[Gallbladder agenesis: a diagnostic problem?].

A rare case of an agenesis of the gallbladder in combination with cardiac malformation (anomalous pulmonary venous return with associated atrial septal defect) is reported. Despite modern diagnostic methods this agenesis which is often combined with a variety of malformations is first realized during operation or postmortem. Combinations of atypical clinical signs and sonografical or radiological absence of the gallbladder ("vésicule exclue") should point at agenesia of the gallbladder and to look for further malformations.
