Figure 2

Tractography study. 3D projection of brainstem tractography (posterior view) at 1.5 T in patient 1 (A), patient 3 (B) and a normal control (C) with 16, 12 and 30 non-collinear diffusion-encoding directions, respectively. In both patients (A, B) the red streamlines of the pontine tegmentum "cap" are clearly visible (arrowhead): some of them continue into the expected location of the middle cerebellar peduncles, possibly representing fibres projecting to the cerebellum. In the normal subject (C), red streamlines (arrowhead) represent the more anteriorly located pontine trasverse fibers, partially "covered" by fibers running longitudinally in the brainstem tegmentum.
