The posterior fossa is difficult to evaluate on CT because of poor contrast resolution and artifacts. MRI more clearly demonstrates the anatomy and pathology of the middle cerebellar peduncle in the posterior fossa than does CT. FLAIR images occasionally show a slight increase in signal intensity in normal middle cerebellar peduncles (Figure 1F).

By thirteen years of age, when he had worsening dysarthria and falls, MRI demonstrated bilateral calcifications and cysts, some with contrast enhancement, in the periventricular regions, basal ganglia and thalami, and increased T2/FLAIR (fluid-attenuated inversion recovery) signal changes in periventricular and subventricular white matter.

3D T1-weighted, axial T2-weighted, axial fluid attenuated inversion recovery (FLAIR), and gradient echo sequences were acquired using an 8-channel phased array head coil. BOLD scanning was performed to assess CVR (see below) at 4mm isotropic resolution, with whole brain volume acquired every three seconds using the parameters published previously.1

A, B and C: Brain MRI showed intense T2 Flair, T1 and DWI signal changes in the left basal ganglia (circle). D and E: Brain MRI showed intense T2 Flair signal changes in the left hippocampus and temporal lobe (asterisk), and right frontoparietal lobe (arrow), respectively. F: CUBE technique found no sign of meningitis.
