Two cases of heptatic hemangioma are reported in which multiple-radionuclide and ultrasound techniques were combined in the diagnostic process. Blood pool imaging rather than perfusion imaging proved to be the most definitive diagnostic procedure. The application of radionuclide and ultrasound studies in the differential diagnosis of focal lesions of the liver is discussed.

Benign liver tumors are common in general population, can be seen in 9% to 20% of individuals. Some of these tumors have a completely benign natural history and do not need to be resected, while others carry a risk of growth, hemorrhage, or malignant transformation and should be operatively removed. Obtaining a preoperative diagnosis is therefore critical, and this single factor remains the pri...

Hepatic hemangioma is frequently asymptomatic, and bleeding is rare, even in cases of large lesions. The authors report the case of a 31-year-old female patient presenting with acute abdominal pain, whose imaging studies have demonstrated hematoma in the left hepatic lobe associated with hemoperitoneum. The patient was submitted to left hepatectomy, with a final histopathological diagnosis of c...

Chylous ascites is rare in clinical practice. It is characterized by milky-appearing peritoneal fluid with a triglycerides concentration of >1.25 mmol/l (110 mg/dl). Its pathophysiology is related to a disruption in the normal lymphatic flow. It is more common after trauma (including post surgery), neoplasia or atypical infections such as tuberculosis or filariasis. Other rare medical causes ha...

In the past five years, 16 adults (10 females, age 25-61 years, mean 48) with giant cavernous hemangioma of the liver measuring 15-31 cm (mean-19) underwent surgery in a single Institution. Diagnosis was made with the help of multimodal investigations- ultrasound (US), computed tomography (CT), hepatic angiography, hepatic scintigraphy and fine needle biopsy. Ultrasound and CT had sensitivities...

The presence of visceral hemangiomas in the syndrome of multiple enchondromas and subcutaneous hemangiomas, also named Maffucci syndrome, is exceedingly rare; until now noncutaneous hemangiomas have been described in 4 patients: they were found in the tongue in one patient, in the oral cavity in the second patient, in both the oral cavity and the colon in the third patient, and in the spleen in...

This manuscript presents an automated classification approach to classify lesions into four categories of liver diseases, based on Computer Tomography (CT) images. The four diseases types are Cyst, Hemangioma, Hepatocellular carcinoma (HCC), and Metastasis. The novelty of the proposed approach is attributed to utilizing the difference of features (DOF) between the lesion area and the surroundin...

A 69-year-old man with an history of liver cirrhosis complicated by hepatocellular carcinoma treated by chemoembolization, moderate mitral insufficiency and chronic atrial fibrillation presented with a rounded calcified opacity in right upper abdomen at chest radiography. Abdominal computed tomography scan showed an omogeneous and complete uptake of lipiodol within the hepatocellular carcinoma,...
