Abstract

Objective To evaluate the role of multidetector computed tomography (CT) in the detection of hepatocellular carcinoma (HCC) and its metastases regarding its radiological characteristics and sites of metastases. Background To discuss radiological criteria of HCC in contrast-enhanced CT. These criteria will help us to detect the tumor in the liver and sites of its extrahepatic metastases. Patients and methods We included in this study 218 patients already diagnosed as having HCC. Of them, 139 did not have any extrahepatic metastases and 79 patients had extrahepatic metastases by contrast-enhanced CT assessment. The patients underwent ultrasound examination, clinical examination, and contrast-enhanced CT. Extrahepatic metastases were evaluated by their radiological criteria (enhanced in arterial phase and washout in portal phase and delayed phase) and by their specific sites. Results There is a significant relationship between age of the patients and extrahepatic metastases, sites of extrahepatic metastases, grading of extrahepatic metastases according to TNM classification, sensitivity and specificity of CT in detection of metastases of HCC in comparison with the sizes of the detected lesions. Conclusion Multidetector CT has the main role in detection of HCC and its extrahepatic metastases.
