Perineural tumor spread (PNS) is a well-recognized entity in head and neck cancers and represents a mode of metastasis along nerves. The trigeminal and facial nerves are most affected by PNS, and their connections are reviewed. MRI is the most sensitive modality for detecting PNS, and their anatomy and interconnections are reviewed. MRI is the most sensitive modality for detecting PNS, and imaging features of PNS and important imaging checkpoints are reviewed. Optimal imaging protocol and techniques are summarized as well as other entities that can mimic PNS.
神经周围肿瘤播散（PNS）是头颈部癌症中一种公认的现象，代表着一种沿着神经转移的方式。三叉神经和面神经最容易受到 PNS 的影响，本文回顾了它们的连接。MRI 是检测 PNS 最敏感的方式，本文回顾了其解剖结构和相互连接。MRI 是检测 PNS 最敏感的方式，本文回顾了 PNS 的影像学特征和重要的影像学检查点。本文还总结了最佳的成像方案和技术以及其他可能模拟 PNS 的实体。
