原发性肺鳞癌的CT表现

The CT Features of Primary Pulmonary Squamous Carcinoma

目的 分析肺鳞癌的CT表现 ,探讨其影像特征 ,提高估计肺癌组织类型的可能性。方法 收集 46例经纤维支气管镜、手术病理证实的中、低分化鳞癌 ,对其CT表现进行全面地回顾总结。结果 ①右肺发病率高于左肺 ,中央型多于周围型。②病变致密 ,肿块形态连续、完整、界面清晰。③边缘以分叶、短毛刺为主。支气管腔内肿物、空洞、钙化较其他类型肺癌常见 ,肺不张多见。④灶状坏死是强化后特征表现。结论 认识鳞癌的特征表现有助于定性诊断率的提高 ,为临床选择正确的治疗手段创造条件。

Purpose To analyze the CT features of pulmonary squamous carcinoma, discuss its imaging characteristics to improve the ability of estimating the histological types of pulmonary carcinoma.Methods Forty six cases of moderately and poorly differentiated primary pulmonary squamous carcinoma were collected, which were all proved by bronchfiberscopy and operation, their CT manifestations were studied comprehensively.Results ①morbidity in right pulmonary was higher than in left, and central types were more than peripheral ones. ②tumor was soliddensity and with continuous, complete shape and distinct interface. ③Lobulation and short spiculation were often found in margin. Mass inside bronchi, cavitation or calcification was more common than other type of pulmonary carcinoma.Atelectasis was found frequently. ④The focal necrosises were special manifestation after enhanced.Conclusion The imaging features are helpful to define diagnosis and choose rational therapy in clinic.
