ABSTRACT

Objective To improve the diagnostic accuracy of pediatric mesenchymal hamartoma of liver(M HL)by analyzing and summarizing the CT findings.Methods Five pediatric patients with M HL confirmed by postoperative pathology were enrolled,all patients underwent contrast-enhanced CT before operation.Results All lesions were located in the right lobe of liver.The tumor size ranged from 98 mm to 139 mm(mean size was 122 mm)in diameter.Four cases showed cystic and solid mixed masses,and one solid masses.After contrast administration,the substantial part of the mass and its septa showed enhancement while no enhancement was observed in the cystic part.No calcification was observed in the tumor.Conclusion M HL has some special CT characters.Most of M HL can be diagnosed combined with clinical practice as well as CT.
