Arteriovenous malformations (AVMs) are rare disorders, with inguinal region involvement being particularly uncommon, as they typically manifest in the neck, limbs, trunk, and intracranial or extracranial sites. Despite their varied presentation across organs and tissues, AVMs can lead to cardiac failures due to high output, necessitating management even in asymptomatic cases.

We present the case of a 37-year-old male with a known history of hypertension and severe depressive disorder, referred to the urology department for bilateral renal calculi evaluation. The patient complained of sudden-onset, moderate-intensity left-sided flank pain, with no signs of infection or constitutional symptoms. A non-contrast CT scan revealed bilateral renal calculi and an intriguing mass in the scroto-inguinal region.

Further investigation through contrast-enhanced computed tomography identified an AVM originating from the right internal iliac artery, located a few millimeters next to the scrotum. A multidisciplinary team, including interventional radiology, urology, and vascular surgery, collaborated to develop a curative strategy. Angioembolization was performed successfully in a single session, involving catheterization and ligation of the feeder vessel using a lipiodol-glue mixture.

Postoperatively, the patient remained stable with mild pyrexia (99°F), a heart rate of 76 bpm, and blood pressure fluctuating between 110-125 mmHg systolic and 72-80 mmHg diastolic. The absence of glue leakage upon saline injection confirmed the effectiveness of embolization. The patient experienced relief from pain and was mobilized on the second postoperative day. This case underscores the importance of a comprehensive approach in managing rare presentations of AVMs, emphasizing successful angioembolization as a viable therapeutic option.
