title: Cervical radiculopathy caused by vertebral artery loop formation: multislice computed tomography angiography findings.
abstract: Vertebral artery tortuosity and loop formation are rare causes of cervical radiculopathy. The criterion standard for the detection of vertebral artery loop formation is digital subtraction angiography. Computed tomography (CT) and magnetic resonance imaging provide good accuracy in the evaluation of vertebral arteries. A case of vertebral artery loop formation is reported. The diagnosis was confirmed by 16-row multisection CT angiography findings of vertebral artery loop formation.
