In a study of jugular foramen, it was found that the right jugular foramen was divided into two compartments by the
intrajugular process; the anterior and the posterior part, same as in present study11.In a research on dried skulls and cadavers, osteophytes on the articular surfaces of the median atlanto-axial joint (n = 63), third occipital condyles (n = 3) and the free ossicles (n = 22) were found.12 It was observed in a case of pediatric Bow Hunter's stroke which resulted from a nearly complete occlusion of the vertebral artery of right sidedue to an abnormal spur arising from the right occipital condyle.13 This finding is similar to the present study where a spur originates from right occipital condyle.
