【摘要】：目的探討巨淋巴結增生癥(giant lymph node hyperplasia,GLNH)的多層螺旋CT(MSCT)表現,旨在提高對本病的認識。資料與方法回顧性分析經病理證實的7例GLNH患者的MSCT表現,其中平掃+增強5例,2例僅行平掃。結果 7例中,1例彌漫型病變表現為肺內間質性炎癥和肺門、縱隔淋巴結腫大;6例局灶型病變中,腹膜后和肺門各1例,縱隔和頸動脈鞘區(qū)各2例,平掃均表現為邊界清晰的孤立軟組織密度影,其中腹膜后1例密度不均勻,增強掃描呈"網格"樣強化,余病灶密度均勻,增強掃描呈動脈期中度均勻強化,門靜脈期、延遲期持續(xù)強化。2例縱隔病變內可見"分支"狀、"斑點"狀鈣化;3例周邊可見大血管分支,4例周圍可見大小不等的淋巴結。結論局灶型GLNH的MSCT表現有一定的特征性,多可以確診;彌漫型GLNH的MSCT表現無顯著特征,需要結合臨床資料綜合考慮。
[Abstract]:Objective to investigate the MSCT findings of giant lymph node hyperplasia GLNH in order to improve the understanding of the disease. Materials and methods the MSCT findings of 7 patients with GLNH confirmed by pathology were retrospectively analyzed. Results of the 7 cases, 1 case presented with interstitial inflammation and hilum, 6 cases with mediastinal lymphadenopathy, 1 case with retroperitoneal and 1 case with hilar pneumonitis, 2 cases with mediastinum and 2 cases with carotid artery sheath area, and 1 case with retroperitoneal and hilar pneumonitis, 2 cases with mediastinal lymphadenopathy and 6 cases with focal lesions of mediastinal lymph nodes. Plain scan showed solitary soft tissue density with clear boundary, in which the density of retroperitoneal was not even, the enhancement was "grid" like enhancement, the density of the remaining lesions was even, the enhancement showed moderate homogeneous enhancement in arterial phase and portal vein phase. "branching" was seen in 2 cases of mediastinal lesions during delayed phase continuous enhancement, and "branching" was seen in 3 cases. In 4 cases, lymph nodes of varying sizes were found around the large vessels. Conclusion the MSCT features of focal GLNH are characteristic and can be diagnosed, but the MSCT of diffuse GLNH has no significant features and needs to be considered in combination with clinical data.
