肺良性神经内分泌瘤的影像诊断与病理对照研究（附28例报告）

Benign Neuroendocrine Tumor of the Lung:Imaging Diagnosis and Pathologic Correlation(RepOrt of 28 Cases)

笔者报告一组肺良性神经内分泌瘤的影像表现与病理对照研究结果。Ｘ线表现为肺内圆形或类圆形结节或肿块，大小１．５～５ｃｍ，边缘光滑锐利，密度多较均匀，偶见钙化，可有浅分叶，邻近支气管可受压移位。本瘤Ｘ线表现具有一般肺内良性肿瘤的特征，因此不易鉴别。病理上见瘤灶与邻近肺组织之间界限清楚，多有完整或不完整的包膜或假包膜，可推移临近支气管或血管，可有钙化。

The authors reported an imaging-pathologic study of 28 cases of benign neuroen-docrine tumor of the lung. On chest radiograph,the tumor presented as solitary round or nearly round nodule or mass from 1.5 to 5cm in diameter with sharp and smooth margin sometimes with slight lobulation. Most tumors were relatively homogeneous in density but calcifications were seen occasionally. Pressure and displacement of neighboring bronchus might be seen, This kind of tumor demonstrated the general X-ray features of pulmonary benign tumor making differential diagnosis dif- ficult.Pathologically the tumor was well defined from surrounding lung tissue and there was a fir-brous capsule or pseudocapsule in most cases.
