Presentation
Known migraine. Worsening vertigo sustained a fall. IC bleeding?
Patient Data
Subtle decrease of the density of the right cerebellar white matter, but no loss of cortical differentiation. No evidence of trauma (not all reconstructions shown).
Due to ongoing vertigo and nystagmus, posterior circulation stroke was suspected. Focused MRI performed a day later.
Marked right cerebellar wedge-shaped, matched T2 and FLAIR hyperintensity with associated DWI/ADC diffusion restriction in line with superior cerebellar arterial infarct. Note that the vermis and pons are spared.
Case Discussion
Typical imaging findings in an acute-subacute superior cerebellar artery territorial infarct.
