目的探讨肺腺癌蜂房征的CT表现。方法搜集经穿刺或手术病理组织学证实为肺腺癌且具有符合蜂房征定义CT表现的33例患者的临床资料,观察肺癌主体病灶及蜂房征的部位、形态、大小,蜂房征所占比例,边缘有无分叶、毛刺,近端有无血管纠集,远端有无阻塞性肺炎及肺不张等,以及有无淋巴结或远处转移。结果单发32例,多发1例。具有蜂房征表现的肺腺癌病灶共44个,其中呈结节或肿块型30例41个病灶,包括纯磨玻璃结节2个,部分实性结节12个,实性结节或肿块27个;呈炎症型病灶3个。病灶分布:右上肺10例,右下肺9例,右中肺3例,左上肺2例,左下肺8例,双肺多发1例。结节型或肿块型病灶大小:最大5.4 cm,最小0.9 cm,平均2.7 cm。除此以外,其他恶性征象有分叶出现率77.3%(34/44),毛刺出现率36.4%(16/44),血管集束征出现率25.0%(11/44),远端阻塞性炎症或肺不张出现率22.7%(10/44),胸膜凹陷出现率34.0%(15/44);1例同时合并空泡征。病理结果:高-中分化9例,非高中分化24例,其中3例部分存在贴壁生长。结论蜂房征更多见于肿块或结节型肺腺癌,结合肺腺癌其他CT表现,可进一步提高肺腺癌诊断的正确性。
Objective To investigate the CT findings of hives in lung adenocarcinoma. Methods The clinical data of 33 patients who were diagnosed as lung adenocarcinoma by puncture or pathological histology and had CT manifestations consistent with the definition of bee syndrome were collected. The location, shape, size, Whether there is edge of the leaves, burr, proximal vascular entrapment, distal obstructive pneumonia and atelectasis, and whether there is lymph node or distant metastasis. Results single hair 32 cases, multiple cases in 1 case. There were 44 lesions of lung adenocarcinoma with apiary manifestations, including 41 lesions of 30 cases of nodules or masses, including 2 purely ground glass nodules, 12 partially solid nodules, and solid nodules or lumps. A; inflammatory lesions were 3. Distribution of lesions: 10 cases of right upper lung, 9 cases of right lower lung, 3 cases of right middle lung, 2 cases of left upper lung, 8 cases of left lower lung and 1 case of double lung. Nodular or mass lesions size: maximum 5.4 cm, minimum 0.9 cm, an average of 2.7 cm. In addition, there were 77.3% (34/44) folds, 36.4% (16/44) burr appearances, 25.0% (11/44) appearances of vascular bundles, distal obstructive inflammation or The incidence of atelectasis was 22.7% (10/44), and the incidence of pleural indentation was 34.0% (15/44). One case had concurrent vacuolar symptoms. Pathological findings: high-moderate differentiation in 9 cases, non-high school differentiation in 24 cases, of which 3 cases of adherent growth. Conclusions Hives sign more common in lumps or nodular lung adenocarcinoma, combined with other CT manifestations of lung adenocarcinoma can further improve the diagnostic accuracy of lung adenocarcinoma.
