Reason: history of T-cell leukemia and LCH s/p radiation therapy and stem cell transplant History: monitor for meningioma s/p radiation therapy Areas of previous punctate irregular T1 and T2 hyperintensity within the caudate head and putamen bilaterally are again noted, although overall appear slightly less conspicuous than on prior exam. There is again subtle if any susceptibility associated with these areas of abnormality. There is no convincing superimposed enhancement. Additional punctate focus of susceptibility along the right parietal periatrial white matter is unchanged.The ventricles and sulci are stable, with mild global volume loss. The cisterns remain patent. There is no midline shift or mass effect. There is no diffusion abnormality. No extra-axial fluid collection is identified. Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. There is mild mucosal thickening throughout the paranasal sinuses. This includes a few lobulated areas that appear posterior to the left frontal sinus, which are actually areas of pneumatization contiguous with the sinus lumen when correlating with previous available CT images from PET/CT.
1.No evidence of intracranial mass.2.Stable nonspecific nonenhancing foci of abnormal signal along the putamen and caudate bilaterally.
