Abstract
Background Simple hepatic cysts are common lesions in adults, but rare in children. Because of their benign nature, simple hepatic cysts may not be detected until they grow too large to be diagnosed and resected in a minimally invasive manner. Case presentation An 18-month-old girl presented with an enormous cyst occupying the entire abdomen. The beak sign on computed tomography revealed the hepatic origin of the cyst. The cyst was decompressed through the umbilicus, which was opened by the three-triangular-skin-flap technique, thus creating a working space that enabled laparoscopic surgery. The cyst was excised en bloc together with the attached hepatic parenchyma. Conclusions Giant simple hepatic cysts occupying the entire abdomen are rare in children. Of 14 reported cases, only 1 underwent laparoscopic treatment. We have herein reported another case of a giant simple hepatic cyst in which the beak sign on imaging and the three-triangular-skin-flap umbilical opening technique were useful for its diagnosis and laparoscopic excision, respectively. Complete excision is desirable because there is a possibility of recurrence or other diseases that require total removal, including hydatid cysts and mesenchymal hamartomas.
