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.

下颚动静脉瘘:病例报告。
骨内动静脉畸形(AVM)是一种不常见的高流量血管畸形,可影响上颌骨或下颌骨。动静脉畸形可能表现为不特异和误导性的体征和症状。诊断往往是偶然的,出血可能是首发症状。从影像学角度看,其特征很少,很容易误诊。在此,我们报告了一例下颌骨右侧动静脉瘘的年轻男性患者,起初被误诊为囊性病变。患者接受了血管畸形经动脉栓塞术,随后手术切除了病灶。1年的随访显示,下颌骨完全愈合,没有复发。骨内动静脉畸形十分罕见。然而,由于其危害性,临床医生和放射科医生都必须警惕这类病变,并应始终将其纳入溶骨性病变的鉴别诊断中。

期刊介绍: As the official English-language journal of the Japanese Society for Oral and Maxillofacial Radiology and the Asian Academy of Oral and Maxillofacial Radiology, Oral Radiology is intended to be a forum for international collaboration in head and neck diagnostic imaging and all related fields. Oral Radiology features cutting-edge research papers, review articles, case reports, and technical notes from both the clinical and experimental fields. As membership in the Society is not a prerequisite, contributions are welcome from researchers and clinicians worldwide.
