Abstract

|
The cavernous malformation is increasingly recognized as a vascular malformation of
the brain that presents with seizures, hemorrhage, or neurologic deficit. We have identified 24
lesions in 12 patients that were diagnosed cavernous malformation of the brain based on the
findings of follow-up magnetic resonance image and surgical biopsy. The location of the
lesions were the supratentorial area in 20 and infratentorial area in 4. Ten lesions were seen
at the periventricular white matter. Combined venous angioma was noted in 4 patients. The
appearance of the lesions classified by signal intensities on MRI was divided into reticular
pattern in 11, punctate pattern in 9, hematoma pattern in 3, and cystic pattern in one. Recent
hemorrhage was identified at 9 lesions that classified into extralesinal type in 4 and
intralesion type in 4. Among 9 hemorrhagic lesions, eight lesions were located at the
periventricular white matter and six lesions showed reticular patterns. We concluded that the
correlation between the eivdence of recent hemorrhage and location and pattern of the lesions
should be evaluated to predict possibility of rebleeding of the cavernous malformation.
