Figure 2.1.7 Obstructive Hydrocephalus (Canine) MR
5y MC Labrador Retriever with hydrocepha-
lus affecting the left lateral ventricle. A small
contrast‐enhancing mass is present on the
ventral margin of the left lateral ventricle
(a,d: arrowhead). The left lateral ventricle is
markedly distended, and there is a thin rim of
hyperintensity, best seen on the FLAIR image
(b: arrows), thought to represent transepend-
ymal interstitial edema. A choroid plexus
carcinoma involving the floor of the left
lateral ventricle and causing partial foraminal
obstruction was confirmed on postmortem
examination.
