We report on the pathological findings in temporal bones taken from a 92-year-old man who had been diagnosed as suffering from Cogan's syndrome before death. Extensive endolymphatic hydrops was observed in the cochlea of the right ear. The saccule showed a collapse following intense dilation. Outpouching of the utricle and crus commune was found and the perilymphatic space of the posterior semicircular canal was occupied by the fibrotic tissue. The left ear showed neither hydrops nor fibrosis. There was absorption of the enchondral bone in both ears, but in the blood vessels there were no pathological changes.
我们报告了一名92岁男性颞骨的病理检查结果，该男性生前被诊断患有科根综合征。右耳耳蜗内观察到广泛的内淋巴积水。球囊在强烈扩张后出现塌陷。发现椭圆囊和总脚有憩室，后半规管的外淋巴间隙被纤维组织占据。左耳既没有积水也没有纤维化。双耳均有软骨内骨吸收，但血管未见病理改变。
