【摘要】：目的總結(jié)肺黏膜相關(guān)淋巴組織淋巴瘤的CT及PET-CT表現(xiàn),提高對(duì)該病的認(rèn)識(shí)。方法回顧性分析21例經(jīng)病理證實(shí)的肺黏膜相關(guān)淋巴組織淋巴瘤的CT及PET-CT的影像表現(xiàn)。結(jié)果所有患者均行CT掃描,其中20例行增強(qiáng)掃描,1例平掃。病灶密度均勻,除1例可見鈣化外,其余病變均未見鈣化,未見明顯低密度區(qū),平掃平均CT值為(47±11)HU,增強(qiáng)后平均CT值為(77±13)HU。發(fā)病部位以跨葉分布為主,19例有右中葉或左舌葉病變;CT征象:多發(fā)實(shí)變15例,多發(fā)結(jié)節(jié)3例,單發(fā)腫塊2例,單發(fā)結(jié)節(jié)1例(合并結(jié)節(jié)病,多發(fā)小粟粒病灶)。其中病灶內(nèi)支氣管氣相征16例,增強(qiáng)后病灶中出現(xiàn)血管造影征16例,病灶緊貼縱隔呈三角型灌注征13例。合并支氣管擴(kuò)張6例,有3例結(jié)節(jié)合并暈征,小葉間隔增厚9例,肺門及縱隔淋巴結(jié)增大9例,CT均顯示為直徑1.5 cm小淋巴結(jié);胸腔積液7例,2例胸膜增厚,1例侵犯胸壁。6例行PET-CT檢查,均顯示病灶明顯放射性濃聚,SUV值均2.5,為3.5~11.7,平均6.7±3.6;4例顯示肺門及縱隔淋巴結(jié)有放射性濃聚,SUV值為2.7~3.4,平均3.0±0.3。結(jié)論肺黏膜相關(guān)淋巴組織淋巴瘤部分病灶在CT上有較具特征性的表現(xiàn),對(duì)于診斷有一定提示作用;PETCT對(duì)于病灶活性的判斷有一定優(yōu)越性,最終確診需要病理組織學(xué)和免疫組織化學(xué)。
[Abstract]:Objective to summarize CT and PET-CT findings of pulmonary mucosa-associated lymphoid tissue lymphoma. Methods CT and PET-CT findings of 21 cases of pathologically proved lung mucosa-associated lymphoid tissue lymphoma were retrospectively analyzed. Results CT scan was performed in all patients, of which 20 cases underwent enhanced scan and 1 case underwent plain scan. There was no calcification in all the lesions except one case with calcification. The mean CT value was 47 鹵11 HUU on plain scan and 77 鹵13 Hu on enhancement. There were 19 cases with right middle lobe or left tongue lobe lesions, including 15 cases of multiple consolidation, 3 cases of multiple nodules, 2 cases of single masses and 1 case of single nodules (complicated with sarcoidosis, multiple miliary lesions). Among them, 16 cases had bronchial vapor sign, 16 cases had angiographic sign after enhancement, 13 cases had triangle perfusion sign close to mediastinum. There were 6 cases of bronchiectasis, 3 cases of nodules with halo sign, 9 cases of interlobular septal thickening and 9 cases of hilar and mediastinal lymph node enlargement. In 7 cases of pleural effusion and 2 cases of pleural thickening and 1 case of pleural wall invasion, PET-CT examination was performed in 1 case. All of them showed that the value of SUV was 2.5 (3.5 鹵3.6), and the mean value was 6.7 鹵3.6 (4 cases). The mean value of SUV was 2.7 鹵3.4 (mean 3.0 鹵0.3) in hilar and mediastinal lymph nodes. Conclusion some lesions of lung mucosa-associated lymphoid tissue lymphoma have characteristic features on CT, which may be helpful for diagnosis. PETCT has some advantages in judging the activity of the lesions. The final diagnosis requires histopathology and immunohistochemistry.
