Review Case Reports
Modified posterior atlantoaxial screw-rod fixation in a case of persistent first intersegmental artery. Case report and literature review.
This case reports atlantoaxial stabilization in case of V3 segment anomaly. ⋯ This rare vascular anomaly described in 2 to 5% of the patients led us to modify the screw entrance over the C1 posterior arch in order to obtain a satisfactory stabilization and to limit the risk of vertebral artery injury.

Review Case Reports
[Epidermoid cyst of the cisterna magna and the fourth ventricle: Report of four cases].
Epidermoid cyst is a congenital and benign tumor, developed from ectodermal inclusion. These cysts occur very rarely in the cisterna magna and the fourth ventricle. ⋯ Epidermoid cysts are characterized by a long evolution. The diagnosis is relatively characteristic in the imagery. The prognosis was favourable with a complete surgical resection.
