Arachnoid cyst, craniocervical junction, fourth ventricle, intraventricular air, posterior fossa.


Arachnoid cysts are congenital and non-tumorous intra-arachnoid fluid accumulations that make up about 1% of all intracranial space. occupying lesions. We report a patient with a fourth ventricle arachnoid cyst extending to the upper border of the dens of the axis. This patient progressively developed walking difficulty and stiffness in his legs together with difficulty in grasping objects with his hands within one year. The cyst was totally excised and the patient's symptoms improved in the early postoperative period, but he developed intraventricular and intracisternal air which was followed-up conservatively and resolved spontaneously.
