Bilateral and Multilevel Vertebral Artery Loop Formation Causing Cervical Radiculopathy: A Case Report and Literature Review.

We present a case of a 60-year-old man with bilateral and multilevel vertebral artery loop formation (VALF) presenting with chronic cervicobrachialgia and dizziness. Magnetic resonance imaging (MRI) revealed bilateral vertebral artery loops at C4-5 compressing the right C5 nerve root, with computed tomography angiography (CTA) identifying an additional loop at the left V1 segment. The patient's symptoms resolved completely with conservative management over a six-month follow-up period. A literature review comparing similar cases over the past two decades reveals successful conservative and surgical management approaches.
