AB The  term  pulmonary  arteriovenous  malformation  (AVM)  refers  to  lesions  that  have  abnormal  communications  between  the  pulmonary  arteries  and  pulmonary  veins.  Numerous  other  names  such  as  pulmonary  telangiectasias,  aneurysms,  fistulas,  hemangiomas,  and  cavernous  angiomas  have  also  been  used  to  describe  these  lesions.  These  lesions  can  be  congenital,  usually  as  part  of  the  hereditary  hemorrhagic  telangiectasia,  also  known  as  Rendu–Osler–Weber  syndrome,  or  acquired  from  bronchiectasis,  infections,  hepatic  cirrhosis,  mitral  stenosis,  malignancies,  or  trauma.  AVMs  have  been  described  based  on  number  (single  vs.  multiple),  location  (unilateral  vs.  bilateral,  parenchymal  vs.  pleural),  and  size  or  type  of  drainage  (simple  vs.  complex).1,2  These  lesions  are  quite  rare  with  an  unknown  incidence.  Modern  lung  cancer  screening  chest  CT  scan  series  report  an  incidence  of  1:2600  patients.3
