Figure 1 Preoperative MRI of the tumor in right parapharyngeal space
(A) 右侧咽旁间隙肿物冠状切面图,可见椭圆形T1W低信号,边缘光滑清晰,大小约3.0 cm ×1.8 cm ×4.8 cm,增强呈不均匀强化(蓝色箭头);(B) 右侧咽旁间隙肿物水平切面,T2W混杂高信号(蓝色箭头)。
(A) The coronal section of the tumor in the right parapharyngeal space showed oval T1W low signal, smooth and clear edge with approximately 3.0 cm ×1.8 cm ×4.8 cm in size, and uneven enhancement (blue arrow); (B) The horizontal section of the tumor demonstrated T2W mixed high signal (blue arrow).

Figure 2 Appearance of the eye on the first day after operation
(A) Upper blepharoptosis in right eye (upper eyelid covering 4 mm of upper limbus of cornea) and the left eye appeared normal; (B) Pupil diameter of right eye decreased significantly (the diameter of right pupil was about 1.5 mm and left pupil was about 2.5 mm).

Figure 3 Postoperative pathological examination of the tumor in right parapharyngeal space
(A) Pathological findings suggested reactive hyperplasia of right cervical lymph nodes lymph node (HE, ×40; irregular arrangement of lymphatic follicles and proliferative T cells); (B) T??he right skull base tumor: It was conformed as schwannoma (HE, ×100); a large number of spindle cells could be seen in the field, the cytoplasm was red and partly bright, arranged in bundles and vortexes.
Central: hypothalamus - midbrain - pons - medulla oblongata - lateral angle of C8-T2 (the ciliary center itself is excluded); Preganglionic: ciliary center - below subclavian artery - crossing apex of lung - common carotid artery - inferior cervical ganglion - middle cervical ganglion - superior cervical ganglion (the superior cervical ganglion is excluded); Postganglionic: superior cervical ganglion is divided into two ways: one with external carotid artery (dominating facial sweating and vasoconstrictive fibers), the other way (internal carotid artery-cavernous sinus-superior orbital fissure-eye).
