1·Results: the frontal, nasociliary and lacrimal nerve, divisions of ophthalmic nerve, entered the orbit via the superior orbital fissure.

结果：眼神经的分支额神经、鼻睫神经和泪腺神经均经眶上裂入眶。

2·There are communicating branches among the temporal branches, the zygomatic branches and the supraorbital and lacrimal nerves of the ophthalmic nerve.

两支之间以及与眼神经的眶上神经和泪腺神经之间，都有交通支。

3·Lacrimal gland enlargement may be seen. CT and MRI may also show stretching and apical crowding of the optic nerve with an enlarged superior ophthalmic vein.

泪腺增大也可以出现，CT和MRI可能表现为“拉胀”，视神经尖端拥挤，眼上静脉扩张。

4·Shape and margin: Most tumors had an irregular shape with obscure margin, infiltrating around the structures of the eyeball, lacrimal gland, extraocular muscle, optic nerve and (or) bone.

形态边缘：肿瘤形态多不规则，边缘呈浸润状，沿眼球壁、泪腺、视神经、眼外肌、眶隔或眶壁蔓延生长。
