 Motion limits evaluation of detail especially on dedicated IAC sequences. At least 3 new punctate foci of susceptibility are identified (series 1101 images 106, 137, 138), corresponding to cavernous malformations specifically in the deep white matter of the right frontal lobe and left frontal lobe. Overall, numerous previously seen supratentorial and infratentorial cavernous malformations are not significantly changed. There is no evidence of new FLAIR signal, edema, or mass-effect. Likewise there is unchanged dural based left frontal parafalcine enhancing lesion measuring up to 5 mm in width.No evidence of intracranial hemorrhage or acute infarct. Ventricles and basal cisterns are stable in size and configuration. There is no midline shift or herniation. There is persistent opacification of the right maxillary sinus. There is fluid within the mastoid air cells bilaterally.T2 signal within the inner ear structures is not well evaluated. Right internal auditory canal again demonstrates susceptibility effect and is no longer T1 hyperintense. This is favored to represent evolution of chronic blood products in the internal auditory canal. There is no abnormal enhancement appreciated. The cranial nerves within the canal are not well delineated.
1. At least 3 new supratentorial cavernous malformations within the left and right frontal lobes. Numerous supratentorial and infratentorial cavernous malformations are not significantly changed without suggestion of recent hemorrhage.2. T2 signal within the inner ear structures is not well evaluated secondary to artifact. However there is again susceptibility effect within the right internal auditory canal likely representing evolution of chronic blood products.3. Unchanged dural-based left parafalcine extra-axial enhancing lesion that measures up to 5 mm in width, which likely represents a meningioma.
