Arteriovenous malformations (AVMs) are an abnormal communication between arterial and venous structures. Pelvic AVMs have been infrequently described in the literature and represent an uncommon cause of a palpable pelvic mass.
A case of pelvic AVM with ureteral obstruction occurred. The location and radiologic appearance of the AVM suggested a complex adnexal mass. During exploration and resection of the mass, significant bleeding was encountered. The diagnosis of AVM was made only retrospectively, with histologic examination of the specimen.
AVMs are an uncommon and unique cause of pelvic pathology. Preoperative diagnosis will alert the surgeon as to the technically difficult resection that may be encountered and to the massive bleeding that can be associated with their removal.
动静脉畸形（AVM）是动脉和静脉结构之间的异常交通。盆腔动静脉畸形在文献中鲜有描述，是可触及盆腔肿块的罕见原因。
发生了一例伴有输尿管梗阻的盆腔动静脉畸形。动静脉畸形的位置和放射学表现提示为复杂附件肿块。在对肿块进行探查和切除时，遇到了大量出血。仅在对标本进行组织学检查后才做出动静脉畸形的回顾性诊断。
动静脉畸形是盆腔病变的罕见且独特的原因。术前诊断将提醒外科医生注意可能遇到的技术上困难的切除以及与切除相关的大量出血。
