Congenital pelvic arteriovenous malformation (AVM) is a rare vascular abnormality whereby arteries and veins are directly connected with malformed vascular plexus. Owing to its low incidence and nonspecific symptoms, the ultrasonographic characteristics of congenital pelvic AVM in males have been infrequently studied. A 30-year-old man visited our hospital complaining of progressive pain in the right lower abdomen and lumbar area since 2 months previously. Abdominal ultrasound (US) was performed at the initial examination and pelvic AVM was diagnosed, which was then confirmed by computed tomographic angiography. After right internal iliac artery embolization, the patient recovered uneventfully and remained asymptomatic during the 12-month follow-up period. Congenital pelvic AVM should thus be included in the differential diagnosis of pelvic cystic masses in males despite its low incidence, with US also being of great diagnostic value. We describe the ultrasonic features of AVM in detail and hope that this study may contribute to the ultrasonic diagnosis of congenital pelvic AVM in males.
先天性盆腔动静脉畸形（AVM）是一种罕见的血管异常，即动脉和静脉通过畸形的血管丛直接相连。由于其发病率低且症状不具特异性，男性先天性盆腔AVM的超声特征鲜少被研究。一名30岁男性因自2个月前起右下腹部和腰部逐渐疼痛前来我院就诊。初诊时进行了腹部超声（US）检查，诊断为盆腔AVM，随后经计算机断层血管造影证实。右侧髂内动脉栓塞术后，患者恢复顺利，在12个月的随访期内无症状。因此，尽管先天性盆腔AVM发病率低，但在男性盆腔囊性肿块的鉴别诊断中应将其纳入，超声检查也具有重要的诊断价值。我们详细描述了AVM的超声特征，希望本研究有助于男性先天性盆腔AVM的超声诊断。
