Introduction

Cerebral cavernous angioma, or cavernoma, is an occult vascular malformation of the central nervous system that frequently develops in the brain parenchyma. It can develop in any age group, but it often occurs between the ages of 30 and 40.[1] According to reports, the annual incidence of cavernous malformations is 0.15–0.56 per 100,000 people, and the annual hemorrhage rate is 0.61–11% per patient-year, which is variable across populations.[2]
Almost 80% of cerebral cavernomas are supratentorial, mainly affecting the subcortical region of the frontal and temporal lobes. Seizures are the most frequent clinical manifestation, mostly associated with hemorrhages but may also be associated with headaches and other focal neurological deficits.[3]
Only 30–50% of lesions are detected by MRI, regardless of whether contrast is administered, leading to an underdiagnosis of the disease. The main imaging method for evaluating and diagnosing cavernomas is MRI, which has a definite advantage over CT in terms of sensitivity.[3]
In this case, we report on a patient who presented with a complex focal seizure disorder associated with small frontal lobe cavernous malformations detected by MRI.
