An unusual aetiology of right-sided 'ping' in a lactating Holstein heifer

Entrapment of the caecunn by the ligamentum teres hepatis was encountered in a lactating Holstein heifer. This presented as a right-sided 'ping' in association with non-specific clinical signs. Visceral entrapments by various embryological structures have been reported previously. This case is remarkable in part because of the involvement of the caecum and in part because of the presence of the umbilical portion of the embryological remnant. This raises questions regarding the incidence of persistence of the distal portion of the falcifornn ligament and round ligament of the liver and the effect this may have on other abdominal conditions. It also prompts questions about the potential for movement of the caecum within the abdomen and conditions that predispose this occurrence.
