摘要

摘要: 目的：探讨肺类癌的CT表现，提高对该病的影像诊断水平。方法：回顾性分析并总结8例病理确诊为肺类癌患者的CT征象。结果：8例肺类癌均为单发病灶。4例中央型肺类癌中，4例表现为支气管腔内结节灶、结节长轴与支气管长轴平行呈“平行征”改变，4例密度均匀，2例见分叶征，4例伴阻塞性炎症，3例伴阻塞性不张，2例伴阻塞以远黏液栓，2例伴少量胸腔积液。4例周围型肺类癌中，2例密度不均匀，2例见浅分叶征，1例见短毛刺征，3例见胸膜增厚，1例见斑点状钙化，未见阻塞性肺气肿、阻塞性炎症、阻塞性不张及胸腔积液等征象。所有病例均未见肺门及纵隔淋巴结肿大，未见远处转移。进行增强扫描的5例病灶均表现为中度-明显程度强化。结论：肺类癌的CT表现具有一定特征，掌握其特征性改变可提高诊断准确率，但确诊仍需依靠病理。

Abstract: Objective: Explore the CT findings of pulmonary carcinoid to improve the diagnosis of the disease. Methods: Clinical data and radiologic findings were retrospectively reviewed for 8 patients with pathologically confirmed pulmonary carcinoid. Results: All the 8 cases were unilateral, and 4 of them were central pulmonary carcinoid. The CT features of the 4 central pulmonary carcinoid were the hypodense nodule in the main bronchus showed the "parallel thickening" sign, with obstructive inflammation and pulmonary atelectasis. None of the lesions showed the calcification, necrosis or cystic change. Besides, the other 4 cases were peripheral pulmonary carcinoid. Two cases with shallow lobulations were observed. Two cases showed the "Short burr", one cases with calcification, and 2 cases with heterogeneous hypodense nodules. There are 3 cases with pleural thickening. Of the 4 cases of peripheral pulmonary carcinoid, there were no obstructive inflammation, mucoid impactions sign, obstructive atelectasis,obstructive emphysema or pleural effusion. All cases had no hilus pulmonis or mediastinal lymph node metastasis or distant metastasis. Five of the 8 cases underwent enhancement scan, and all of them showed homogeneously significant enhancement. Conclusions: pulmonary carcinoid showed the certain spectrum of CT features which may improve the diagnosis.
