TLDR A man had temporary hair loss from radiation during a medical procedure but regrew his hair after treatment with minoxidil lotion.
In 2016, a 46-year-old man developed radiation-induced alopecia after an endovascular embolization procedure using fluoroscopy. He exhibited a distinct alopecic patch on his scalp, with dermoscopic examination showing unique patterns of blue-grey and yellow dots. A biopsy indicated an increase in catagen and telogen hairs but no perifollicular infiltration. Despite the radiation exposure being 2.9 Gy, which is below the threshold for causing temporary hair loss, the patient experienced alopecia. However, the condition was temporary, and he saw complete hair regrowth within 4 months after using 5% minoxidil lotion twice daily. This case underscores the need to consider radiation-induced hair loss in similar clinical scenarios and to minimize radiation exposure during fluoroscopic procedures.
