Abstract: Objective To describe the sonographic appearance of mesenchymal hamartoma of the liver(MHL)and to analyze the diagnostic value of ultrasound.Methods Eleven surgically and pathologically confirmed cases of MHL from January 2005 to May 2011 in the Beijing Children′s Hospital were retrospectively reviewed.Results Ultrasound examinations showed 9 cystic hamartomas,including 7 multiseptate cystic and 2 monocystic lesions.Of the 7 multiseptate cystic hamartomas,4 had a honeycomb appearance and 3 had irregularly-distributed multiple cysts with varied septations.Of the 2 monocystic hamartomas,1 had a large cystic portion while the other was mainly solid with approximately 4% cystic portion of the tumor.Two cases in this group were solid,presenting with a well-defined homogenous mass.Conclusions Ultrasonography is an effective imaging modality for the diagnosis for MHL.A mixed or a mainly-cystic liver mass found in a child less than 2 years old should be suspicious for MHL.
