Pulmonary arteriovenous malformation associated with necrotizing fasciitis of the thigh.

Pulmonary arteriovenous malformation (PAVM) is a rare condition often associated with hereditary hemorrhagic telangiectasia. The association between PAVMs and brain abscesses has been previously reported, but abscesses at other locations are extremely rare. We present a 51-year-old woman with PAVM (without signs of hereditary hemorrhagic telangiectasia) and necrotizing fasciitis of her thigh and discuss the possible relationship between the 2 disorders.
