44 years, Male, progression of lesion. Compared to multiple prior studies, there is evidence of gradual decrease in foci of intraparenchymal hemorrhage which involve the right mid callosal body and extend superiorly to the posterior aspect of the right superior frontal gyrus. There is also interval decrease in previous seen associated T2/FLAIR hyperintensity involving the adjacent periventricular and subcortical white matter related to edema. There is no abnormal enhancement or abnormal flow-voids to suggest an underlying lesion.Remainder of the brain demonstrates no intracranial mass or mass effect. No abnormal parenchymal or meningeal enhancement. No evidence of recent ischemia or new hemorrhage. There is a tiny nonspecific focus of T2/FLAIR hyperintensity involving the left inferior frontal white matter. No hydrocephalus. No extra-axial collections. Major flow-voids are preserved. Tiny left maxillary sinus mucus retention cyst. Calvarium and extracranial soft tissues are grossly unremarkable.
Compared to multiple prior studies, there is evidence of gradual decrease in blood products involving the right mid callosal body and extending superiorly to the posterior aspect of the right superior frontal gyrus. Current study demonstrates essentially resolution of the prior findings with residual signal abnormality compatible with hemosiderin staining and gliosis. No underlying enhancing mass or abnormal flow-voids are appreciated to suggest an underlying lesion. Remainder of the brain is unremarkable.
