影像表现】:Figure 1, Figure 2, and Figure 3: Contrast enhanced axial CT images through the neck demonstrate a 4.5 X 6 cm circumscribed and moderately enhancing mass within the right carotid space with scattered areas of low density centrally within the mass (blue arrows). The internal and external carotid arteries (green arrows) as well as the parapharyngeal fat (red arrow) are displaced anteriorly. The parotid gland is separate from the lesion (purple arrow).TpU影像园XCTMR.com

Axial and coronal T2 weighted images (Figure 4 and Figure 5) and axial and coronal T1 weighted post-gadolinium fat saturated images (Figure 6 and Figure 7) again show a well defined mass with heterogeneous T2 signal and areas of cystic degeneration (blue arrows). There is peripheral enhancement following gadolinium administration (orange arrows). Note that the mass is not contiguous with the parotid gland (purple arrows).TpU影像园XCTMR.com

【诊断要点】:Vagal schwannomas are benign tumors that may present with hoarseness or cough, however the majority of patients are asymptomatic. 迷走神经鞘瘤是一种良性肿瘤,可以表现为声音嘶哑或咳嗽,然而大部分病人没有症状。TpU影像园XCTMR.com

    Schwannomas of the vagus nerve need to be differentiated from paragangliomas because the distinction may influence treatment planning 迷走神经鞘瘤需要与副神经节瘤相鉴别,其差异可能影响治疗计划。
