Cervical ganglioneuroma as a rare cause of cervicogenic headache: A case report and literature review

Abstract

BACKGROUND: Cervicogenic headache is characterized by chronic posterior neck pain radiating to one side of the head, resulting from cervical spine bone or soft tissue diseases. Cervical ganglioneuroma (GN), a rare benign neuroblastic tumor, especially in the cervical spine, may cause cervicogenic headache-like symptoms. OBJECTIVE: We report a case of GN which was surgically removed successfully to relieve the symptom. CASE REPORT: A 68-year-old male presented with right posterior neck pain with referred pain to the ipsilateral occipital area in May 2020. Despite administration of medications, physical therapy, and spine interventions, the symptoms intermittently recurred over one year. In July 2021, the patient complained of painful limitation of neck motion, especially on right-sided bending; no motor or sensory deficits, except for subjective numbness of the finger tips, were detected. Plain radiography of the cervical spine showed moderate degenerative changes in the mid-cervical spine. Cervical MRI revealed a cystic mass (1.5 cm × 0.5 cm × 1 cm-in size) around the right C2 dorsal root ganglion adjacent to the C1–C2 facet joint. His symptoms significantly improved after complete tumor excision. CONCLUSION: GN of the upper cervical spine should be considered when persistent cervicogenic headache is refractory to conservative management. In such a case, advanced imaging studies such as MRI should be performed for early diagnosis and appropriate treatment.
