问题 单项选择题 A2型题

男性患者,54岁,5年前体检时腹部B超发现左肾一个孤立性占位病变,呈囊状,当时未给予任何治疗。5年间随诊观察,占位病变生长缓慢。近半年,常有局部不适和尿路感染症状。手术切除病变。病理检查见一直径4cm的囊性病变,囊壁薄,内含黄色透明液体。显微镜下:囊肿压迫周围正常肾组织,囊壁内衬单层不连续的上皮细胞。其诊断应为()

A.髓质海绵肾

B.囊肿性肾发育不良

C.成人型多囊肾

D.婴儿型多囊肾

E.单纯性肾囊肿

答案

参考答案:E

解析:囊肿性肾发育不良多见于新生儿和儿童,病理上应有原始的小管和化生软骨。髓质海绵肾十分罕见,外观像海绵,大部分为双侧肾发病。成人型多囊肾,一般呈现多个囊肿,各囊肿见有少量相对正常肾组织。婴儿型多囊肾幼儿发病。因此病例为单纯性肾囊肿。
