The purpose of this original report is to describe medial transposition of the common carotid arteries. This transposition may produce wide retropharyngeal soft tissues on lateral cervical radiographs.
When common carotid arteries are transposed from their normal lateral positions into the retropharyngeal soft tissues, if vascular calcifications are present, this carotid abnormality is easily recognized on plain radiographs. Radiologists and clinical physicians should be aware that vascular transposition may be a benign cause of widening of the retropharyngeal soft tissues.
本原始报告的目的是描述颈总动脉的内侧移位。这种移位可能会在颈椎侧位片上产生广泛的咽后软组织增宽。
当颈总动脉从其正常的外侧位置移位至咽后软组织时，如果存在血管钙化，这种颈动脉异常在平片上很容易识别。放射科医生和临床医生应意识到血管移位可能是咽后软组织增宽的一个良性原因。
