Abstract

Hepatic Hemangioendothelioma (HHE) has a wide clinical spectrum, from a state of spontaneous regression to life-threatening condition. In addition, many cases require surgical treatment. We report on a case of HHE found by chance during a laparoscopic percutaneous extraperitoneal closure (LPEC) operation, showing spontaneous regression without any therapy.<br>A one-month-old girl underwent LPEC operation for a left external inguinal hernia with sliding ovary in our institution. Under laparoscopic observation, multiple hepatic nodules were discovered unexpectedly. Abdominal ultrasonography, enhanced CT and MRI after the operation concluded a diagnosis of HHE. Since the nodules had spread to the liver, surgical treatment was considered to be difficult. There were no symptoms in this case and HHE sometimes regresses spontaneously, we therefore observed its natural course followed by imaging examinations. The foci showed reduction in size and indistinctness 6 months later. Two years and one month later, the tumors disappeared completely on MRI.
