“…The overlying skin feels warmer to touch and a palpable thrill or bruit is often felt. [14] In the present case, there was no discoloration of overlying skin and no local rise in temperature. The lesion was compressible and the lesion appeared in a dependent position.…”

Vascular malformations (VMs) are congenital anomalies of the capillary, venous, lymphatic, and arterial system. They may be distinguished from vasoproliferative tumors (hemangiomas) which present with increased endothelial cell turnover, whereas VMs are structural anomalies of vessels without endothelial cell proliferation. VMs, in general, occur in superficial areas such as lips, tongue, and buccal mucosa, and an intramuscular location is quite rare. An intra-massetric location may be mistaken for a parotid swelling and may also pose problems in terms of proximity to facial nerve. One such rare case of intra-massetric VM occurring in a 23-year-old female with an unusual clinical presentation is being presented in this case report. The patient complained of a swelling associated with pain on her right cheek since 9 months. The swelling develops only when her head and torso is bent to 90° or more for at least 5-10 min and gradually disappears on attaining an upright posture (turkey wattle sign). Color Doppler ultrasonographic findings were suggestive of a VM. The lesion was excised under general anesthesia and was sent for histopathologic evaluation which was suggestive of an intramuscular hemangioma/ malformation. The patient did not develop any post-operative complications and had recovered well after the surgery.

“…[12] Both the lesions are easily compressible. [2,3,7,[14][15][16] Purely venous and purely lymphatic malformations are rare, and they generally occur in combination. Venous malformation has the tendency to expand and contract with the change of patient's posture as it is a dependent lesion.…”

“…High-flow lesions show typical signal flow voids both in T1-weighted and T2-weighted sequences with the appearance of serpentine images. [ 13 ] In the present case, MRI was able to identify the kind of flow, i.e., high flow as well as the origin of the vessels, i.e., external carotid artery.…”

Arteriovenous malformation of face

Arteriovenous malformations (AVMs) are rare congenital vascular malformations accounting only 1.5% of all vascular anomalies with 50% occurrence in the oral and maxillofacial region. It usually results from birth defects of the vasculature. A literature search revealed only few case reports of AVMs in the facial region. Lack of meticulous diagnosis, scarcity of knowledge, and paucity of literature can result in their exsanguinations leading to fatal hemorrhagic incidents after various dental procedures such as tooth extraction, surgical intervention, puncture wound, or blunt injury in involved area. The present case describes the accidental diagnosis of asymptomatic high-flow AVMs in the facial region of pediatric patient reported primarily for the treatment of periapical abscess. This case report is unique because although there was no history of bleeding episodes, thorough examination and investigations diagnosed it as high-flow vascular malformation. It is important for the dental practitioner to be aware of AVM which may be present in the head and neck region that can produce fatal bleeding episodes during various dental procedures. Proper diagnosis of AVMs through complete history, precise clinical examination, and advanced imaging modalities can help in preventing serious life-threatening complications.

High-ow lesions show typical signal ow voids both in T1-weighted and T2-weighted sequences with serpentine images 11 . In the present case, MRI was able to identify the kind of ow, high ow as well as the origin of the vessels which were branches of external carotid artery.…”

Arteriovenous malformations are congenital vascular malformations resulting from birth defects of the vasculature. They account for 1.5% of all vascular anomalies, and 50% of the lesions are located in the oral and maxillofacial region1. Regardless of the type, malformations may lead to significant anatomical, pathophysiological and hemodynamic consequences. Therefore, despite their rarity, AV malformations still remain the most life-threatening form of vascular anomalies. The present case describes the diagnosis of high flow AV malformation in a patient who had repeated hospital admissions for anemia secondary to bleeding from oral cavity with multiple blood transfusions. The case is unique because the cause for recurrent oral bleeding was undiagnosed and through thorough history, examination, investigations, high flow arteriovenous malformation was diagnosed and managed appropriately.
