Bronchial artery embolization (BAE) is currently the first-line treatment for massive hemoptysis. Previous studies have proven its safety and efficacy, with mild, transient, and reversible complications. This case described a patient with congenital multiple bronchopulmonary fistulas who underwent BAE due to massive hemoptysis. However, due to an overlooked and misdiagnosed atypical fistula, the patient experienced an ectopic pulmonary embolism and subsequently secondary pulmonary infarction. He eventually exhibited a full postoperative recovery following percutaneous catheter-directed embolectomy. This case revealed a type of occult fistula masked by multiple bronchial artery branches, which may be a potential risk factor for an ectopic pulmonary embolism during BAE. We propose that it is crucial to identify abnormal anastomosis, especially atypical fistula, and select appropriate embolization materials during BAE.
