Temporary alopecia after embolization of an arteriovenous malformation.

Alopecia after head and neck radiotherapy has been extensively reported in the literature. However, alopecia after endovascular procedures is seldom reported in the dermatological literature. Prolonged fluoroscopic imaging during these procedures may cause serious radiation injuries to the skin, such as dermatitis or alopecia. Radiation-induced temporary alopecia is a peculiar form of radiodermitis that occurs over the areas of the scalp that receive the highest doses of radiation. Although repopulation of alopecic patches occurs spontaneously without treatment, it is important to recognize this disorder to establish a correct diagnosis and inform patients about this transient side effect. We report a 44-year-old woman presenting with temporary alopecia after embolization of an arteriovenous malformation.
