Giant Congenital Pelvic AVM Causing Cardiac Failure, Diplegia, and Neurogenic Bladder

BACKGROUND: Pelvic arteriovenous malformations (AVMs) are uncommon lesions and only a rare number of male cases have been reported. Their clinical presentations are variable and imaging modalities have an important place in diagnosis and treatment planning. CASE REPORT: We present the imaging findings of a giant congenital pelvic AVM that was diagnosed in a 30-year-old male patient eight years ago and which progressed despite follow-up and treatment, causing cardiac failure, diplegia, and neurogenic bladder. CONCLUSIONS: Pelvic AVMs are uncommon lesions and they can present with various symptoms based on their locations and sizes. Delays in the diagnosis and treatment can cause local and systemic complications. Imaging is very important in the diagnosis of pelvic AVM.
