[Torsion of a liver cyst in a calf]

A 7-day-old male calf was presented because of an abdominal distension and a reduced feed intake. Sonographic examination showed a multi-chambered mass with anechoic content, separated by numerous hyperechoic septa in the ventral aspect of the abdomen. During diagnostic laparotomy, the cystic mass adhering to the diaphragmatic surface of the liver was determined to be a liver cyst with a 720°-torsion separating the cyst into two parts. A complete resection of the pedunculated cyst was achieved. The calf recovered completely and body-weight gain following surgery was typical for its age and breed. Histopathological examination of the cystic wall confirmed the diagnosis of a serosal liver cyst.
