Perineural spread (PNS) of tumor is a recognized pattern of metastasis occurring in the head and neck. Imaging plays a critical role in identifying PNS for adequate staging and treatment planning. Understanding the major branches and pathways of cranial nerves V and VII, key anatomic landmarks, interconnections between these nerves, and pearls and pitfalls of PNS imaging can aid in early detection, appropriate therapy, and the best possible chance for cure.
肿瘤的神经周围扩散(PNS)是头颈部公认的转移模式。影像学在识别PNS以进行充分分期和治疗规划方面起着关键作用。了解颅神经V和VII的主要分支和路径、关键解剖标志、这些神经之间的相互连接以及PNS成像的要点和陷阱,有助于早期发现、适当治疗并提供最佳治愈机会。
