“…In the absence of information on a recent endovascular intervention, radiation-induced temporary alopecia is difficult to distinguish from AA because of the similar clinical manifestations. [ 2 3 ] The dermoscopic findings revealed yellow dots, black dots, and short vellus hairs in this study, all of which are a common feature of AA. [ 12 16 ] The histopathologic finding of sparse perifollicular inflammatory infiltrate in a patient with a strongly positive hair-pull test may be helpful in the differential diagnosis as intensive perifollicular infiltration occurs in the acute stage of AA.…”

“…It is called as various terminology, including radiation-induced temporary alopecia, transient rectangular alopecia, and square alopecia. [ 1 3 4 ] Radiation-induced temporary alopecia might occur in cases of radiation exposure ranging from 3 to 6 Gy, but the risk of permanent alopecia is high if the radiation dose exceeds 7 Gy. [ 1 5 ] According to the International Commission on Radiological Protection,[ 6 ] approximately 7% of endovascular interventions reach the threshold for radiation-induced temporary alopecia.…”

Three cases of radiation-induced temporary alopecia with hair microscopic examination: “coudability hair” might not be specific for alopecia areata

et al. 2018

Endovascular interventional procedures are widely used for the treatment of intracranial vascular lesions. However, they sometimes produce reversible alopecia, known as radiation-induced temporary alopecia, depending on the radiation dose. Radiation-induced temporary alopecia manifested as rectangular alopecic patches without signs of inflammation, reflects damage to the keratinocytes in the hair matrix of anagen hair follicles, due to the sensitivity of these cells to radiation. The characteristics of radiation-induced temporary alopecia are similar to those of alopecia areata as follows: (1) clinical findings of well-defined alopecic patches and (2) dermoscopic findings of yellow dots, black dots, and short vellus hairs. The two conditions can be distinguished according to whether there is any history of endovascular interventional procedures, and by the shapes of the lesions and the inflammation status on histopathologic examination. A hair microscopic examination is a useful diagnostic tool in patients with hair loss disease, but the features of radiation-induced temporary alopecia have not been well described. Here, we report three cases of radiation-induced temporary alopecia preceded by endovascular procedures, including stent insertion and coil embolization.

“…In previously reported cases, temporary alopecia over the temporoparietal and occipital areas has occurred in interventional neuroradiological procedures involving therapeutic embolization of cerebral arteriovenous malformations and brain circulation aneurysms. Complete spontaneous hair regrowth generally occurred 2–6 months after irradiation and in some patients, the irradiation-induced epilation was misdiagnosed as alopecia areata [6,7,8,9,10,11,12,13,14,15]. Our patient presented with a deep scalp ulceration surrounded by poikilodermatous and persistent alopecic area after a single procedure for the endovascular coiling of an anterior circulation aneurysm.…”

“…The most common entrance sites of ionizing radiation associated with cardiac procedures are the scapula, back and lateral trunk under the axilla. Other common locations are the left flank (associated with mesenteric artery angiography and stent placement), the back (associated with TIPS) and the temporoparietal and occipital areas of the scalp (associated with neurovascular embolization) [1,2,5,6,7,8,9,10,11,12,13,14,15]. For most patients, clinically significant skin and hair reactions are thought to occur when the skin dose is >5 Gy.…”

Chronic Scalp Ulceration as a Late Complication of Fluoroscopically Guided Cerebral Aneurysm Embolization

2012

Fluoroscopy-induced chronic radiation dermatitis resulting from prolonged exposure to ionizing radiation during interventional procedures has been documented in the medical literature. However, this condition often requires a high clinical suspicion in order to establish a correct diagnosis. In this report, the development of deep scalp ulceration with bone exposure following the endovascular coiling of an anterior communicating artery aneurysm 8 years before is described. A skin biopsy specimen demonstrated changes consistent with chronic radiation dermatitis and ruled out malignancy. This case report expands the clinical manifestation spectrum of fluoroscopy-induced chronic radiation skin injury and highlights the importance of recognizing these lesions early to prevent morbidity related to radiation-induced skin damage.

Square alopecia: A new type of transient alopecia of the scalp following fluoroscopically endovascular embolization

et al. 2013

Endovascular interventional procedures are the first choice of treatment for many vascular intracranial lesions, especially those with complex anatomy. These procedures may cause numerous skin lesions depending on the dose of radiation to which patients have been exposed. In this report, we presented a case of a 38-year-old man who developed a square plaque of alopecia in the occipital area after two selective embolization of a left posterior parasagittal arteriovenous malformation. The alopecia was transient and the hair grew up 2 months later after the last procedure. This case illustrates one of the effects of radiation on the scalp and expands our knowledge about the clinical manifestation of this transient disease.
