中山大学附属第三医院
主诉 病史
患者男49岁,因“健康体检时超声扫查意外发现右侧肾上腺占位性病灶”入院。
查体 复查
入院查体未见明显异常。生命体征平稳。
B超示:右侧肾上腺有3 枚明确的圆形低回声结节,大小相近 均在10~15 mm,左侧肾上腺也可见1 枚椭圆形的类似低回声结节,略大。
血清钾、钙、磷测值均正常。
促肾上腺皮质激素ACTH、皮质醇、醛固酮水平及分泌节律均属常态。
血清肾上腺素、去甲肾上腺素及尿香草扁桃酸、VMA检查未吉安明显正常。
诊断 治疗
术前诊断:双侧肾上腺无功能性皮质腺瘤,右侧呈多发性。
予完善相关术前检查,查无明显手术禁忌,予先行右侧病灶腹腔镜下摘除,左侧随访观察。
病理诊断:多发性肾上腺皮质腺瘤。
随访 处理
肾上腺皮质依细胞的排列形态由外向内分为球状带、束状带和网状带3个区带的细胞分别合成和分泌醛固酮、皮质醇和性激素。发生在相应区带内的良性腺瘤因分泌过剩激素引起临床症候群称之为功能性腺瘤。少部分腺瘤分泌激素的能力不强 临床上无相应的症状和体征称之为无功能腺瘤。导致这种内分泌激素活性显著差别的原因尚不明了。但是却决定了无功能腺瘤主要是在影像学检查时被意外发现 故又可称之为肾上腺偶发瘤。无功能腺瘤可以长期保持无或极低内分泌功能状态也可以转化成内分泌功能活跃的腺瘤 瘤体可以数年内无增大。如果在定期随访过程中发现突然增大则需警惕。及时手术干预。因为不排除转移癌被漏诊的可能。
