METHODS We retrospectively reviewed the records of 253 patients, ages 1 to 77 years old, who had had thin-section CT examination of the skull base.

RESULTS An ossification center appeared midline in the patients who were 8 to 13 years old. Six of 12 girls showed additional symmetric ossification centers on either side of the midline; however, this pattern was not seen in boys. No sphenooccipital synchondrosis persisted in any patient past the age of 13 years.

CONCLUSION High-resolution CT scans of the skull base can show a pattern of progressive ossification of the sphenooccipital synchondrosis, which can be readily recognized and predicted." />
