Arteriovenous malformation of head and neck is a rare vascular anomaly but when present, it is persistent and progressive in nature. It can also represent a lethal benign disease due to massive hemorrhage. There are several indications for treatment including age, location, extension and type of vascular malformation. Endovascular therapy can effectively cure most lesions with limited tissue involvement. Surgery can be used in selected cases in combination with embolization. Here, we present a rare case of arteriovenous malformation of mandible with floating tooth appearance in an 11-year-old boy patient. Given the spectrum of imaging presentations seen and the crossover with other lesions, microscopic histopathological examination is the gold standard for diagnosis.
头颈部动静脉畸形是一种罕见的血管异常，但一旦出现，其本质上具有持续性和进展性。由于大量出血，它也可能是一种致命的良性疾病。治疗的指征有几个，包括血管畸形的年龄、位置、范围和类型。血管内治疗可以有效治愈大多数组织受累有限的病变。手术可用于部分选定病例，并结合栓塞治疗。在此，我们报告一例11岁男性患者罕见的下颌骨动静脉畸形，表现为牙齿浮动。鉴于所观察到的影像学表现范围以及与其他病变的交叉情况，微观组织病理学检查是诊断的金标准。
