NK/T-Cell Lymphoma s/p MUD PBSCT with CNS PTLD. There has been interval evolution of post-biopsy findings in the right precuneus region. There is interval decrease in size of the mass with diffuse intrinsic T1 hyperintensity and susceptibility and minimal patchy enhancement. The lesion now measures up to 28 mm in width, previously 36 mm. There is also decrease in the extent of the surrounding confluent white matter T2 hyperintensity. There is slightly decreased effacement of the trigone of the right lateral ventricle. There is no midline shift or herniation. There is persistent pansinus inflammation and secretions.
1. Interval decrease in size of the biopsied right parietal lobe PTLD lesion and associated edema.2. Persistent pansinusitis.
