Recurrence of Pulmonary Arteriovenous Malformation with Non-tuberculous Mycobacteria Infection Caused by Perfusion from the Pulmonary Artery and Bronchial Artery after Coil Embolization

A 28-year-old man with a history of coil embolization of multiple pulmonary arteriovenous malformations presented with hemoptysis 11 years after initial embolization. A cavity lesion in the left upper lobe, which was accompanied by deformed coils and ground-glass opacity, was considered responsible for hemoptysis. Embolization of the bronchial artery was performed.

Pulmonary arteriovenous malformation (PAVM) is a rare vascular anomaly, for which transcatheter embolization with metallic coils is the standard of care. Although detecting recanalization after embolotherapy is crucial, direct visualization of residual flow with computed tomography or magnetic resonance (MR) imaging is generally difficult due to metal artifacts. We present a case of recanalized PAVM after coil embolization detected by ultra-short echo time MR angiography using a modified signal targeting with an alternative radio frequency spin labeling technique.

Introduction: Pulmonary arteriovenous malformation (PAVM) is a rare anomaly, mostly congenital, that tends to increase in size with the influence of various factors. Case report: A primigravida at 37 weeks of gestation presented with acute onset of dyspnea due to right sided hemothorax. Computed tomography showed abnormal vessels with pseudoaneurysm in the right lower lobe and shunting between subsegmental branch of right descending pulmonary artery and right inferior pulmonary vein. Embolization of the lesion was planned after immediate cesarean section. Coil embolization with complete occlusion of supplying artery of the lesion was done. Conclusion: PAVM, although rare can result in fatal complications if untreated. Less invasive image guided coil embolization is a promising treatment modality.
