Moderate hemoptysis of unknown etiology

Abstract

The underlying cause and treatment of hemoptysis should be addressed promptly to avoid potentially life‐threatening complications. We report on a previously healthy 11‐year‐old white boy who presented with acute hemoptysis. On bronchoscopy, bleeding was noted from the right upper and lower lobes. Right bronchial arteriography revealed multiple regions of abnormal “blushing” throughout the right bronchial arterial distribution which was successfully controlled by right bronchial arterial embolization. In spite of an extensive work‐up, we were not able to determine the cause of bleeding. The patient has been followed for 18 months without any recurrence and without evidence of any systemic disease. Our patient does not fit any diagnostic category of pulmonary bleeding and further case reports are needed to delineate this entity. Pediatr Pulmonol. 1999; 27:351–355. © 1999 Wiley‐Liss, Inc.
