A 53-year-old man with a history of nausea and elevated liver functions presented to our clinic. A CT scan showed a small tumor in the right lobe of the liver. Fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography confirm abnormal metabolic activity with a high standardized uptake value of 7.3 in the lesion. These findings could indicate a malignancy such as well-differentiated ...

OBJECTIVE The kinetic analysis of (11)C-acetate PET provides more information than routine one time-point static imaging. This study aims to investigate the potential of dynamic (11)C-acetate hepatic PET imaging to improve the diagnosis of hepatocellular carcinoma (HCC) and benign liver lesions by using compartmental kinetic modeling and discriminant analysis. METHODS Twenty-two patients were...

Perfusion computed tomography (CT) has a great potential for determining hepatic and portal blood flow; it offers the advantages of quantitative determination of lesion hemodynamics, distinguishing malignant and benign processes, as well as providing morphological data. Many studies have reported the use of this method in the assessment of hepatic tumors, hepatic fibrosis associated with chroni...

Hepatic toxocariasis is visceral larva migrans caused by Toxocara. We report a case of hepatic toxocariasis detected incidentally during a health checkup. The patient had elevated levels of eosinophils, total IgE, and anti-Toxocara IgG antibodies. On contrast-enhanced computed tomography (CT) imaging he had a single, 2.16 cm, oval, ill-defined, low-attenuation hepatic nodule which was best appr...

a 65 years old male presented with abdominal pain (r.u.q) and constipation, associated with weight loss and anorexia since 40 days prior to admission. serum biochemical tests were normal. colonoscopy showed hemorrhagic polypoid lesion in the cecum. barium enema revealed filling defect in the cecum. sonography revealed a target-shaped lesion (3cm×2.5cm) in upper segment of the right hepatic lobe...

Hepatic artery aneurysm was firstly described at autopsy in 1809. It can present as a duodenal submucosal lesion caused by extra-luminal compression. Most cases of common hepatic artery aneurysms with external compression of duodenum are asymptomatic until rupture with intestinal hemorrhage. Such cases had been reported with poor prognosis if diagnosis and treatment were delayed. Hence, the man...

topic hematopoiesis that is a common feature of chronic bone marrow failure. However, EMH is rarely encountered in general radiological practice (1). A mass-like EMH lesion in the liver is an atypical presentation. Furthermore, hepatic periportal EMH is less common than other types of focal hepatic EMH (2). We present the sonographic and CT findings of a histologically confirmed case of hepatic...

   A 36-year-old woman with right upper quadrant abdominal pain since three months previously and no other significant medical history was referred for evaluation of an abdominal mass. Upon clinical examination, a large palpable mass in the mid -upper abdominal area was noted. Abdominal ultrasound and spiral CT-scan showed a large hepatic mass in the left liver lobe. ...
