This is a classical picture of what we call isolated ventricles... There is no shunt blockage...The right ventricle where the shunt is seen is not dilated..The left ventricle is grossly dilated..This is due to interventricular blockage which happens in adhesive ventriculitis as in this case..This can also happen in TBM, postoperative cases etc.. i put an additional shunt in left ventricle here.

Left lateral venticle is dialated. Partial collapse of rt lateral ventricle with beading appearance. TIP of shunt tube is in the body of lateral ventricle with hyperdensity left posterior horn of rt lateral ventricle and also hyperdensity near rt parietal area near the site of shunt insertion. Multiple hyperdensity along the shunt tube -Is it broken shunt tube ?
