The jugular tubercles are two small protuberances that arise from the inferolateral margins of the clivus and project posterosuperiorly over the hypoglossal canals. The jugular tubercles are clearly seen on routine anteroposterior temporal bone tomograms and may be identified on axial or coronat CT scans. Varying widely in size and configuration, these structures are usually somewhat ovoid but can be elongated, gently squared, or asymmetric. Despite this variation in size and appearance, no normal instances were found in which the superior surface of the jugular tubercles appeared either flattened or concave. The radiology of the normal and pathologic jugular tubercle is described. The material outlined was derived from radiographic studies of both dried skulls and a variety of normal and abnormal clinical cases.
颈静脉结节是两个小的突起，从斜坡的下外侧边缘发出，并在舌下神经管上方后上方向突出。在常规颞骨前后位体层摄影片上可清晰看到颈静脉结节，在轴向或冠状CT扫描上也可识别。这些结构的大小和形态差异很大，通常 somewhat 呈椭圆形，但也可能拉长、略呈方形或不对称。尽管大小和外观存在这种差异，但未发现颈静脉结节上表面呈扁平或凹陷的正常情况。本文描述了正常和病理性颈静脉结节的放射学表现。所述材料来自对干燥颅骨以及各种正常和异常临床病例的影像学研究。
