A patient with a large left-sided arteriovenous malformation underwent superselective angiography and therapeutic embolization. Sixteen days later he presented with an acute anagen-dystrophic hair loss localized to the occipital and right parietal regions corresponding to the irradiated scalp area. The diagnosis of an acute radiation injury to the hair follicle from prolonged fluoroscopic imaging during the interventional neuroradiologic procedure was made. This reversible side effect occurs typically after single short-term exposures of 300-400 cGy. Above single doses of 1200 cGy, the epilation is permanent. Patients have to be informed about the possibility of this reversible complication, which must be distinguished from alopecia areata, postoperative ischemic pressure alopecia and drug toxicity.
一名患有左侧大型动静脉畸形的患者接受了超选择性血管造影和治疗性栓塞。16天后，他出现了急性生长期营养不良性脱发，脱发部位局限于枕部和右侧顶叶区域，与照射的头皮区域相对应。诊断为介入神经放射学手术期间长时间透视成像导致毛囊急性辐射损伤。这种可逆的副作用通常在单次短期暴露于300 - 400 cGy后出现。单次剂量超过1200 cGy时，脱发是永久性的。必须告知患者这种可逆并发症的可能性，它必须与斑秃、术后缺血性压迫性脱发和药物毒性相区分。
