title: Do recurrent pulmonary emboli lodge preferentially in prior foci?
abstract: Two cases of recurrent pulmonary embolism are presented: the perfusion lung scintigrams, having been positive on admission, later showed nearly complete restoration of perfusion. However, during the second episode of pulmonary embolism, which occurred several years later, the perfusion defects were located in the same foci as previously.
