Liver Lobe Torsion and Abscess

Abstract

Liver lobe torsion is a rare condition, but has been reported in dogs, cats, horses, pigs, rabbits, otters, and humans. Left lateral liver lobe torsion is reported to be the most common lobe affected in one study, accounting for nearly 50% of all cases. Nonspecific clinical signs are typical of liver lobe torsion. Ultrasound is a sensitive imaging modality used to diagnose liver lobe torsion. Postoperatively, the patient may develop cardiac arrhythmias and therefore the heart should be monitored with continuous electrocardiogram and a plan formulated to treat arrhythmias if needed. Liver abscesses are uncommon in dogs and cats. In earlier studies, the diagnosis of liver abscessation was based on necropsy findings. Ultrasound is considered the diagnostic modality of choice, as it is economical, provides a rapid diagnosis, can be used for diagnostic and therapeutic needle aspiration of the abscess, and permits evaluation of regional lymph nodes.
