Spontaneously Resolving of Huge Simple Hepatic Cyst

Abstract

Simple hepatic cysts are common benign liver lesions that usually have no malignant capability. They are generally asymptomatic and are often found incidentally by abdominal imaging procedures. Treatment becomes necessary, however, when huge hepatic cysts cause symptoms and develop complications, such as hemorrhage, adjacent organ damage, and infection. Several therapeutic options have been performed for symptomatic and huge cysts, including the aspiration of cystic fluid, infusion of various sclerosing agents, and surgical intervention. The optimal management of huge hepatic cysts is controversial and each option has its complications and limitations. This paper reports a case of a 66-year-old woman diagnosed with a simple hepatic cyst 2 years earlier, who was referred to hospital due to abdominal pain. The diagnosis was a huge hepatic cyst with symptoms by abdominal imaging studies. During the follow-up period, the huge cysts resolved spontaneously without treatment.
