In this case report, a female child of 10 years old presented with pain epigastrium and with sonographic features of acute cholecystitis. Later on, the focal mass in the liver was diagnosed by Magnetic Resonance Imaging (MRI) examination and proved by the biopsy as focal nodular hyperplasia (FNH), a benign focal response of the liver and a hepatic mass. Although focal nodular hyperplasia is rar...

Multiple focal liver lesions can generate diagnosis difficulties in daily practice. This paper present the case of a 53 years old patient with multiple hyperechoic liver lesions suggestive for hepatic hemangiomas, detected during the ultrasonographic exam. Contrast enhanced ultrasonography indicated focal hepatic steatosis, while computed tomography proposed possible liver metastasis. The histo...

We report two cases of focal nodular hyperplasia in patients following gadoxetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging confirmed with histopathology. These cases showed an atypical pattern during the delayed-hepatobiliary phase after the injection of gadoxetic acid. One case showed a total defect, and the other showed a peripheral ring-like enhancement without a visible central...

Twelve hepatocellular nodules were characterized in the resected livers from 3 patients (2 men and a woman) with alcoholic cirrhosis. Imaging techniques suggested that the nodules were hypervascular and may be hepatocellular carcinoma. Five nodules (4-31 mm in diameter) were serum amyloid A-positive hepatocellular neoplasm, which shares features with inflammatory hepatocellular adenoma. The rem...

Focal nodular hyperplasia (FNH) is characterized by the presence a central scar with radiating fibrous septa. Our case had a capsular retraction, which was the result of an extension of the central scar to the surface. In addition, a hypointense scar on the T2-weighted image and a minimal enhancing central scar on the enhanced T1-weighted image, which was due to dense, sclerotic collagenous tis...

Focal nodular hyperplasia (FNH) is a benign tumour of the liver, occurring in 0.6-3% of the general population. Most lesions are diagnosed incidentally. With the increasing use and improvement of diagnostic imaging, FNH is being observed more often. It has been shown, using radiological approaches, that most FNH remain stable, or even regress, over a long follow-up period. In addition, it is ex...
