Acute Cytomegalovirus Infection as a Rare Cause of Portal Vein Thrombosis with Small Bowel Infarction in an Immunocompetent Patient.

Portal vein thrombosis (PVT) refers to thrombosis that develops in the trunk of the portal vein including its right and left intrahepatic branches and may even extend to the splenic or superior mesenteric veins. PVT due to Cytomegalovirus (CMV) infection is a rare complication, scarcely described in English literature. We present a case of a 58-year-old immunocompetent patient with PVT and small bowel ischemia.

Food Impaction in a 9-Year-Old Boy.

A 9-year-old boy was admitted to the emergency department because of repetitive vomiting and loss of appetite for 4 days. There was peristalsis present and laboratory tests were normal.

Unusual presentation of ovarian pathology on CT.

A prospective study including seventy-seven consecutive patients suspected of having ovarian tumoral or pseudotumoral pathology on CT was carried out. Fifty-nine patients had surgery with histological diagnosis. When comparing the CT and histological findings in benign and malignant lesions we obtained an overall accuracy of 95% with only three misdiagnosed cases on CT.

Magnetic resonance arthrography of the scapulohumeral joint in dogs, using gadopentetate dimeglumine.

Six scapulohumeral joints (3 normal joints and 3 joints with radiographic evidence of osteochondrosis) underwent conventional magnetic resonance (MR) imaging and MR scapulohumeral arthrography to evaluate delineation of the articular cartilage. The MR arthrography was performed, using 5 ml of 500 microM gadopentetate dimeglumine (Gd-DTPA) as a contrast medium. Delineation of normal articular cartilage and cartilage defects was less accurate after intra-articular administration of Gd-DTPA.

Randomised double blind trial of the safety and efficacy of two gadolinium complexes (Gd-DTPA and Gd-DOTA).

The main difference between macrocyclic Gd-DOTA and linear Gd-DTPA complexes is the greater stability of the former which theoretically might reduce biological interactions in man. To evaluate the clinical relevance of this property, 300 unselected neurological patients were included in a randomised double-blind comparison involving five European centres, focused mainly on the tolerance of these two contrast media. Clinical tolerance was assessed immediately after the procedure and 24 h later.

Pathologic correlations with magnetic resonance images of osteochondrosis lesions in canine shoulders.

Twelve shoulders in 6 dogs with clinical and radiographic evidence of osteochondrosis were examined by magnetic resonance imaging performed on a 0.5-T superconductive system. Scans were obtained with 5-mm-thick slices and 0.
