Neurofibroma is also a benign tumor of the peripheral nerve. It is different from neurotheca in that in addition to the proliferation of nerve sheath cells, the pathological tissue is also mixed with the proliferation of intraneural fibroblasts. The clinical manifestations are also more diverse than those of neurotheca. According to symptoms, signs and pathological histological changes, orbital neurofibromas can be divided into four types: solitary or localized, plexiform, diffuse and post-resection neuroma. Orbital neurofibromas [1] are divided into the first three types, which can appear alone in the orbit, but can also be part of neurofibromatosis. The latter type represents a large amount of overgrowth of peripheral nerves after resection, but it is extremely rare in the orbit. Orbital plexiform neurofibroma combined with neurofibromatosis
