本文报告七例自发性、外伤后、亚急性及慢性脑内血肿引起的环状潮红。随着血肿年龄的增长，造影剂增强后可以看到环形红晕。连续CT显示，在第一次扫描后两到六个月，环红消失。环状红晕的CT表现并非血肿的特异性表现，但其外周位置和无占位效应可被视为血肿的提示，并具有适当的临床表现。在大多数情况下，特征性的连续变化允许正确诊断而无需手术干预。
Seven cases of ring blush following spontaneous and post-traumatic, subacute and chronic intracerebral hematoma are presented. As such a hematoma ages, a ring blush may be seen following contrast-agent enhancement. Serial CT demonstrates disappearance of the ring blush from two to six months after the first scan. The CT appearance of the ring blush is not specific for hematoma, but its peripheral location and lack of mass effect may be considered suggestive of hematoma with appropriate clinical findings. The characteristic serial changes permit correct diagnosis without surgical intervention in most cases.
