To describe the elongated anterior tubercle of cervical vertebrae, its association with incomplete segmentation, and its analogy to sacralization of the lower lumbar vertebrae.
Cases with elongated anterior tubercles of the cervical vertebrae detected on plain radiography were collected during routine practice and their features analyzed on plain radiography and MR imaging. Five patients, aged 19-40 years, with the anomaly seen on plain radiography were included in this study. MR imaging was undertaken in one patient.
Hypertrophy of the anterior tubercle was associated with incomplete segmentation in three of the five patients. Oblique views were adequate to demonstrate its nature.
The association of an elongated tubercle and incomplete segmentation is similar to partial sacralization at the lumbosacral junction. Clinically it is important that these anomalies are not mistaken for pathologic findings.
描述颈椎延长的前结节、其与椎体节段未完全融合的关系，以及其与下腰椎骶化的相似性。
在常规检查中收集经X线平片检测出颈椎前结节延长的病例，并对其X线平片和磁共振成像（MR成像）特征进行分析。本研究纳入了5例年龄在19至40岁之间、X线平片显示有该异常的患者。其中1例患者接受了MR成像检查。
5例患者中有3例的前结节肥大与椎体节段未完全融合有关。斜位片足以显示其特征。
延长的结节与椎体节段未完全融合的关系类似于腰骶交界处的部分骶化。临床上，重要的是不要将这些异常误诊为病理表现。
