肺炎性假瘤31例的X线表现分析

Roentgenologic Manifestation of Pseudo-inflammatory Tumor of Lung.An Analysis of 31 Cases

本文报道我院自1974年4月至1982年4月,8年间共收治肺炎性假瘤31例,其中男18例,女13例,均经手术和病理证实。X线检查发现右肺22例(以肺下叶为主,计13例),左肺9例(下叶5例)。肿块阴影多位于肺边缘区,呈圆形或椭圆形,且边界清晰(16例),或毛刺状(11例,其中7侧尚呈分叶状),另4例为浸润性。密度居中而均匀(12侧),少数较密(4例)或稍淡(7例),易误诊为良性瘤或癌。个别者见厚壁空洞(2例),肿块内见斑点状钙化(2例)或浸润状(4例),易误诊为癌,结核球或错构瘤。呈浸润状者,术中皆证实与周围组织粘连,本纽共17例,均有平片断层,26例肺门正常,5例肺可见肿大淋巴结,但病理检查皆为炎性。

During April 1974 to April 1982, 31 cases of pseudo-inflammatory tumor of the lung were treated operatively and proven histologically in Tianjin Cancer Hospital. Eighteen were male and 13 femle. X-ray examination revealed that the lesions were located in the right lung in 22 cases (13 in the lower lobe) and the left lung in 9 cases (5 in the lower lobe). Most of the lesions were in the peripheral region, round or oval in shape, with clear cut border (16 cases), however, some (15 cases) showed vague border. The density of the shadow was medium in 12 cases, heavy in 4 cases and mild in 7 cases. Thick walled cavity (2 cases), spotted calcifications (2 cases) or infiltrative mass (4 cases) were occasionally seen. Seventeen cases with somewhat vague border were identified by adhesions to the surrounding tissue (largely the peripheral pleura or diaphragm). On tomograms of the hilum, in only 5 cases enlargement of the hilar lymph nodes was noted, and later proved to be inflammatory changes histologically. These lesions were readily misdiagnosed as benign or malignant tumors.
