Abstrakt: We report two patients with ventilation-perfusion (V-P) images that demonstrate large symmetric perfusion defects with normal chest radiographs and ventilation images who did not have pulmonary embolism (PE) by angiography. This experience suggests that patients with symmetrical V-P mismatches should not be assumed to have PE. The need for pulmonary angiography in such patients should be carefully considered.
