Ultrasonographic features of mesenteric cysticercosis in a domestic rabbit (Oryctolagus cuniculus).

A 5-year-old, 0.92-kg (2-lb), spayed female Dwarf Hotot rabbit was evaluated for a 1-day duration of lethargy and anorexia. Survey radiographs revealed evidence of gastrointestinal stasis. Abdominal ultrasonography characterized multiple small, round, anechoic structures embedded in the mesentery. These structures were thin walled with hyperechoic strands/septations. Most of the structures contained a well-defined, eccentric, hyperechoic nodule adherent to the intraluminal wall. Mesenteric cysticercosis was confirmed via exploratory laparotomy and histopathology. To the authors' knowledge, this is the first description of the ultrasonographic features of mesenteric cysticercosis in a domestic rabbit.
