Basioccipital clefts.
Two cases of rare basioccipital clefting are reported. In one patient, 10-year follow-up indicates that the radiologic appearance of the clefts does not change with time. Findings in the other case indicate that additional anomalies may occur in adjacent bone structures developing in sequence. A review of the embryological development and discussion of the radiological findings are presented.
