Unlabelled: The aim of our study is to expose a practical screening and diagnosis strategy of HCC occuring in cirrhosis liver, which is nowadays a health public matter in Tunisia.

Methods: HCC routine screening in cirrhosis liver has been conducted every 6 months using a combination of abdominal sonography and serum alpha-foetoprotein levels. PCUS, CT scan or MRI have been performed each time a focal liver lesion was discovered in US, or in case of elevated serum alpha-foetoprotein levels.
