Seven cases of calcification in the roof of the nasopharynx are reported. These calcifications situated in the midline opposite the pharyngeal bursa, were associated in four patients with a neural or osseous defect of the craniocervical junction. The authors estimate the frequency of this asymptomatic calcification to be about 0.1%. This finding is thought to be a calcified remnant of the notochord.
