Surgical Strategy for a Retro-Odontoid Pseudotumor
Retro-odontoid pseudotumors that are not associated with rheumatoid arthritis or hemodialysis are clinically rare. A pseudotumor is a non-neoplastic mass in the retro-odontoid region that can occur in elderly people. Retro-odontoid pseudotumors are regarded as non-neoplastic masses that arise as a result of instability of the atlantoaxial joint. However, Retro-odontoid pseudotumor has occasionally been reported without instability on dynamic radiography.
