Pseudostripe sign in lobar collapse.
The stripe sign in perfusion lung scanning refers to an area of focal hypoperfusion that fails to extend to the pleural surface, leaving a peripheral rim of perfused parenchyma. Although experimental evidence suggests that the stripe sign is caused by central pulmonary emphysema, we report a case of an identical perfusion defect related to a completely collapsed left lower lobe. This etiology should be considered in the differential diagnosis of the stripe sign.
