 There are postoperative findings related to right parietal craniotomy for resection of a right frontal lobe mass. There is mildly decreased diffusion along the resection margins and prominent susceptibility effect in and adjacent to the resection cavity compatible with blood products. There is residual enhancement along the resection margins most compatible with residual tumor. There is confluent T2 hyperintensity surrounding the resection cavity and extending into the deep white matter of the right frontal lobe that demonstrates questionable mildly elevated relative cerebral blood volume. There is additional elevated relative cerebral blood volume throughout the medial right cerebral hemisphere including within the corpus callosum of uncertain significance. There multiple punctate foci of T2 hyperintensity throughout the supratentorial white matter which are most compatible with chronic small vessel ischemic disease. 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. There are bilateral lens implants.
Postoperative findings related to recent craniotomy with residual enhancing tumor adjacent to and surrounding the resection cavity.
