Caroli's disease: magnetic resonance imaging features.

Our objective was to describe the main aspects of MR imaging in Caroli's disease. Magnetic resonance cholangiography with a dynamic contrast-enhanced study was performed in nine patients with Caroli's disease. Bile duct abnormalities, lithiasis, dot signs, hepatic enhancement, renal abnormalities, and evidence of portal hypertension were evaluated.

MRI for evaluating congenital bile duct abnormalities.

Congenital bile duct diseases consist of ductal plate development abnormalities and are genetically determined. These biliary abnormalities are encountered mainly in congenital fibrocystic diseases, represented by congenital hepatic fibrosis and different forms of Caroli disease. On the other hand, polycystic hepatic diseases also present cystic abnormalities, which could be confused with biliary dilatations, especially in the perihilar area.

Chronic mesenteric ischemia: imaging and percutaneous treatment.

Chronic mesenteric ischemia (CMI) is rare and is often diagnosed late. Fatal malabsorption-related complications or acute ischemic events occur in the absence of treatment. Diagnosis depends on careful acquisition of a medical history and elimination of other conditions.

[Sinusoidal abnormalities of the liver: MR imaging features].

This article reviews the different MR features found in sinusoidal lesions of the liver parenchyma. The diagnosis of these abnormalities is mainly based on the pathologic examination. These diagnoses relate to numerous diseases including veno-occlusive disease, Budd-Chiari disease, peliosis, hepato-portal sclerosis, and portal intra-sinusoidal thrombosis.

MR cholangiography in the evaluation of hepatic and biliary abnormalities in autosomal dominant polycystic kidney disease: study of 93 patients.

Purpose: The purpose of this work was to conduct an MR cholangiography study of hepatobiliary abnormalities in autosomal dominant polycystic kidney disease (ADPKD) and to correlate these abnormalities with the risk of infection.

Method: Cystic and intrahepatic bile duct (IHBD) abnormalities identified by MR cholangiography in 93 ADPKD patients were studied retrospectively. A blind study of liver function tests, renal insufficiency, and infectious episodes was also carried out.
