Findings
was changed:
The patient refused surgery. An MRI exam was performed one year later (follow-up for same symptoms) showing:
- the same extra-axial lesion in the left cerebellopontine angle mass in keeping with a meningioma
. - multiple lesions of various sizes along the surface of the cerebellar and cerebral hemispheres which were not visible on the MRI exam performed one year ago. they display an iso-to low signal to the cortical grey matter on T1WI, slight high signal on T2WI/FLAIR with heterogeneous enhancement on postcontrast sequences suggestive of cerebral metastases
. The; the largest lesions are located in the right frontal and left parietal regions with surrounding oedema, - On axial GE there are numerous corticosubcortical (grey-white matter junction) low signal blooming artifact, sparing the basal ganglia, pons and cerebellar hemispheres, more consistent with cerebral amyloid angiopathy (not detected on the previous MRI exam because theT2* sequences: GRE, echo-planar, SWI were not performed)
