT scanning play an important role in the diagnosis of adult adenovirus pneumonia. The lesions were commonly located in the middle and lower lobes of bilateral lungs. Patchy opacity was more frequently observed in the early stage. The most characteristic manifestation of CT scanning is round and air-space consolidation with ground-glass opacity.
