case_images: Ultrasonography demonstrated a huge hyperechoic round mass with a well defined smooth contour and several small hypoechoic foci in it(Fig. 1).
case_images: CT: An enhanced round mass with multiple irregular fat dense areas and sharply defined margin.

case_images: CT showed an enhanced round mass with multiple irregular fat dense areas and sharply defined margin(Fig. 2).
case_images: MRI: On T1 weighted image, the mass shows hyper-and isodensity lesion compared to normal liver, but on T2 weighted image it shows bright signal intensity.

case_images: On dynamic study, the mass was demonstrated to be inhomogenous and showed prolonged enhancement, which pattern seemed to be atypical for hemangioma(Fig. 3).
case_images: Angio graphy: celiac angiography demonstrated a large hyper-vascular tumor and dilated hepatic artery and vascular pooling in the lower lateral portion.

case_images: The resected specimen was measured 29.0 x 22.0 x 6.5cm and weighed 2,500g(Fig. 5).
case_images: The cut surface of the specimen revealed 25. 0 x 20.0cm soft, dark reddish and partly yellowish tumor completely surrounded by capsule.

case_images: The cut surface of the specimen showed 25.0 x 20.0cm soft, dark reddish and partly yellowish tumor completely surrounded by capsule(Fig. 6).
case_images: The tumor is mainly composed of fatty tissue and blood vessels (H & E, x 100).
