Abstract
We report a case of an incidental nodular calcification of the alar ligament simulating a fracture in the craniovertebral junction of a previously healthy 24-year-old man. Three-dimensional CT and MR imaging revealed a 7.2 x 7.6 x 4.0 mm nodular calcification in the right alar ligament with normal adjacent bony structures. Serial cervical dynamic radiographs and open-mouth views showed that the cervical spine was stable without any change in the calcification.
摘要
我们报告一例偶然发现的翼状韧带结节状钙化病例，该病例模拟了一名既往健康的24岁男性颅颈交界处的骨折。三维CT和磁共振成像显示右侧翼状韧带存在一个7.2×7.6×4.0毫米的结节状钙化，相邻骨质结构正常。连续的颈椎动态X线片和张口位片显示颈椎稳定，钙化无任何变化。
