Chronic Liver Lobe Torsion in a Cat
A 13 yr old castrated male blue British shorthair with a 3 mo history of vomiting was diagnosed with a left lateral liver lobe mass following abdominal ultrasonography. At the time of celiotomy, liver lobe torsion (LLT) of the left lateral lobe was also present. Histopathologic evaluation of the liver mass and associated lobe revealed extensive necrosis secondary to chronic torsion. This is the second reported case of LLT in a cat. Both cases were associated with liver masses. The cat presented in this case remained clinically normal 8 mo postoperatively following lobectomy of the affected lobe.
