Temporal bone changes are described in a 57-year-old man who had sudden onset of dizziness and unilateral deafness two months before death. The patient suffered from hypertension, and congestive and renal failure. At autopsy, subarachnoid hemorrhage with punctate cortical hemorrhages and arteriolar thickening involved the right superior cerebellar hemisphere. The pathological changes involved primarily the right cochlea, saccule and posterior ampulla, and were consistent with vascular embarrassment of the temporal bone of two months duration. The cochlea demonstrated total loss of the organ of Corti and severe degenerative changes of the stria vascularis, spiral ligament, outer sulcus cells and distal cochlear nerve fibers. The saccule demonstrated loss of its macula and nerve fibers. The posterior ampulla showed evidence of previous rupture of its membranous wall with fibrosis and beginning bone formation. Fresh hemorrhage, present in some areas of both temporal bones, was related to the patient's terminal subarachnoid hemorrhage.
本文描述了一名57岁男性颞骨的变化情况，该患者在死亡前两个月突然出现头晕和单侧耳聋症状。患者患有高血压、充血性心力衰竭和肾衰竭。尸检发现，蛛网膜下腔出血伴点状皮质出血和小动脉增厚累及右小脑上半球。病理变化主要累及右耳蜗、球囊和后半规管，与持续两个月的颞骨血管窘迫相符。耳蜗显示柯蒂氏器完全丧失，血管纹、螺旋韧带、外沟细胞和耳蜗远端神经纤维出现严重退行性改变。球囊显示其黄斑和神经纤维丧失。后半规管显示其膜壁先前破裂，伴有纤维化和开始的骨形成迹象。双侧颞骨某些区域出现的新鲜出血与患者终末期蛛网膜下腔出血有关。
