title: Transient unilateral reverse ventilation/perfusion mismatch in a patient with lung cancer.
abstract: The authors report a transient, unilateral reverse ventilation/perfusion (V/P) mismatch in a patient with squamous cell lung cancer. The right lung was well perfused but not ventilated (unilateral reverse V/P mismatch). However, lung imaging performed 3 days later demonstrated the absence of both perfusion and ventilation (V/P match). Reverse V/P mismatch may be a transient process.
