We present a case of congenital listeriosis in a twin pregnancy. Prese
ntation was prompted by decreased fetal movements and an ultrasound ex
amination which demonstrated features similar to those observed in an
adult with inflammatory conditions of the bowel, namely, small amounts
of ascites, dilated loops of bowel and thickening of the bowel wall.
Such ultrasound signs may be useful in consideration of the diagnosis
of congenital infection and prompt diagnostic tests and appropriate in
terventions that assist in early therapy. (C) 1998 John Wiley & Sons,
