[Pulmonary embolism: a clinical case documented, in acute setting, using pulmonary scintigraphic perfusion]

The acute clinical evolution is presented of a patient with previous myocardial infarction who was admitted for dyspnea and chest pain. Acknowledging the possibility of a new ischemic event, confronted with aortic dissection or pulmonary embolism, the clinical investigation is described up to the scintigraphic diagnosis of pulmonary embolism. The clinical presentation, diagnostic investigation and therapeutic decisions are discussed, with emphasis on the usefulness of pulmonary scintigraphy.
