Abdominal Ultrasound. Initial presentation ultrasound:hypoechoic intraluminal fluid of the small intestine in the right caudal ventral abdomen. Screen depth = 21 cm (a). Initial presentation ultrasound:mildly dilated loops of small intestines with hypomotility. Screen depth = 25 cm (b). Day 3 of hospitalization ultrasound:dilated small intestines (range: 4-8 cm in diameter) of the right lateral abdomen, thickening of small intestinal wall. Screen depth = 18 cm (c). Day 6 of hospitalization ultrasound:normal small intestinal luminal diameter (4-5 cm in diameter) with regular peristaltic intervals observed, no luminal distention of small intestine observed. Screen depth = 21 cm (d).

Ultrasound of the right caudal ventral abdomen was conducted with a 2-5 MHz curvilinear probe (SonoSite Edge II Ultrasound System, Fujifilm) and revealed hypoechoic intraluminal fluid with loops of intestines that were mildly distended with hypomotile appearance (Figures 1(a) and 1(b)). Abdominal ultrasound revealed dilated intestines (4-8 cm) with echoic material consistent with fibrin occasionally seen inside the lumen (Figure 1(c)). A repeat abdominal ultrasound revealed frequent peristalsis, without any signs of distention (Figure 1(d)).
