Pitfalls in cervical ectopic pregnancy diagnosis by emergency physicians using bedside ultrasonography.

Pelvic pain and vaginal bleeding are common complaints in pregnant women presenting to emergency department. Cervical ectopic pregnancy (EP) is a rare type of EP, with a higher likelihood of complications if missed. Its sonographic findings can be difficult to distinguish from normal pregnancy or an abortion in progress.

Dynamic changes of common bile duct diameter during an episode of biliary colic, documented by ultrasonography.

Common bile duct stones frequently accompany gallstones and can be identified by a variety of imaging modalities. Little is known about the time course of dilatation of the common bile duct after acute obstruction or of normalization after spontaneous passage of an obstructing stone. We describe a case showing rapid fluctuations in common bile duct diameter during 72 hours in a patient presenting with epigastric pain and vomiting.
