Dyspnea that worsens when sitting upright and resolves when recumbent (platypnea) is unusual and suggests pulmonary arteriovenous malformation or the hepatopulmonary syndrome; it may also occur after pneumonectomy, in recurrent pulmonary embolism, and in chronic pulmonary diseases that preferentially affect the lower lobes, such as aspiration pneumonia and α
