【摘要】：目的原发性肺浸润型黏液腺癌极少见,相关文献报道较少,本文探讨其多层螺旋CT(MSCT)表现,提高对本病的认识。资料与方法回顾性分析41例经手术或穿刺病理证实为原发性肺浸润型黏液腺癌患者的临床资料,所有患者行MSCT平扫,其中27例行CT增强扫描。分析病灶数量、分布、形态、密度,测量病灶主体密度和强化幅度,比较不同类型的病灶扫描前后CT值和增强幅度的差异。结果 41例患者病灶数量:单发40例,多发1例。单发病灶分布:右肺上叶5例、中叶1例、下叶17例,左肺上叶5例、下叶12例;多发病灶1例(左肺下叶、右肺上叶、中叶、下叶)。形态:圆形(类圆形)29例,不规则形12例。密度:磨玻璃密度4例,单纯实变密度11例,混合实变密度26例。圆形(类圆形)病灶的扫描前后CT值、增强幅度均高于不规则形病灶,差异有统计学意义(t=5.00、6.51、14.06,P0.05)。结论原发性肺浸润型黏液腺癌MSCT征象以单发圆形(类圆形)病灶、双肺下叶、混合实变密度多见,实性病灶平扫密度低于肌肉,增强扫描呈轻度至中度异常强化,圆形(类圆形)病灶比不规则形病灶密度高,强化幅度大。
[Abstract]:Objective Primary invasive mucinous adenocarcinoma of the lung is rare, and there are few related literatures. The MSCT findings of multilayer spiral CTT are discussed in order to improve the understanding of the disease. Materials and methods Clinical data of 41 patients with primary pulmonary infiltrating mucinous adenocarcinoma proved by operation or puncture pathology were retrospectively analyzed. All patients underwent plain MSCT scan, 27 of them underwent CT enhanced scan. The number, distribution, morphology and density of the lesions were analyzed. The main body density and enhancement amplitude were measured, and the difference of CT value and enhancement amplitude between different types of lesions before and after scanning were compared. Results the number of lesions in 41 patients was single in 40 cases and multiple in 1 case. There were 5 cases in the upper lobe of the right lung, 1 case in the middle lobe, 17 cases in the lower lobe, 5 cases in the upper lobe of the left lung and 12 cases in the lower lobe, and 1 case had multiple lesions (left lower lobe, right superior lobe, middle lobe, inferior lobe). Shape: round (like round) in 29 cases, irregular in 12 cases. Density: grinding glass density in 4 cases, pure solid density in 11 cases, mixed solid density in 26 cases. The CT value and enhancement amplitude of round (round) lesions were higher than those of irregular lesions before and after scanning, and the difference was statistically significant (P 0.05). Conclusion the MSCT signs of primary pulmonary infiltrating mucinous adenocarcinoma are single round (round) lesions, mixed density of the inferior lobes of both lungs, the density of solid lesions is lower than that of muscle, and the enhancement scan is mild to moderate abnormal enhancement. The density and enhancement range of round (round) lesions were higher than that of irregular ones.
