Reversibility of complete unperfusion in a patient with recurrent hemoptysis.

We present a case of a 68-year-old woman with a history of mild smoking and chronic bronchitis who showed recurrent hemoptysis. She presented with a nearly normal chest roentgenogram, a non-diagnostic fiberoptic bronchoscopy and a computed tomography and lung scanning both of which were highly suggestive for malignancy. In fact, the former showed obstruction of the main left bronchus, of the superior bronchus for the left upper lobe and of the apical bronchus for the left lower lobe, the latter showed a total cessation of blood flow through the left lung. Pulmonary angiography, however, was normal and aortography showed dilatated and twisted left bronchial arteries. Computed tomography and lung scanning came back to normal after bronchoscopic aspiration of endobronchial clots and a nonspecific antibiotic therapy were carried out. Although very infrequent, bronchial stenosis on CT and complete monolateral unperfusion on lung scintigraphy may occur in patients with hemoptysis of benign origin. We recommend the use of pulmonary arteriography in patients with the above pattern when diagnostic doubt remains after bronchoscopy.
