在一些骨骼发育不良和综合征中已有枕骨投射的报道。我们观察到两例有枕骨投射的I型寰椎成骨。这一发现既没有在任何形式的寰椎成骨中被注意到，也没有报道。这导致我们在国际骨骼发育不良登记处搜索枕骨投影，我们在其他四个没有报道的综合征中发现了枕骨投影。因此，枕骨刺是一种非诊断性特征，至少可以在十种不同的疾病以及正常的变异中找到。
Occipital projections of the cranium have been reported in a number of skeletal dysplasias and syndromes. We observed two cases of atelosteogenesis type I with a bony occipital projection. This finding has neither been noted nor reported in any form of atelosteogenesis. This led us to search the International Skeletal Dysplasia Registry for occipital projections, and we found them in four other syndromes in which they had not been reported. Thus occipital spurs are a non-diagnostic feature that can be found in at least ten distinct disorders as well as a normal variant.
