摘要
目的:探讨CT在肺中央型类癌诊断和鉴别诊断中的价值。方法:收集18例肺中央型类癌,对其CT表现进行回顾性分析,CT表现包括病变部位、形态、增强后改变、间接征象(阻塞性改变、淋巴结转移、转移征象)。结果:病变完全位于管腔内8例(44.4%),位于管腔外1例(5.6%),同时累及管腔内外者9例(50.0%)。病灶大小:小于2cm者3例(16.7%),2cm^5cm者11例(61.1%),大于5cm者4例(22.2%)。明显强化者10例(55.6%),其中,均匀强化者6例,不均匀强化者4例;没有明显强化者8例(44.4%)。同侧纵隔淋巴结肿大1例,对侧淋巴结也肿大者1例,没有淋巴结肿大者16例。远处器官转移者1例(肝脏)。结论:综合分析CT表现有助于肺中央型类癌的诊断和鉴别诊断。
Objective： To evaluate the value of CT in the diagnosis and differentiation of central bronchial earcinoid. Methods： Eighteen cases of central bronchial carcinoid were collected, and the CT findings, including location and morphology of the lesion, contrast en- hancement, indirect CT manifestations （obstructive changes, lymph node metastasis, and distant metastasis）, were analyzed. Results. Eight cases （44.4%） were intracavitary, one case （5.6%） was extracavitary, 9 cases （50.0%） were both intracavitary and extracavi- tary. The size of the lesion： three cases （16.7%） were smaller than 2 cm, eleven cases （61.1%） ranged from 2 ~ 5 cm, four cases （22.2%） were larger than 5 cm. Ten cases （55.6%） had significant enhancement, of which 6 cases had homogeneous enhancement, and 4 cases had heterogeneous enhancement. Eight cases had no enhancement. There was one case of ipsilateral mediastinal lym- phadeneetasis and one case of contralateral mxliastinal lymphadeneetasis. 16 cases had no lymphadenectasis. There was one case of liver metastasis. Condusion： Comprehensively analysis of CT findings is very helpful for the diagnosis and differentiation of central bronchial carcinoid.
