Abstract
Cholangiography is the definitive imaging modality for assessing Cholangiocarcinoma. This study was designed to evaluate the ultrasound (US) features of cholangiocarcinomas and assess the accuracy of US in mapping tumor site when compared to cholangiography. Findings were correlated with patient survival. Thirty-one patients with an US diagnosis of cholangiocarcinoma underwent cholangiography. The US diagnosis was correct in 29 of 31 cases. Complete agreement with cholangiography occurred in 23 (78%) cases. In six patients, there was discrepancy over the precise tumor location. US diagnosis of cholangiocarcinoma had a high predictive value (0.94) and proved an accurate method of mapping tumor site. Lesions arising in the hilar region carried a worse prognosis (50% were dead within 80 days).
