The clinical features suggestive of PAVMs are stigmata of right-to-left shunting (dyspnea, hypoxemia, cyanosis, cerebral embolism, brain abscess), unexplained hemoptysis, or hemothorax.<br>We present a case of young man presented to Emergency Department complaining dyspnea, polycythemia and persistent hypoxemia. Angio-CT scan of the chest detected multiple PAVMs.<br>PAVMs are uncommon in the general population, but they are an important consideration in the differential diagnosis of common pulmonary problems, including hypoxemia, pulmonary nodules, and hemoptysis</p>}, number={4}, journal={Italian Journal of Medicine}, author={Brugioni, Lucio and Catena, Chiara and Ferraro, Eugenio and Scarabottini, Serena and Mori, Francesca and Clini, Enrico}, year={2019}, month={Nov.}, pages={244–246} }
