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