We report the case of a middle-aged man presenting with dystrophic, thickened yellow nails; an idiopathic pericardial effusion in the absence of pleural effusion(s); and unilateral apical bronchiectasis found on computed tomography of the chest. This represents a unique presentation of YNS as the first report of a patient with YNS and a pericardial effusion in the absence of pleural effusions and lymphedema and is the 11th case report of YNS with pericardial effusion.
