Pulmonary embolism (PE), a medical emergency for pulmonary physicians, is defined as a blockage of the main artery of the lung or one of its branches by embolism from many sources, such as thrombus, air, amniotic fluid, tumor and fat. A good clinician, especially pulmonary or critical care physician, should consider the possible diagnosis of pulmonary embolism in a highly suspected patient since prompt diagnosis and treatment can dramatically reduce the morbidity and mortality of this disease. Due to the nonspecific signs and symptoms of PE, imaging techniques have been recognized as the major method for physicians in diagnosis. Nowadays, computed tomography pulmonary angiography (CTPA), with high sensitivity and specificity, has become the golden standard in PE diagnosis. Combined application of CTPA and ventilation/perfusion lung scan (V/Q scan) can further yield a definite diagnosis in 90%-99% suspected patients. However, false-positive CTPA manifestation of PE may also mislead physicians in diagnosis. Here, we report a case who was misdiagnosed of PE after radiofrequency catheter ablation (RFCA) because of a combined indication of filling defect on CTPA and VQ scan in left main pulmonary artery, both of which mimic massive PE.
