Abstract
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.
