Hepatic metastasis disguised as fat spared area in the background of fatty liver: Detection on FDG PET/CT

Abstract: Area of fat sparing in fatty liver is known to pose a diagnostic challenge in an oncological setting, especially in cancers with higher propensity for liver metastases. We report an unusual appearance of hepatic metastases in a fat spared area, on both computed tomography (CT) and positron emission tomography (PET), in a combined 18 fluorine-fluorodeoxyglucose (18 F-FDG) PET/CT study done in metastatic adenocarcinoma of colon.

“…Fatty liver affects usually the liver in a homogeneous way (68%). Thus, it appears hyperechoic on ultrasonography, hypodense on non contrast enhanced CT images, hypointense on opposed phase T1 weighted MRI and on fat suppressed MRI sequence [ 9 , 10 ]. The diagnostic problem occurs when the fatty infiltration is not diffuse.…”
