PURPOSE: To determine the imaging characteristics of fulminant hepatic failure at serial computed tomography (CT) and to assess if any CT findings have prognostic value. MATERIALS AND METHODS: In 40 patients, 207 CT scans were analyzed retrospectively. Thirty-four patients had fulminant hepatic failure (acute in seven and subacute in 27), and six had late-onset hepatic failure. Twenty-one patients died of hepatic failure. CT was performed soon after the onset of coma and repeated weekly. Liver volume was measured by tracing the hepatic contour and summing the areas to estimate whole-liver volume. RESULTS: Liver volumes in survivors (n = 19) and nonsurvivors (n = 21), respectively, were 1,090 cm3 +/- 300 and 830 cm3 +/- 240 at initial CT and 1,130 cm3 +/- 310 and 700 cm3 +/- 280 at last CT (P = .0001). III-defined hypoattenuating areas were noted in 20 patients and were distributed in a solitary (n = 13), multiple (n = 6), or diffuse (n = 1) pattern. At follow-up CT, the area of hypoattenuation increased in six patients (five nonsurvivors) and disappeared or markedly decreased in four survivors. An increase in or late occurrence of ascites was noted in 15 patients (14 nonsurvivors, P = .0001). CONCLUSION: Liver volumes at the initial and last CT examinations and an increase in or late occurrence of ascites are useful prognostic findings.
