Eosinophilic granuloma of the cervical spine in a young adult: A rare case report

Background: Spinal eosinophilic granulomas (EG) are rare tumors, mostly reported in the pediatric age group. They constitute <1% of primary bone neoplasms, and cervical spine involvement is uncommon. Case Description: A 20-year-old male presented with neck pain for a 4-month duration. Six years previously, he had received six cycles of vinblastine for biopsy-proven histiocytosis of an axillary lymph node; this resulted in incomplete remission. Present magnetic resonance/computed tomography (CT) imaging revealed a lytic C2 body lesion with atlantoaxial instability. When the CT-guided biopsy was suggestive of EG, he was managed with definitive surgery and adjuvant radiotherapy. Conclusion: Cervical spine EG is rare in adults. CT-guided biopsy should confirm the diagnosis and should be followed by definitive surgery and adjuvant radiotherapy.
