An approach to managing the adult patient with a simple liver cyst

* Small liver cysts (<4 cm in size) have not been associated with the development of symptoms.
¶ For symptomatic patients, the choice of intervention is individualized and informed by the liver cyst location and size, patient comorbidities, prior abdominal surgery, local expertise, and patient preferences. Data from randomized trials comparing interventions are lacking.
Δ Percutaneous aspiration with sclerotherapy is a minimally invasive procedure in which ultrasound-guided drainage is followed by injection of a sclerosing agent, often ethanol.
◊ The choice of surgical procedure is informed by several factors including cyst location, prior abdominal surgery, and local expertise.
