Migraine headaches. History of congenital cavernous malformation. Redemonstration of a very small focus of susceptibility artifact within the mesial right precentral gyrus seen primarily on the gradient echo images compatible with a small congenital cavernous malformation. There is perhaps subtle associated T2 signal abnormality associated with lesion, but no significant perilesional vasogenic edema. There is no associated enhancement. No additional lesions are identified.The T2, FLAIR and diffusion weighted images are otherwise normal.There is no evidence of intracranial hemorrhage, mass or edemaThe ventricles and basal cisterns are normal in size and configuration.The expected intracranial vascular flow voids are present.The paranasal sinuses are clear. The visualized mastoid air cells are clear. The orbits are unremarkable.
Stable findings compatible with a small suspected cavernous malformation in the mesial aspect of the right precentral gyrus. No additional lesions are identified.
