Re-evaluate left skull base lesion. There is no interval change in the enhancing lesion centered in the left clivus. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is unchanged mild nonspecific cerebral white matter T2 hyperintensity. There is no abnormal intracranial 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, paranasal sinuses, and scalp soft tissues are unchanged.
Unchanged left central skull base lesion, which may represent a form of fibroosseous dysplasia versus an indolent neoplastic process perhaps.
