目的探讨肾上腺淋巴瘤的CT特征表现,以提高对本病的进一步认识。方法回顾性分析12例经手术和穿刺活检病理证实的肾上腺淋巴瘤,分析其影像学特点。结果在这12例病例中,单侧2例,双侧10例,共22个肿块,12例均行CT平扫及增强扫描,平扫表现为肾上腺区大小不等软组织肿块,密度均匀或不均匀,边界清晰或不清晰,增强扫描动脉期轻中度强化,强化均匀或欠均匀,部分病例延迟强化。12例中2例侵犯同侧肾脏及血管,2例肝脏受侵,1例侵犯腔静脉致瘤栓形成。结论肾上腺淋巴瘤具有一定的自身影像学特征。
Objective To investigate the CT features of adrenal lymphoma to improve the understanding of this disease. Methods Retrospective analysis of 12 cases of adrenal lymphoma confirmed by surgery and biopsy biopsy, and analyzed its imaging features. Results In these 12 cases, there were 2 cases of unilateral and 10 cases of bilateral total. Twenty-two tumors were found in all, 12 cases underwent CT scan and contrast-enhanced scan. Uniform, clear or unclear boundary, enhanced scan arterial light mild enhancement, enhanced uniform or less uniform, delayed enhancement in some cases. In 12 cases, 2 cases infiltrated the ipsilateral kidney and blood vessels, 2 cases suffered liver invasion, and 1 case invaded the vena cava to form tumor thrombus. Conclusion Adrenal lymphoma has its own imaging features.
