Abstract

We report the clinical significance of anterior cerebral artery (ACA) notching on the optic nerve and chiasm in a 3.5-year-old girl with a craniopharyngioma and progressive blindness. She presented with a headache and vomiting, followed by binocular blindness. Magnetic resonance imaging (MRI) studies demonstrated severely distended A1 segments and ill-depicted ACAs. Surgical decompression via a right subfrontal approach was performed to reverse blindness. Postoperative MRI studies showed good ACA visualization. A second operation via a right pterional approach revealed ACA notching, which appeared as a transverse groove on the right optic nerve and chiasm. ACA notching should be considered as a possible cause of progressive visual disturbance and a potential risk of ACA infarction in a child with a craniopharyngioma.
