摘要
目的 探讨肺囊肿CT表现形式及其病理基础。资料与方法 回顾性分析行CT扫描且有手术及病理证实的肺囊肿病例 4 9例共 1 5 5个病灶 ,CT观察病变部位、数目、形态、大小、密度、囊壁厚度及周围肺野改变。病理改变以手术所见及病理报告为准。结果 CT扫描表现为薄壁含气囊腔 1 0 6个 ,周围肺野无条索影及渗出实变 ,病理报告为单纯肺囊肿。CT扫描表现为厚壁含液和 /或含气囊腔 4 1个 ,周围肺野可见条索影和 /或渗出实变 ,病理改变为肺囊肿合并感染 1 3个 ,肺囊肿合并灶性纤维组织增生 2 8个。CT扫描表现为软组织密度肿块 8个 ,其中肺囊肿合并出血 1个 ,肺囊肿合并纤维组织增生及肉芽肿形成 3个 ,肺囊肿合并纤维组织增生及炎性假瘤形成 4个。结论 肺囊肿CT表现形式有 3种类型 ,即薄壁囊腔型、厚壁囊腔型。
Objective To investigate CT manifestations of bronchogenic cysts and their pathologic correlation.Materials and Methods CT findings in 49 patients with pathologically proved bronchogenic cysts (total 155 cysts) were retrospectively analyzed, focusing on the observation of the lesion's site, number, shape, size, density, cystic wall thickness and the neighboring lung field.Results On CT scans, 106 cysts presented as thin walled, air containing space, the surrounding lung field was clear of consolidation and fibrosis. Pathologically, all the 106 cysts were simple, uncomplicated cysts. Forty one cysts were thick walled, containing fluid and/or air, with consolidation and/or stripe shadows in neighboring lung field. Pathologically, infection was complicated in 13 cysts and focal proliferation of fibrous tissue was seen in 28 cysts. The remaining 8 cysts displayed as masses of soft tissue attenuation, of which hemorrhage was complicated in one, fibrous proliferation and inflammatory granuloma in 3, and fibrous proliferation and complicated inflammatory pseudotumor in 4.Conclusion On CT scans, bronchogenic cysts have three patterns: (1) thin walled, air containing space; (2) thick walled, air containing space; and (3) mass like pattern.
