目的分析后肾腺瘤的分类及命名,临床、病理及影像学表现.方法对1例经病理证实的后肾腺瘤,结合文献中资料较为完整的20例患者进行综合分析.结果后肾腺瘤肿块体积较大,直径多>5 cm.均单侧发病.临床可伴有红细胞增多症.静脉肾盂造影示肾脏分泌功能存在.CT平扫肿瘤呈稍低或等密度,可伴斑点状钙化,部分可囊变;增强病灶轻到中等度强化,中央可有纤维瘢痕组织.肿瘤本身具有恶变潜能及局部淋巴结转移.病理学特点:后肾腺瘤细胞均匀一致、胞浆少,无明显异型性,核分裂像罕见;免疫组化:WT1(+)、AMACR(-).结论后肾腺瘤临床及影像学表现特征不明显,最终诊断有赖于病理学检查.

Objective To analyse the classification and naming,clinic,pathology and imaging features of metanephric adenoma. Methods 1 case with pathologically confirmed metanephric adenoma in combination with 20 cases in the literatures were comprehensively analysed . Results The volume of metanephric adenomas were mostly larger(>5 cm in diameter). The tumors were all unilateral. The lesions might be accompanied by erythrocytosis. Intravenous pyelography showed the existence of the secretory function of the kidneys. CT scan showed that the tumors were slightly hypo-or iso-dense,might be associated with punctate calcification and partially cystic degeneration or fibrous scar tissue in the centre of the tumors. The lesions were light to moderate degree of enhancement at contrast- enhanced scan. There was potential of malignant changing of the tumor itself and the local lymph node metastasis. The pathological features were:metanephric adenoma cells uniform,less cytoplasm,no atypia,rare mitotic phase. Immunohistochem-istry showed:WT1( + ), AMACR( - ). Conclusion The clinical and imaging features of metanephric adenoma are not special,the final diagnosis depends on histopathological examination.
