The authors illustrate the importance of lung ventilation and perfusion scintigraphy in demonstrating endobronchial lesions in a 49-year-old woman, in whom ovarian cancer was diagnosed 2 years earlier, who had shortness of breath. Pulmonary embolic disease was suspected. Initial chest films were interpreted as normal. However, Xe-133 ventilation and Tc-99m MAA perfusion images were abnormal and suggested an obstructing right mainstem bronchial lesion. Subsequent CT of the chest confirmed a large right subcarinal mass invading the bronchus which was shown on bronchoscopy to be metastatic ovarian cancer. This is the sixth reported case of bronchial metastasis of ovarian carcinoma and the only one detected by scintigraphy.
