摘 要：目的 探讨正常人胸透(片)上膈顶尖角状突起影的解剖学基础。 材料与方法 胸透正常人2043例，对膈顶有尖角状影者其中13例行胸部正侧位摄片和HRCT扫描对照。复习117例正常胸部常规CT扫描肺窗片。用间距5mm的HRCT扫描20例正常人下胸部。 结果 胸透(片)膈顶尖角状影检出率：男3.5%，女7.0%。 结论 胸透(片)膈顶尖角状突起影CT上显示为肺韧带或膈神经。

ABSTRACT ： Objective To study the anatomical basis ofsharp-horn like opacity at diaphragmatic fornices on chest fluoroscope or chest film innormal subjects. Materialsand Methods (1)Chest fluoroscopy was performed in 2 043 normal subjects, and PA and lateral chest films aswell as HRCT were made in 13 cases showing sharp-horn like opacity ar diaphragmatic fornices. (2) The conventional chest CT scans of 117 normal cases were reviewed with lungwindow. (3) HRCT scanning using 5mm intervals of lower thorax was conducted in 20 normalsubjects. Results The sharp-horn like opacity atdiaphragmatic fornices on chest fluoroscope or chest film was demonstrated in 3.5% and7.0% of normal male and female, respectively. Conclusion Observation with CT scanning indicates that the sharp-hornlike opacity at diaphragmatic fornices on chest fluoroscope or chest film in normalsubjects is the projection of pulmonary ligament or phrenic nerve.
