Abstract：
Intraosseous arteriovenous malformations (AVM) are uncommon high-flow vascular malformation that can affect the maxilla or mandible. AVM may present with aspecific and misleading signs and symptoms. The diagnosis is often accidental and bleeding may represent the first symptom. Radiographically, there are few characteristic features and misdiagnosis is easy. Here we report the case of a young male affected by arteriovenous fistula on the right side of the mandible initially misdiagnosed as a cystic lesion. The patient underwent transarterial embolization of the vascular malformation and subsequently the lesion was surgically removed. 1-year follow-up showed complete healing of the mandibular bone and absence of recurrence. Intraosseous arteriovenous malformations are rare entities. However, due to their harmfulness, both clinicians and radiologists must be aware of this type of lesion and should always consider them in the differential diagnosis of osteolytic lesions.
摘要：
骨内动静脉畸形（AVM）是罕见的高流量血管畸形，可影响上颌骨或下颌骨。AVM可能会出现特异性和误导性的体征和症状。诊断通常是偶然的，出血可能是首发症状。射线照相,特征性特征少,易误诊。在这里，我们报告了一例年轻男性，该男性在下颌骨右侧受到动静脉瘘的影响，最初被误诊为囊性病变。患者接受了血管畸形的经动脉栓塞，随后手术切除了病变。1年随访显示下颌骨完全愈合，无复发。骨内动静脉畸形是罕见的实体。然而,由于它们的危害性，临床医师和放射科医师都必须意识到这一类型的病变,在进行溶骨性病变的鉴别诊断时,应始终考虑这一类型的病变.
