A 23-year-old woman presented with subacute monocular visual loss clinically resembling optic neuritis. CT scan revealed a cerebellar mass, biopsy of which led to the diagnosis of reticulum cell sarcoma (RCS). Corticosteroid therapy resulted in improvement of vision and a decrease in disc edema; this resolution was documented radiographically. While optic nerve involvement is sometimes seen in association with systemic lymphoproliferative disease, optic neuropathy as a manifestation of primary cerebral RCS is rare.
一名23岁女性出现亚急性单眼视力丧失，临床症状类似视神经炎。CT扫描显示小脑有一肿块，对其进行活检后诊断为网状细胞肉瘤（RCS）。皮质类固醇治疗使视力得到改善，视盘水肿减轻；影像学检查记录了这种好转情况。虽然视神经受累有时与全身性淋巴增殖性疾病相关，但原发性脑RCS表现为视神经病变的情况较为罕见。
