TY - JOUR AU - Deorari,, V AB - A young gentleman presented to our clinic with gradually progressive enlargement of his whole right upper extremity since 5 years, along with multiple reddish patches since childhood. On examination, there was a definite asymmetry noted between his upper extremities (Figure 1A). His muscle bulk and power were greater in the right upper limb than the left. There was a palpable thrill and a loud audible bruit was heard over the right infraclavicular area. CT angiography with dual-energy bone-removal study revealed massive dilatation of the right upper limb arteries (Figure 1B, arrow) along with increased bulk and enhancement of right upper limb muscles showing multiple small vascular channels within likely arteriovenous fistulae. Apart from this, no other vascular malformations were found in any other part of the body. A diagnosis of Parkes Weber syndrome was made. An opinion of the multidisciplinary team consisting of dermatologist, vascular surgeon and interventional radiologist was taken and it was decided to manage the patient conservatively as he was asymptomatic and the enlarged limb did not affect his activities of the daily living.
