摘　　要：回顾性分析了１６３例原发性周围型肺腺癌的Ｘ线表现与误诊原因，其典型表现为肺内孤立性肿块或结节（１３９例，８５．２７％），直径小于４ｃｍ，边缘有小分叶和短细毛刺。弥漫小结节型和肺炎浸润样型虽所占比例不多，但误诊率较高。X-ray signs and cause of misdiagnosis of 163 cases with primary petipheral adenocarcino-ma were retrospectively analysed.The solitary pulmonary mass or nodular type was found in 139 cases(85.3%),the diffuse small nodular type in 12 cases(7.98%)and the pneumonic infilttation type in 11 cases(6.75%).The typical roentgen pattern of peripberal pulmonary adenocarcinoma was a shadow of solitary pul-monary mass of nodule with small lobate margins and with spicules from its periphery.Its diameter was oftensmaller than 4 cm.The tail sign and vacuole sign were more often seen than those of other histotypical lungcancer.
