title: Inapparent pulmonary vascular disease in an ex-heroin user.
abstract: A severe pulmonary vascular derangement, usually reported in drug addicts, was diagnosed in a 28-year-old asymptomatic ex-heroin user by means of fortuitously performed pulmonary perfusion imaging. Neither physical findings nor pulmonary function tests, aroused suspicion of the diagnosis. A search for asymptomatic pulmonary vascular disease probably should be undertaken in drug addicts.
