3. 3. Fig GI 76-1 Focal hepatic steatosis. (A) In- phase T1-weighted MR image shows peripheral high-intensity foci (arrow). (B) On the opposed-phase image, there is a uniform decrease in the signal intensity of the foci (arrow).137
4. 4. Fig GI 76-2 Omental packing. Contrast CT scan shows a hepatic pseudomass (arrow), a common postoperative finding.137
5. 5. Fig GI 76-3 Hepatic adenoma. Unenhanced CT scan shows multiple fat-attenuation lesions within the liver.137
6. 6. Fig GI 76-4 Hepatic adenoma. (A) In-phase T1- weighted MR image shows a large hypointense mass in the right lobe of the liver (arrow). On the out-of-phase image, there is a homogeneous decrease in the signal intensity of the fat-containing lesion.137
7. 7. Fig GI 76-5 Angiomyolipoma. Contrast CT scan demonstrates a well-circumscribed, heterogeneous tumor of the right lobe of the liver that contains foci of fat (arrow).137
8. 8. Fig GI 76-6 Hepatic invasion by a retroperitoneal teratoma. Contrast CT scan shows a predominantly fatty mass with a peripheral rim and central chunky calcification (arrow).137
9. 9. Fig GI 76-7 Adrenal rest tumor. CT scan shows a heterogeneous lesion in the right lobe that contains macroscopic fat (arrow).137
10. 10. Fig GI 76-8 Hepatocellular carcinoma. Contrast CT scan shows patchy macroscopic fat deposition () in a large, heterogeneously enhancing hepatoma.137
