Gallstone ileus: CT findings.

Gallstone ileus is a rare complication of recurrent gallstone cholecystitis. The classic radiographic triad of small bowel obstruction, pneumobilia and ectopic gallstone on abdominal plain radiograph is described with CT imaging. Because of the better resolution of CT compared with abdominal radiography and its recent accession to emergency use, radiologists should be aware of CT findings of gallstone ileus.

Congenital extra-hepatic portocaval shunt. Concerning a case of antenatal diagnosis.

The authors report a case of congenital extra-hepatic portocaval shunt in a two-year-old girl. While pointed out antenatally by ultrasound and suspected by a follow-up ultrasound at the age of two years, this anomaly could be confirmed only by coupled ultrasound scanning and color Doppler, which allows for dynamic anatomic and morphologic evaluation. Comments concern mainly the embryologic hypothesis and the clinical tolerance of this malformation (because no therapeutic measures were adopted).
