目的 :探讨肺内孤立性球形病灶的诊断与鉴别诊断及其临床意义。方法 :回顾分析经临床手术及病理证实的周围性肺癌 2 1例、肺结核球 8例、肺炎性假瘤 5例及肺内错构瘤 5例 ,并对其影像改变加以总结。结果 :周围性肺癌的影像学改变以“分叶征”、“毛刺征”、“小泡征”及“血管连接征”、“胸膜凹陷征”为主要表现 ;肺结核球的影像改变以“卫星病灶”为主要表现 ;肺炎性假瘤的影像改变以“桃尖征”为主要表现 ;肺内错构瘤以“爆米花”样钙化为主要表现。结论 :X线与 CT扫描是检查肺内孤立性球形病灶的主要手段之一 ,其诊断与鉴别诊断对临床的进一步治疗具有重要的价值和意义
Objective: To investigate the diagnosis and differential diagnosis of solitary spherical lesions in the lung and its clinical significance. Methods: 21 cases of peripheral lung cancer, 8 cases of pulmonary tuberculosis, 5 cases of pulmonary inflammatory pseudotumor and 5 cases of pulmonary hamartoma confirmed by clinical operation and pathology were retrospectively analyzed. The imaging changes were summarized. Results: The imaging changes of peripheral lung cancer were mainly manifested as “lobulation sign”, “burr sign”, “vesicle sign” and “vascular connection sign” and “pleural indentation sign”. The image of tuberculosis ball changed with “satellite Lesions ”as the main performance; Pneumonia pseudotumor image changes to“ peach tip syndrome ”as the main performance; pulmonary hamartoma with“ popcorn ”-like calcification as the main performance. Conclusion: X-ray and CT scan is one of the main methods to detect solitary spherical lesions in the lung. The diagnosis and differential diagnosis of X-ray and CT are of great value and significance for clinical further treatment
