Abstract

Hemangioma is the most common benign liver tumor and the second most common liver tumor after metastases. Large hemangiomas are often heterogeneous. When they exceed 4 cm in diameter, they are termed giant hemangiomas. These giant hemangiomas often present heterogeneous patterns. These heterogeneous appearances are shown because of intratumoral changes due to several degenerative phenomena. PET/CT is reported to be useful for the differentiation of benign from malignant liver lesions. We report the case of a large hepatic hemangioma characterized by high FDG uptake.

Summary

Introduction

Hemangioma is the most common benign liver tumor and the second most common liver tumor after metastases. These findings suggested for a giant hemangioma, the most common benign liver tumor [1] (Figure 1). Large hemangiomas often present heterogeneous patterns and these heterogeneous appearances are shown because of intratumoral changes such as hemorrhage, thrombosis, extensive hyalinization, necrosis and fibrosis [2]. PET/CT is reported to be useful for the differentiation of benign from malignant liver lesions [3]. PET/CT scan demonstrated high FDG uptake compared to normal liver parenchyma.
