Living-related donor kidney transplant complicated by PTLD (DLBCL - type) involving the CNS, LN and gut. There is unchanged extensive diffuse cerebral white matter T2 hyperintensity. There are also unchanged punctate foci of susceptibility effect in the bilateral frontal lobes. There is also an unchanged focus of susceptibility effect in the medial right cerebellar hemisphere with mild peripheral enhancement and diffuse confluent T2 hyperintensity. There is a milder degree of T2 hyperintensity in the left cerebellar hemisphere. There is no evidence of acute infarct. The ventricles and sulci are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is mild scattered paranasal sinus mucosal thickening. There is a small amount of fluid within the bilateral mastoid air cells. There are bilateral lens implants. There is unchanged diffuse T1 hyperintensity of the clivus and imaged portions of the cervical spine, likely related to radiation therapy.
Unchanged extensive diffuse cerebral white matter T2 hyperintensity likely related to treatment effects and unchanged treated right cerebellar lesion. No evidence of new intracranial lesions.
