torsion of a giant pedunculated hemangioma of the liver presenting with acute abdomen: a case report

introduction hemangioma is the most common benign tumor of the liver. most cases are asymptomatic and do not require treatment. a hemangioma can rarely be pedunculated; as a result, it may undergo torsion and infarction, which can make it symptomatic. case presentation we report the case of a 45-year-old woman with acute abdominal pain due to torsion of a giant pedunculated hepatic hemangioma around its vascular stalk. conclusions pedunculated hemangioma of the liver is an uncommon benign tumor, a rare differential diagnosis for a mass located in the upper abdomen. all incidentally detected pedunculated hemangiomas must be surgically managed, as these have a tendency to become torsioned, and there is also a risk of malignancy or rupture.
