Infrared thermography of an arteriovenous malformation of the face. a The patient (m, age: 3 years) suffers from an AVM of the left cheek and lower lip. Pink discoloration of the skin is characteristic of the arterial component in this vascular malformation. b Infrared thermography before embolization. Note the locally increased temperature, color-coded as white areas. c Clinical presentation and d infrared thermography immediately after successful embolization. The locally increased temperature is gone. Note a local swelling, induced by the embolization disappearing after a few weeks. AVM is marked with arrow, a more whitish color indicating elevated temperature
