[Cruveilhier-von Baumgarten-syndrom. Evaluation by ultrasound and computerized tomography (author's transl)]

A desobliterated umbilical vein was sonographically detected in a 52 years old man suffering from liver cirrhosis. The vein was seen in the sonogram as a tubelike, sharply outlined, echofree formation, measuring 1-1,5 cm in diameter and located at the dorsal site of the abdominal wall; a circumscribed dilatation in the cranial part of the vein was remarkable. The findings were confirmed by CT-examination. Density values of the vein increased after contrast injection from 50 HE to 80 HE. The vessel could be followed along its way in the falciforme ligament and caudad of the umbilicus.
