Abstract
This study explores the manifestation of retro-odontoid pseudotumor associated with rheumatoid arthritis (RA) pannus, emphasizing its impact on craniocervical instability. The condition involves non-neoplastic tissue proliferation near the odontoid process, potentially leading to medullary compression and severe neurological complications. The study presents a clinical case involving a 72-year-old female patient with RA, demonstrating the efficacy of transoral microsurgical resection for anterior decompression and subsequent occipitocervical fixation. The case highlights the importance of immediate medullary decompression, resolution of etiological instability, and histopathological analysis for definitive diagnosis in managing retro-odontoid pseudotumor associated with RA pannus. The findings suggest that traditional fixation methods, particularly cage stand-alone, may be insufficient for achieving the required cervical stability in RA patients, raising important considerations for therapeutic interventipns.
