(with related portal hypertension) Cirrhosis is late state of hepatic fibrosis—late cirrhosis is generally irreversible – Distorted hepatic architecture and regenerative nodules Can be caused by a litany of diseases, including: – Alcoholic liver disease, Hep B/C, NASH (?), PBC, PSC, autoimmune hepatitis, hemochromatosis, Wilson’s disease, alpha-1-antitrypsin deficiency, cardiac cirrhosis Physical findings include: – Spider angiomata, gynecomastia, palmar erythema, nail changes, clubbing/HPOA, Dupuytren’s contracture, HSM, testicular atrophy, ascites, caput medusae, jaundice, fetor hepaticus, asterixis – Can lead to HCC Goldberg, E and S Chopra. ―Diagnostic approach to the patient with cirrhosis.‖ Uptodate.com. Accessed November 19, 2008. Role of Radiology Cirrhosis is a pathologic diagnosis, so radiology can only suggest the diagnosis – Can evaluate for complications of cirrhosis (e.g. ascites, HCC, hepatic/portal vein thrombosis, etc.) and, rarely, can reveal etiology of cirrhosis Ultrasound is routinely used in evaluation—can be used as screening tool for HCC and portal hypertension – ―Stiffness measurement‖—increased liver scarring causes increased liver ―stiffness‖—a newer ultrasound device is used to evaluate – Very helpful with advanced fibrosis Little role or unclear role for CT/MRI—MRI may be helpful in determining Child-Pugh score, but use is still limited Goldberg, E and S Chopra. ―Diagnostic approach to the patient with cirrhosis.‖ Uptodate.com.
