Abstract:Objective: To analyze MRI findings of atypical liver abscesses and to evaluate diagnostic value of enhanced MRI. Methods: Thirty two atypical liver abscesses were proved by pathology and follow up after clinical therapy, their MRI findings before and after contrast administration were retrospectively analyzed and correlated with operation and pathology. Results: There were 3 types of atypical liver abscesses on MRI. Five lesions (15.63%) appeared as a small cavity less than 2.2 cm and showed rim enhancement of wall only after contrast. Nineteen lesions (59.37%) were composed of granulomatous and fibrous tissue and interspersed with small area of liquid and coagulative necrosis. After contrast, granulomatous and fibrous tissue showed obviously delayed enhancement. Eight lesions (25%) appeared as a mass and were circumscribed with the complete capsule that showed rim enhancement in 6 lesions. Eighteen atypical abscesses (56.24%) were difficult to diagnose accurately with only plain MRI.Twenty eight atypical abscesses (87.5%) were correctly diagnosed with combination of plain with enhanced MRI. Conclusion: Atypical MRI findings of liver abscesses result from individual differences of pathologic changes and regressions. The application of enhanced MRI can improve the diagnostic accuracy for atypical liver abscesses.
