目的:探讨肺淋巴瘤样肉芽肿(LYG)的CT影像表现。方法:回顾性分析8例肺部LYG病例的CT影像表现,男性3例,女性5例,平均年龄42岁,其中5例含增强扫描。结果:病理结果 2例为1级,4例为2级,2例为3级;6例多发,其中1例为多发结节,4例以多发结节或肿块为主,伴有不同程度斑片影,1例为斑片影为主伴多发小结节;2例表现为单发结节或肿块;3例下肺分布为主,3例上肺分布为主,2例上下肺都有分布,6例多发结节均沿着支气管血管束分布,其中5例有胸膜下病灶分布。8例病灶结节或肿块边缘粗糙,周围均有晕征;4例平扫可见病灶中央较外周密度稍低;3例可见到空气支气管征;1例病灶内见小空洞;5例行增强扫描病例均可见病灶边缘强化,中心平均强化值13.2 Hu。5例伴纵隔淋巴结肿大。结论:沿支气管血管束分布的多发结节或肿块,伴周围晕征以及边缘环形强化为肺部LYG的常见表现。
Objective: To investigate the CT findings of pulmonary lymphatic granuloma (LYG). Methods: CT images of 8 cases of LYG in lung were retrospectively analyzed. There were 3 males and 5 females, with a mean age of 42 years. Among them, 5 cases had enhanced CT scan. Results: The pathological results were grade 1 in 2 cases, grade 2 in 4 cases, grade 3 in 2 cases, grade 3 in 2 cases, multiple nodules in 6 cases, multiple nodules in 1 case, multiple nodules or lumps in 4 cases, 1 case of patchy nodules with multiple nodules, 2 cases of single nodules or lumps, 3 cases of lung distribution, 3 cases of upper lung distribution, 2 cases of upper and lower lungs Distribution, 6 cases of multiple nodules were distributed along the bronchovascular bundle, of which 5 cases were subpleural lesions. 8 cases of nodules or lumps had rough edges and had halo signs around them; 4 cases showed slightly lower central density than those in the center of the lesion; air bronchial signs were seen in 3 cases; small cavities were found in 1 case; enhanced scan was performed in 5 cases Cases can be seen enhanced lesion edge, the center of the average enhancement value of 13.2 Hu. 5 cases with mediastinal lymph nodes. CONCLUSIONS: Multiple nodules or masses along the bundle of bronchovascular bundles with peripheral halo sign and edge ring enhancement are common manifestations of LYG in the lung.
