Severe right sided headache with visual symptoms. CT and MRI were done, which showed a right parietal cavernoma. There is a lesion with extensive susceptibility effect in the superior portion of the right postcentral gyrus that measures up to 8 mm. There is an associated small developmental venous anomaly, but no surrounding vasogenic edema. There is no evidence of intracranial hemorrhage or acute infarct. There are a few scattered foci of nonspecific cerebral white matter T2 hyperintensity without susceptibility effect or enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Findings compatible with a right parietal lobe cavernous malformation.
