Hepatic mesenchymal hamartoma: The role of radiology in diagnosis and management

Abstract

Hepatic mesenchymal hamartoma is an uncommon tumor composed of myxoid mesenchymal tissue with fluid accumulation. Here, we report a case of hepatic mesenchymal hamartoma in a 3-year-old patient who was referred to the hospital with abdominal pain and a slight fever. An abdominal ultrasound suggested a liver abscess; however, computed tomography revealed a mass with both cystic and solid components. Liver biopsy confirmed hepatic mesenchymal hamartoma, and this patient underwent the complete removal of this tumor.

Mesenchymal hepatic hamartoma: A rare case of severe respiratory distress in a neonate

“…Hepatic mesenchymal hamartoma is a benign tumor composed of myxoid mesenchymal tissue with fluid accumulation 6 . Since its initial characterization by Edmondson in 1956, HM has been reported with an incidence of approximately 0.7 cases per million population annually 7,8 .…”

Diagnóstico prenatal de hamartoma mesenquimatoso hepático fetal

“…El hepatoblastoma y el carcinoma hepatocelular, junto al HMH, están asociados con mayor producción fetal de alfafetoproteína, lo que explicaría la elevación de las concentraciones maternas por paso transplacentario. También se ha informado elevaciones de la gonadotropina coriónica (13) . No obstante, las elevaciones de las concentraciones son inespecíficas y están asociadas con varias anomalías congénitas.…”
