Cholangiolocellular carcinoma is a rare lesion, intermediate in type between hepatocellular and cholangio-cellular carcinoma. The radiologic findings of cholangiolocellular carcinomas have not been reported. We describe the ultrasound, CT, MR, and angiographic findings of a case of cholangiolocellular carcinoma not associated with liver cirrhosis.

Contrast-enhanced ultrasound (CEUS) represents a significant breakthrough in ultrasonography (US), and it is being increasingly used for the evaluation of focal liver lesions (FLLs). CEUS is unique in that it allows non-invasive assessment of liver perfusion in real time throughout the vascular phase, which has led to dramatic improvements in the diagnostic accuracy of US in the detection and characterization of FLLs, the choice of therapeutic procedures, and the evaluation of response. Currently, CEUS is included as a part of the suggested diagnostic work-up of FLLs, including in cirrhotic patients with hepatocellular carcinoma, resulting in better patient management and cost-effective delivery of therapy.

PURPOSE: To evaluate the usefulness of renal resistive index(RI) in patients with liver cirrhosis as an indicator for predicting hepatorenal syndrome. MATERIALS AND METHODS: Renal RIs of thirty cirrhotic patients were analyzed using the gray-scale and Doppler ultrasonograms. As a control group, eight normal subjects were alsoincluded. Renal RIs were measured at three sites of interlobar or arcuate arteries of both kidneys. The patients were divided into three groups (A, B, or C) according to the Child-Turcotte-Pugh classification and their serum BUN and creatinine levels were compared. We determined whether RIs of normal controls differed from those of cirrhotic patients or whether RIs of cirrhotic patients correlated with the Child-Turcotte-Pugh classification or BUN and creatinine levels. RESULTS: Mean RIs(0.63 +/-0.03) of normal subjects were statistically different from those(0.67 +/-0.05) of cirrhotic patients(P=0.009). RIs of group A(n=6), B(n=9) and C(n=15) were 0.65 +/-0.03,0.65 +/-0.04 and 0.70 +/-0.04, respectively. The ANOVA test revealed statistically significant differences between the three groups(F ratio=4.472, P=0.021). RIs did not correlate with BUN or creatinine levels. CONCLUSION: RI could be used as an index for predicting hepatorenal syndrome before the renal function becomes impaired.

Accurate assessment of the degree of liver fibrosis is important for estimating prognosis and deciding on an appropriate course of treatment for cases of chronic liver disease (CLD) with various etiologies. Because of the inherent limitations of liver biopsy, there is a great need for non-invasive and reliable tests that accurately estimate the degree of liver fibrosis. Ultrasound (US) elastography is considered a non-invasive, convenient, and precise technique to grade the degree of liver fibrosis by measuring liver stiffness. There are several commercial types of US elastography currently in use, namely, transient elastography, acoustic radiation force impulse imaging, supersonic shear-wave imaging, and real-time tissue elastography. Although the low reproducibility of measurements derived from operator-dependent performance remains a significant limitation of US elastography, this technique is nevertheless useful for diagnosing hepatic fibrosis in patients with CLD. Likewise, US elastography may also be used as a convenient surveillance method that can be performed by physicians at the patients' bedside to enable the estimation of the prognosis of patients with fatal complications related to CLD in a non-invasive manner.

Ultrasound is a non-invasive, real-time, inexpensive, radiation-free and easily repeatable method, usually used for liver imaging. In recent years, new ultrasound examination techniques for liver diseases such as contrast-enhanced ultrasound and elastography have been rapidly developed, which can effectively identify intrahepatic space-occupying lesions, assess the degree of liver fibrosis and portal hypertension, and monitor the effects of treatment. Therefore, these technologies play an important diagnostic role in clinical liver diseases and have therapeutic interventional value. This guideline classifies the instrument set-up, patient preparation, and physician examination methods through multimodal ultrasound examinations (gray-scale ultrasound, color Doppler ultrasound, contrast-enhanced ultrasound, elastic ultrasound) for liver diseases. In addition, liver diseases multimodal ultrasound technology diagnostic criteria for diffuse hepatic lesions (inflammatory lesions, fibrosis, and sclerosis), multiple space-occupying lesions, and interventional procedures have been defined and standardized. Concurrently, we also recommend the ultrasound monitoring time interval and diagnostic report writing standard for liver diseases.
