Although C1–C3 upper cervical radiculopathy can cause a headache, most case reports are occipital neuralgia (ON), not headache. Here, we report a unique case of chronic temporo-occipital headache due to C3 radiculopathy. A 62-year-old male presented with a chronic left-sided temporo-occipital headache with duration of 4 years. The headache was aching and pressure like in nature. It had a typical radiating pattern on every occasion. It started in the posterior temporal area above the ear. It then extended to retroauricular area, then suboccipital area, and lateral neck. No hypesthesia, allodynia, or limitation in neck motion was noted. Myelographic computed tomography revealed a left-sided C2/C3 foraminal stenosis. Subsequent foraminotomy and decompression of the left C3 completely alleviated the chronic left-sided temporo-occipital headache. Unilateral C3 radiculopathy can cause chronic temporo-occipital headache besides ON. The present case might be a typical example of “headache attributed to upper cervical radiculopathy” (A11.2.4) rather than cervicogenic headache according to the International Classification of Headache Disorders, 3rd edition (beta version).
Key-words:
C3 radiculopathy - greater occipital nerve - headache - lesser occipital nerve - occipital neuralgia
