Cystic lesions of the liver represent a heterogeneous group of disorders, which differ in etiology, prevalence, and clinical manifestations. Most liver cysts are found incidentally on imaging studies and tend to have a benign course. A minority can cause symptoms and rarely may be associated with serious morbidity and mortality. Larger cysts are more likely to be symptomatic and cause complications such as spontaneous hemorrhage, rupture into the peritoneal cavityor bile duct, infection, and compression of the biliary tree. Specific types of hepatic cysts may have unique complications such as malignant transformation in the case of a mucinous cystic neoplasm or a ciliated hepatic foregut cyst, or anaphylactic shock due to a hydatid cyst. Some of these complications may occasionally mandate surgical intervention. Methods: 72 years old male patient who presents with transfictive abdominal pain in upper left quadrant, abdominal distention, fever and malaise with a palpable tumor in most of the upper abdomen, which is painful, with no evidence of peritoneal irritation. Ultrasound and CT revealed a giant hepatic cyst. Laparoscopy was performed finding irregular cystic liver tumor aspirating 800 mL of seropurulent material, there where no complications, The postoperative outcome was uneventful as the patient made a full recovery. Results: Even though most of the hepatic cysts are benign, better to undergo investigations such as CT, Histopathology examination to rule out differential diagnosis and to alleviate any further complications.The treatment for this entity is not yet well established, laparoscopic surgery has brought good results for the resolution of hepatic cysts, however, there have been technical difficulties principally in cysts located in deep or posterior segments.
