The visual acuity of both eyes was normal, while the visual contrast sensitivity of both eyes slightly reduced. Fundus examination showed the swollen and radial superficial hemorrhage of his both optic nerves. Brain MRI scan indicated a huge tumor in the right temporal lobe with clear boundary, close to the skull. The midline structure shifted to the left. Blood tests indicated no hyperlipidemia or lipid disorders. The patient then received tumor resection. The size of the tumor was 5.6 cm × 7.5 cm × 10.1 cm. Histology suggested many foam cell accumulations and the tumor was positive for CD34, CD99, Vimentin, β-Catenin and CD68, but negative for EMA, GFAP, IDH-1, Oliga-2, PR, S-100, and CD1a. Three months after surgery, MRI showed the midline structure was back to normal. The swollen and radial superficial hemorrhage of optic nerves had disappeared. The visual acuity and visual field remained normal.Keywords: intracranial xanthoma, optic nerve, visual function, neurological disorder, optic disc edema |
