A canine case of partial heterotaxia detected by radiography and ultrasound

With radiography and ultrasound, reversed positioning of the fundus ventriculi and pylorus, a duodenum running on the left side, transposition of the kidneys, and normal thoracic organs were found in a 5-month-old miniature dachshund that presented with anorexia and weight loss. The case was diagnosed as partial heterotaxia. Gross observation revealed partial heterotaxia, polysplenia, abnormal lobulation of the liver, and absence of the greater omentum. These findings were consistent with those observed in asplenia-polysplenia syndrome in humans
