 There is redemonstration of a large bilobed heterogeneously enhancing lesion centered in the right caudate head and anterior basal ganglia region, that measures 3.4 x 2.4 cm in greatest axial dimensions, compared to previous 3.3 x 2.5 cm, respectively. Please note that remeasurement were obtained, as one of the previous measurements was obtained through the narrow waist of the bilobed lesion, resulting in under measurement. T2 signal remains heterogeneous, with a peripheral T2 hypointense rim of hemosiderin. Small air-fluid levels are again seen, with prominent blooming artifact on susceptibility. A tiny exophytic lobular component of the mass extends just beyond the midline with slight mass effect on the anterior aspect of the third ventricle. There is also mild localized mass effect on the right frontal horn. There appear margin the lesion abuts the right A1 segment. There is no surrounding FLAIR hyperintensity to suggest recent hemorrhage.The ventricles and sulci are otherwise within normal limits. The cisterns remain patent. There is no midline shift. Other scattered punctate foci of T2/FLAIR hyperintensity are seen within the cerebral white matter bilaterally which are nonspecific. No new foci of susceptibility are appreciated. 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.
1. Redemonstration of right caudate/basal ganglia cavernoma without significant interval change in size or overall configuration. No evidence of surrounding FLAIR abnormality to suggest recent hemorrhage.2. Stable appearance of minimal scattered punctate foci of nonenhancing T2/FLAIR hyperintensity within the cerebral white matter bilaterally, which are nonspecific.
