    Abstract:
    Cases of common bile duct (CBD) wall thickening due to varicose dilation of intramural veins consequential to portal vein thrombosis (PVT) are rare and present a considerable differential diagnostic problem, as they can mimic cholangiocarcinoma. In such cases, colour Doppler ultrasound (CD US) is a very valuable diagnostic method. There are only a few reports in literature on CD US findings of collateral circulation in a thickened CBD wall following PVT. A patient with obstructive jaundice, a tumour of the pancreatic head, CBD wall thickening, and pre-existing PVT is presented. CD US demonstrated collateral circulation of the thrombosed portal vein in the thickened wall of the common bile duct, thus ruling out a mass in the CBD. Obstructive jaundice seldom occurs with choledocal varices. In this patient, the bile duct obstruction was due to the carcinoma of the pancreatic head.
