Introduction Cerebral cavernous malformations (CCMs) are collections of dilated and irregular capillaries in the brain. Cerebral cavernous malformations are predominantly supratentorial; occipital CCMs are rare. Surgical removal is indicated for CCMs with recurrent hemorrhage, refractory seizures, and expanding lesions. Case Description We describe a case of a 15-year-old male who presented with repeated tonic-clonic seizures and right homonymous hemianopia of 3-week duration. Magnetic resonance imaging (MRI) showed a mass located on the left medial occipital lobe, specifically in the left lingual gyrus. The T2-weighted and T2-gradient echo images confirmed the diagnosis of a CCM. Total microscopic resection was achieved. There were no surgical complications. The visual deficit improved, and the patient was seizure-free on subsequent follow-up visits. Conclusion Surgical resection of an occipital CCM resulted in a remarkable improvement in terms of seizures and visual field deficits.
