Heart replaced by transplant [V42.1], Reason for Study: ^Reason: 65yo F w/ hx of CNS nocardia. Monitor for interval progression. History: CNS nocardia Redemonstration of well marginated enhancing mass of the corpus callosum splenium with surrounding edema extend toward bilateral trigone areas and occipital lobes. The size of the mass was measured about 24.2mm x 17.6mm x 18.6mm. Considering slightly different scanning plane and measurement errors, there is no significant interval change of the mass in terms of size and MR characteristics.Right posterior pontine susceptibility lesion, no change since prior scan.No change of non specific small vessel ischemic disease since prior scan.No change of multiple susceptibility lesions on bilateral hemispheres suggesting chronic micro-hemorrhages, since prior scan.No change of empty sellar.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Corpus callosum splenium mass, no change since prior exam in terms of size and MR characteristics.No change of right posterior pontine susceptibility artifacts, multiple bihemispheric susceptibility artifacts and non specific small vessel ischemic disease since prior scan.No evidence of new acute ischemic or hemorrhagic lesion.
