radiation-induced alopecia alopecia cerebral arteriovenous malformation radiosurgical interventions embolization radiation exposure

TLDR Temporary hair loss can occur after brain AVM treatment but usually regrows in 8 weeks.

The document reported a case of temporary radiation-induced alopecia following the embolization of a cerebral arteriovenous malformation (AVM). The patient, who underwent multiple radiosurgical interventions and a final embolization procedure, developed two patches of hair loss approximately 4 weeks post-procedure. The total radiation dose was estimated at 3.92 Gy. Physical examination revealed large circular areas of alopecia without erythema or dermatitis. Hair regrowth was observed 8 weeks later without any treatment. The study highlighted the importance of monitoring radiation exposure to prevent such adverse effects, as no successful therapy for radiation-induced temporary alopecia existed.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 3 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

community Everyone is ignoring that plasma finasteride levels are 100x lower with topical compared to oral.
