      A 44-year-old woman with Castleman disease presented with acute visual loss in the left eye. A full ophthalmologic
      examination and imaging were performed. Visual acuity was 20/20 in the right eye and 20/100 in the left eye. Total
      dyschromatopsia, a relative afferent pupillary defect, and a cecocentral scotoma were observed in the left eye. Mild
      disc edema, without leaking during fluorescein angiography, was also observed. Magnetic resonance imaging re-
      vealed a small cystic epidermoid-like lesion in the right prepontine and suprasellar cistern. Her visual acuity did not
      improve and deteriorated to 20/200 in the left eye at 22 months after the initial visual loss. Optic neuropathy may
      rarely be associated with Castleman disease and suggests a poor prognosis.
