Pelvic fused kidneys: magnetic resonance imaging and intravenous pyelogram correlation.

This is a case presentation of pelvic fused kidneys as demonstrated by intravenous pyelogram and magnetic resonance imaging (MRI). The authors wish to stress the importance of anatomical imaging with MRI in the coronal plane. No reconstruction is required as with computerized tomography.

Useful radiological signs in acute appendicitis in children.

Straight X-rays of 92 control patients with acute appendicitis and 92 control subjects were studied for radiographic abnormalities. Disturbance in intestinal gas pattern was the most common abnormality. Presence of a faecolith, free peritoneal fluid, scoliosis and a soft tissue mass were useful supporting signs. Loss of the properitoneal fat line and the right psoas outline were not reliable signs as they occurred with equal frequency in both groups.
