•Cavernous malformation should be a differential diagnosis of suprasellar lesions.•Management of asymptomatic optic apparatus cavernous malformation is still debatable.•The relative risk of visual deterioration after repetitive hemorrhage may be higher than the risk of surgical removal. A 62-year-old woman presented with a history of headaches for two weeks and sudden loss of vision in her left eye. Neurological examination revealed right eye acuity 6/6, left eye 6/9.5, left eye relative afferent pupillary defect (RAPD), red desaturation reduced in the same eye, confrontation visual fields showed non-congruent right homonymous hemianopia. Fundoscopy did not show any sign of papilledema or chronic optic atrophy (Fig. 1). There was no other focal neurological deficit [1Tan T. Tee J.W. Trost N. McKelvie P. Wang Y.Y.
