    Notes: Abstract Intramural perforation of the colon proximal to the rectosigmoid is a rare complication of the barium enema examination. We present a case in which air and barium entered the wall of the transverse colon, and then dissected through the transverse mesocolon during double-contrast barium enema in an asymptomatic patient with no known underlying colonic disease.

    Notes: Abstract Flattening of the infrahepatic inferior vena cava (IVC) on postcontrast computed tomographic (CT) scans has been reported as a sign of severe hypovolemia. The significance of this finding on unenhanced CT scans, however, has not been reported. We retro-spectively studied 60 consecutive outpatient abdominal CT scans in which both unenhanced and postcontrast sequences were performed. Flattening of the infrahepatic IVC on unenhanced CT images was noted in six patients (10%) without evidence of hypovolemia or extrinsic IVC compression. The degree of IVC fullness increased in 43 study patients overall (72%) after contrast administration. We propose several mechanisms for postcontrast IVC distention and conclude that a flattened infrahepatic IVC on unenhanced CT scans does not indicate hypovolemia in the absence of other suggestive clinical or CT findings.

    Notes: Abstract Plain radiographic findings in appendicitis have been neglected somewhat since the advent of cross-sectional imaging studies. Nevertheless, a definitive diagnosis may be made with conventional radiography in selected cases. The most important finding is the recognition of an appendicolith, which, like the appendiceal lumen, may be located far from its expected position in the right lower quadrant. Air in the appendix is a normal finding, except when the lumen is dilated. Ancillary findings, such as cecal dilatation, are nonspecific. Recognition of appendiceal abscess depends upon demonstration of a mass and/or extraluminal air in the form of large lucencies or small bubbles.
