We report a case of a 11-year-old boy who presented with sudden loss of visionÂ in the right eye. Two days before he experienced a mild headache when he wokeÂ up that vanished during the day. A cerebral computed tomography scan (CT) andÂ an magnetic resonance imaging (MRI) revealed a lesion in projection to the rightÂ suprasellar cistern. At the operation a typical cavernous malformation (CM) withÂ old and fresh hematoma was found in the right optic nerve (ON), optic chiasm (OC)Â and optic tract (OT) with a surrounding hemorrhage. Microsurgical total resectionÂ was done and the patientâ€™s vision much improved. This case report emphases theÂ importance of a rapid diagnosis and reminds us that CM can also occur in youngÂ patients presenting as an unilateral sudden loss of vision.
