5y F Persian imaged for ureteral obstruction. Images are ordered from cranial to caudal. The uterus is markedly enlarged and fluid filled
with enhancing walls (a–c: arrows). Folds are visible in the wall of the uterus, causing an undulating pattern. The ovaries were unremark­
able (not shown). An ovariohysterectomy was performed, and marked endometrial hyperplasia and endometritis were found on histopa­
thology, possibly related to recent pregnancy.

1y M Shih Tzu imaged for an extrahepatic portosystemic shunt. Images a and b are ordered from caudal to cranial. The right testicle
is mildly atrophied (a: solid arrow) and is located in the inguinal region external to the body wall (a: open arrow). The epididymis is
visible laterally as a more strongly enhancing curvilinear structure (a: arrowhead). The left testicle (b: solid arrow) is located internal
to the abdominal wall (b: open arrow) and lateral to the bladder (b: asterisk). There is minimal contrast enhancement, and the
epididymis is not visualized. On the dorsal plane image, the testicles (c: arrows) are internal to (left) and external to (right) the
musculature of the body wall (c: open arrows).
