MRI.
Transverse FLAIR (a) shows dilatation of both lateral ventricles and
extensive white matter changes, in which the vascular white matter
lesions coalesce with the periventricular fluid accumulation due to
hydrocephalus. 1mm maximum intensity projection (MIP) of high resolution
T2 weighted sequence (b) illustrates the ‘ballooning’ of the lateral
foramina of Luschka (arrows). Sagittal T2-weighted image (c) shows
dilatation of the fourth ventricle, with a prominent flow artefact over
the cerebral aquaduct (*). Arrow points to a lacune in the pons.
