RESUMEN
In a case of monoamniotic twinning, amniography was used to confirm the diagnosis. This modality, old but now employed infrequently, helps establish the absence of a dividing membrane and complements currently used ultrasound diagnostic methods. A successful outcome resulted. Amniography should be considered a useful diagnostic modality in the management of twin gestations and not be relegated to the past.

An antepartum diagnosis of vasa previa was considered in a patient in whom ultrasound revealed pulsatile loops of cord overlying the cervical os. This diagnosis was confirmed at the time of cesarean delivery. We offer a literature review of vasa previa and make recommendations for using ultrasonography to diagnose vasa previa.

Sonographic examination of the gallbladder in two patients with preeclampsia and right upper quadrant pain demonstrated notable thickening of the gallbladder wall. The sonographic abnormality and clinical symptoms completely resolved after delivery and/or medical management of the preeclampsia. This finding is probably secondary to the hypoalbuminemia characteristic of preeclampsia and should not be mistaken for intrinsic gallbladder disease.

The nephrogram is a sensitive indicator of renovascular compromise. An infrequently reported but characteristic nephrographic abnormality is the cortical rim nephrogram. This "rim sign" refers to a thin nephrographic rim outlining a kidney with an otherwise faint nephrogram. We report 2 patients with this nephrographic appearance due to acute renal artery insult. The rim nephrogram is a reliable sign of underperfusion of the kidney. It is dependent on collateral capsular vessels supplying the outer renal cortex. Underperfusion can be due to a primary renal artery problem or secondary to compromise of renal artery perfusion because of elevated interstitial or tubular pressure in the kidney. The sign has not been described with systemic circulatory problems.
