BACKGROUND AND IMPORTANCE: If ophthalmic artery's (OphA) origin anomalies are frequent, the superolateral origin of the OphA was rarely described. CLINICAL PRESENTATION: During an aneurysmal surgery, a superolateral origin of the left OphA was found. This variation was associated with a sylvian aneurysm. The anatomical, embryological features, the neurosurgical implications of this origin such as treatment of carotid-ophthalmic aneurysm or intra arterial retinoblastoma chemotherapy are discussed. CONCLUSION: To the best of our knowledge, this is a very rare operative case of both superolateral origin and initial course of OphA.
