We report a case of bronchial Dieulafoy's disease in the pediatric age. Angio-computed tomography scan and arteriography addressed us to diagnosis. Bronchial endoscopy with biopsy was avoided due to the high risk of developing a life-threatening hemorrhage. Transcatheter embolization of the bleeding bronchial artery was achieved with a MicroPlex

10 HyperSoft 3D 3.5 mm × 80 mm System (MicroVention, Tustin, CA, USA). Dieulafoy's disease is an extremely rare lesion in the pediatric age, and the small diameter of the bleeding vessels may complicate the percutaneous approach with procedural failure. Currently, the novel thin and soft detachable coils allowed to widen the transcatheter embolization in the pediatric age.
