We present a rare case of a focal intrahepatic extramedullary hematopoiesis (EMH) that mimicked a hypervascular hepatic neoplasm in a 33-year-old woman with idiopathic myelofibrosis. The lesion showed homogeneous and persistent enhancement on both contrast-enhanced CT and gadolinium-enhanced dynamic MR imaging. The lesion did not demonstrate an apparent signal drop on a T2-weighted sequence fol...

Gadolinium-enhanced magnetic resonance for the evaluation of hepatic lesions is increasingly being used in clinical practice, especially in patients with suspicious focal lesions, whether benign or malignant. In regard to hepatocellular carcinoma, the diagnostic performance of magnetic resonance through the «conventional» protocols and multi-detector computerized tomography consisting of multip...

PURPOSE We aimed to evaluate the therapeutic effect and safety of transarterial embolization using bleomycin-iodinated oil and polyvinyl alcohol particles for the treatment of symptomatic hepatic focal nodular hyperplasia (FNH). METHODS This retrospective study included 23 consecutive patients with symptomatic hepatic FNH, who underwent embolization using bleomycin-iodinated oil and polyvinyl...

A variety of neoplasms and nonneoplastic hepatic lesions have been noted in winter flounder, Pseudopleuronectes americanus, from Boston Harbor, Massachusetts. Inflammatory lesions include cholangiitis, pericholangiitis, pericholangial fibrosis, hepatitis, and pancreatitis. Necrotic lesions consist essentially of focal coagulative necrosis and a distinctive vacuolated cell lesion of the hepatic ...

BACKGROUND Hepatic pseudolesions detected by helical computed tomography (CT) are not rare, but it is difficult to make a final diagnosis when the hepatic lesion is complicated by the presence of greatly elevated alpha fetoprotein (AFP). Clinical treatment of non-typical hepatic pseudolesions complicated by greatly elevated AFP should confirm the diagnosis and minimize trauma. CASE PRESENTATI...

OBJECTIVES The aim of this study was to assess the diagnostic performance of a dynamic, multiphasic contrast-enhanced volume-interpolated sequence with advanced parallel imaging techniques, Dixon fat saturation, and view sharing with 5 hepatic arterial subphases for the detection of focal liver lesions. MATERIALS AND METHODS Twenty-four consecutive patients (13 females, 11 males; mean [SD] ag...

Hepatocellular carcinoma (HCC) is the leading cause of death among patients with cirrhosis. Therefore, a focal hepatic lesion in a patient with cirrhosis must always be investigated for its high risk of cancer. However, when hepatic lesions in an imaging exam do not present the typical characteristics of a malignant or a benignant tumor, diagnosis may be a challenge. The biopsy can be used in t...

A 22-year-old female patient sought medical care due to an asymptomatic solid nodule in the liver, incidentally diagnosed by abdominal ultrasound. She reported the use of an estrogen-based oral contraceptive for approximately 3 years. She denied smoking or alcohol drinking. Her mother had a history of nonalcoholic steato-hepatitis and her maternal grandmother had a hepatic hemangioma. Physical ...

OBJECTIVE To evaluate the diagnostic yield of MRI performed for characterization of focal hepatic lesions that are interpreted as indeterminate on CT. PATIENTS AND METHODS In a retrospective investigation, 124 indeterminate focal hepatic lesions in 96 patients were identified on CT examinations over 5 years from 1997 to 2001. All patients had MRI performed for the liver within 6 weeks of thei...
