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.
报告了7例鼻咽顶钙化病例。这些钙化位于咽囊对面的中线处，4例患者伴有颅颈交界区的神经或骨质缺损。作者估计这种无症状钙化的发生率约为0.1%。这一发现被认为是脊索的钙化残余物。
