Arteriovenous malformations from para-testicular structures are very rare, with only a limited number of cases reported in the literature. The present study reports a rare case of para-testicular arteriovenous malformation. A 6-year-old boy presented with painless swelling in the scrotum for 6 months. Upon examination, a non-tender and non-pulsatile cystic swelling was observed in the right hemi-scrotum below the testis. A scrotal ultrasound revealed a separate cystic lesion with a normal texture and the vascularity of both testes. Under general anesthesia, via a small scrotal incision, a cystic, blood-filled mass was excised. The results of a histopathological examination were suggestive of vascular malformation. The case described in the present study aims to shed light on vascular malformations. A number of vascular malformations are incorrectly referred to as hemangiomas, and numerous patients undergo inappropriate therapy due to this misclassification. Although para-testicular arteriovenous malformation is a very rare condition, it should be included in the differential diagnosis of para-testicular lesions.
