Perineural tumor spread (PNS) substantially alters a patient's prognosis and treatment plan. Therefore, it is critical that the radiologists are familiar with the course of cranial nerves commonly affected by PNS and the neuronal connections to appropriately map the extent of PNS. Limited involvement of a nerve by PNS might be resectable, whereas advanced PNS may require radiation therapy.
神经周围肿瘤扩散（PNS）会显著改变患者的预后和治疗方案。因此，放射科医生熟悉PNS常见累及的颅神经走行以及神经连接，从而准确描绘PNS的范围至关重要。PNS对神经的轻度累及可能可切除，而进展期PNS可能需要放疗。
