摘要
目的探讨原发性肾上腺淋巴瘤的CT检查特征及与病理学特点的关系。方法回顾性分析2000年6月至2011年3月经手术病理证实的6例原发性肾上腺淋巴瘤患者的临床资料。男4例，女2例。年龄18～62岁，平均51岁。单侧单发5例，双侧单发1例，共7个病灶。临床主要表现为上腹痛、不适等症状。6例均行CT平扫及多期增强扫描。6例均行手术治疗。分析6例CT检查特征与病理学特点的关系。结果7个病灶CT平扫表现为肾上腺区等密度或稍低密度软组织肿块，最大径3～11em，呈不规则形或椭圆形，境界清晰，密度均匀或轻度不均匀，CT值30～40HU，可包绕邻近血管及同侧肾脏；增强扫描动脉期强化不明显，CT值39～50HU；静脉期轻到中度强化，CT值47～66HU；延迟期持续强化，CT值60～78HU。病理检查光镜下见肿瘤细胞弥漫密集，大小较一致，核大，染色质呈颗粒状，肿瘤组织中间质成分相对较少，6个病灶中未见明显的出血、坏死及钙化，1个病灶中可见局部点、片状或单个瘤细胞坏死。结论原发性肾上腺淋巴瘤的CT检查特征与病理学特点有一定相关性；正确认识其病理学特点，有助于提高对其CT特征性表现的理解和认识。
Objective To evaluate the CT features of primary adrenal lymphoma and its relationship with pathology. Methods Pathologically proven primary adrenal lymphoma 6 eases were reviewed. There were 4 males and 2 females. The age was 18 -62 years, average age was 51 years. 5 cases was single tomur in unilateral, 1 case was bilateral disease. The main clinical manifestations were abdominal pain, abdominal discomfort. All patients had CT scan and were treated surgically. Results CT scan showed the characters of adrenal little low-density soft tissue mass ： the maximum diameter of 3 - 11 cm, irregularly shaped or oval-shaped, multi-state a clear, homogeneous or slightly inhomogeneous density, CT value was 30 -40 HU. Lesions could be embedded or close to blood vessels and the ipsilateral kidney. The lesions were not enhanced arterial phase enhancement, CT value was 39 -50 HU. The lesions showed vein phase of mild to moderate enhancement, CT value was 47 -66 HU. At the delay of continuing to strengthen phase, CT value was 60 - 78 HU. The pathology charaters showed that： Diffuse of tumor cells under light microscope dense, more uniform size, and a large, granular chromatin, tumor stromal components was relatively small. There was no significant bleeding, necrosis and calcification, one lesion showed sheet, tumor cell necrosis. Conclusions CT scan characteristics and pathological features of primary adrenal lymphoma might have a certain correlation.
