We describe a 20-year-old male patient who presented with gingival bleeding. Physical examination showed gingival swelling of the right maxilla and loosening of the molar teeth. The initial diagnosis of gingivitis was made, but further examination revealed a lytic lesion of the maxilla. On suspicion of fibrous dysplasia, biopsy was attempted but was unsuccessful due to severe haemorrhage. Further evaluation showed palpable and audible bruit on the gingiva, which caused the suspicion of vascular malformation. Angiography was performed and demonstrated arteriovenous malformation (AVM). Embolisation therapy with polyvinyl alcohol was performed. Post-embolisation angiogram demonstrated complete obliteration of the lesion.
