Perineural spread is a common growth pattern of head and neck malignancies. Recognizing this pattern by imaging is important for two reasons: 1) it may be the only evidence of malignancy; and 2) its presence in conjunction with a mass converts management from surgical resection to radiation or chemotherapy. High field strength magnets and thin sections with high resolution and fat suppression now allow earlier diagnosis of this entity, but even with these imaging developments, familiarity with the relevant anatomy and the subtle alterations on MRI are necessary to identify this condition.
神经周围扩散是头颈部恶性肿瘤常见的生长模式。通过影像学识别这种模式很重要，原因有两点：1）它可能是恶性肿瘤的唯一证据；2）其与肿块同时存在会使治疗方案从手术切除转变为放疗或化疗。高场强磁体以及具有高分辨率和脂肪抑制的薄层扫描现在能够更早地诊断这种情况，但即便有了这些影像学进展，熟悉相关解剖结构以及MRI上的细微改变对于识别这种病症仍是必要的。
