Arteriovenous malformations are uncommon congenital lesions of the hand. Although present at birth, they usually manifest later in life. Ultrasonography, MRI and digital subtraction angiography play an important role in the diagnosis of these lesions. We report the imaging appearances of an unusual case of combined soft-tissue and intraosseous arteriovenous malformation (AVM) of the hand with marked periosteal elevation in a 12-year-old child. Although associated skeletal changes are common, diffuse periosteal elevation owing to direct communication of the AVM with the subperiosteal space has not, to the best of our knowledge, been reported previously.
