肺内孤立球形病变的X线诊断

目的　提高X线检查对肺内孤立球形病变诊断重要性的认识。方法　 40 2例肺内孤立球形病变 ,其中手术及病理证实3 98例 ,4例肺脓肿经临床证实。全部病例均摄胸部正位片 ,3 68例有侧位胸片 ,95例有病灶体层。结果　常见病周围型肺癌 96例 ,肺结核瘤 3 3例 ,肺包虫病 2 5 3例 ,肺脓肿 9例 ,转移瘤 3例。炎性假瘤、错构瘤、肺肉瘤各 2例。肺母细胞瘤、肺纤维瘤各 1例。常见病大多有典型X线表现 ,结合临床诊断容易明确。少见病有时缺乏特征性表现 ,大多数诊断较为困难。结论　X线检查对肺内孤立球形病变的诊断有重要的价值 ,仍为首选的方法。

X-ray Diagnosis of Solitary Globular Lesion of Lung

Objective To promote the understanding of X-ray examination in the diagnosis of solitary globular lesion of lung.Methods Of 402 cases with solitary globular lung lesion, 398 were proved by operation,pathology and 4 cases of lung abscess were proved by clinical therapy. Anteroposterior radiogrphs were taken in all cases;lateral radiogrphs were taken in 368 cases.Results Of these cases ,there were peripheral lung cancer 96,tuberculoma 33,lung echinococcosis 253, lung abscess 9, pulmonary metastatic carcinoma 3.There were no characteristic signs in the rare diseases. Therefore , it's difficult to diagnose these lesions. The rare diseases include inflammatory pseudotumor 2, pulmonary hamartoma 2 , lung sarcoma 2 , pneumoblastoma 1 and lung fibroma 1. Conclusion X-ray examination is important in the diagnosis of solitary globular lung lesion.
