There is no single reported case on inflammatory pulmonary arterio-venous malformation (PAVM) which resolves completely without any intervention. We are the first to report a case in which an inflammatory PAVM achieved complete resolution without any treatment. A 62 years old gentleman presented with gradual worsening dyspnoea on exertion and haemoptysis after aspirated oral contrast. On investigation, contrast enhanced computated tomography scan revealed a right lower lobe arterio-venous malformation. However, after a few months, a follow up CT was performed and it revealed a complete resolution. Conservative management approach for inflammatory PAVM can be taken at the initial stage because complete resolution is possible in some cases. However, a close monitoring is required to ensure a complete resolution.
