A cervical disc herniation can contribute to nerve-root irritation, but imaging findings must be correlated with the clinical pattern.
Radicular symptoms may include arm pain, sensory change, weakness or reflex change in a root-related distribution.
Disc appearance alone does not establish symptomatic cervical radiculopathy; examination and red-flag screening remain essential.
The visual should be interpreted with the accompanying clinical context. PNA avoids using a single image or special test as stand-alone proof of a diagnosis.
