Abstract

Introduction: Pelvic arteriovenous malformations are rare in male patients. We present a case of pelvic arteriovenous malformation involving the seminal vesicle.

Case presentation: A 58-year-old man was diagnosed with pelvic arteriovenous malformation that involved the left seminal vesicle by angiography. The patient underwent three embolization procedures and made favorable progress after the embolizations.

Conclusion: Herein, we report a rare case of pelvic arteriovenous malformation involving the seminal vesicle treated by embolizations with good outcome.

Keywords: angiography; dehydrated ethanol; embolization; pelvic arteriovenous malformation; seminal vesicle.

(a) CT image showing the parapelvic AVM involving the left seminal vesicle. (b) Arterial phase angiographic image of the AVM with multiple feeding vessels arising from branches of the left internal iliac artery. (c) Venous phase angiographic image of the AVM, demonstrating a drainage vessel connected to the left iliac vein.

(a) Arterial phase angiographic image highlighting the two main feeding arteries originating from the left iliac artery (indicated by yellow arrows). (b) Angiographic image of the two main feeders before treatment. The arrow indicates the area to be embolized. (c) Angiographic image of the feeders after the first treatment, shows the absence of contrast agent downstream of the arrow. (d) The arrow indicates a feeder that was not embolized during the initial treatment. (e) Area injected with ethanol during treatment. (f) Angiographic image revealing the main shunt point, which became apparent after the second treatment.

(c) Angiographic image showing the coils used during the third session. (d) Angiographic image after the third session, where the pAVM is no longer detectable. (e) Contrast‐enhanced CT image of the pAVM after the third session. The pAVM involving the left seminal vesicle is not detectable.
