Abstract Objective: To improve the diagnostic accuracy of mesenchymal hamartoma of liver(MHL) by analyzing and summarizing the CT/MR display features. Methods: Ten patients(4 male and 6 female, age range from 11 months to 60 months) underwent dynamic contrast-enhanced CT or MR examination. Main symptoms were abdominal mass(5 cases), abdominal pain(5 cases), AFP increased slightly in 2 cases. Results: Five masses located at the right lobe of liver, 3 located at the left lobe, the others located at both right and left lobe. The lesions size range from 8.1 cm to 17.8 cm, (13.26±3.18) cm on average. There was correlation between the CT/MR findings of MHL and the proportion of cystic or solid component in the masses. Seven cases were cystic-solid mixed, three cases were solid. After contrast administration, the solid component and the septa of the masses showed enhancement while no enhancement was assessed in the cystic component. In MR images, the solid component and the septa of the masses were shown hypointense on T1WI and T2WI, the cystic component was shown hyperintense on T2WI. Conclusion: MHL has some special characteristics, most of MHL can be diagnosed when combined with the clinical information and CT/MR images.
