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.
