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.
