Arteriovenous malformation (AVM) is defined as a convolute of abnormally connected arteries and veins, where the capillary bed is missing. Intracranial cerebral AVMs are 20 times more common than extracerebral. Focal lingual artery AVMs, especially at carotid bifurcation are rarely reported in the literature. Magnetic resonance imaging, angiography, digital subtraction angiography are the current modalities of diagnosis. Surgical resection can be an effective treatment for vascular malformation; however, the potential for large volume blood loss poses a challenge. In addition, the inability to identify the surgical margins of the nidus can result in recurrence. Present case was diagnosed based on radiological imaging as lingual AVM at the bifurcation of carotid artery. The paper discusses the case of a AVM of the tongue in a 23-year-old female patient at the level of carotid bifurcation. The paper further discusses the various imaging modalities used to diagnose the condition and review the latest literature on the current management concepts. Utmost care needs to be exercised when AVMs are suspected. Radiological investigations are must to know the location and extent of the lesion before attempting surgical intervention like biopsy or excision, which poses life-threatening complications like massive hemorrhage and damage to vital structures.

“…Clinical condition progress as a result of shunting of blood between high pressure arteries low pressure veins. [5][6][7] A number of cases of AVMs have been described by different authors. 81 cases of head and neck AVMs were reported by Kohout et al The most of AVMs are found in cheek (31%), ear (16%), and nose (10%).…”

“…Coils, including stainless steel coils, platinum coils or detachable coils, are typically used as one of the most common embolization agents to embolize the AVMs alone, to embolize the expanded tortuous reflux veins or to eliminate the AVMs combined with absolute ethanol or other embolization agents (3).…”

Coils are typically utilized as one of the most popular embolization agents. Coil migration to the pulmonary artery rarely occurs and is associated with a high tendency of severe pulmonary or cardiovascular complications. We herein present a 25-year-old man with arteriovenous malformations in the right ear. Two coils 4-mm in diameter and 3-mm in length migrated to the pulmonary artery during embolization. No further damage related to the coil migration was found during a 2-year follow-up period. In addition, the possible mechanisms of coil migration are discussed.

“…With its progression, AVM is capable of destroying normal tissues and can lead to complications, for instance severe disfigurement, unmanageable bleeding, ulceration, pain and cardiac volume overload. 5 Initially lesions are recognized based on the prevailing vascular structure involved-arterial, venous, lymphatic, or capillary, considering arterio-venous shunting and also the combined vascular defects. The embryological background of the lesion is then considered for additional demarcation.…”
