title: Giant hepatic hemangiomas: diagnostic and therapeutic dilemmas.
abstract: This report describes four cases of surgically treated giant hepatic hemangiomas which illustrate some diagnostic and therapeutic difficulties encountered in the management of this condition. An important diagnostic triad has emerged, which should alert the physician to the possibility of a complicated hepatic hemangioma: the clinical signs of an acute inflammatory liver process contrasted with a normal white blood cell count and liver function tests. Hemangiomas of the left lobe were either missed or poorly demonstrated on selective hepatic angiographic examination, and in two patients the diagnosis was made only at the time of laparotomy. Hepatic resection was successfully performed in all patients; there was minimal morbidity and none of the patients died. In two patients with multiple hemangiomas, only symptomatic or easily resectable lesions were removed. All patients are alive and well; three have been followed up for more than 5 years. We conclude that resection in asymptomatic cases should be carried out only in those cases that require a diagnostic laparotomy and in those where the lesion is easily resectable. The majority of patients with symptomatic and complicated tumors should undergo resection, but even in these patients continued conservative treatment is appropriate when the risk of major resection outweighs the small risk of live-threatening bleeding.
