摘　　要：BACKGROUND Low-grade myofibroblastic sarcoma(LGMS)is a rare malignant tumor.It has no specific clinical manifestations and commonly occurs in the head and neck,extremities and other body parts,with the liver not as its predisposing site.CASE SUMMARY We report a case report of a 58-year-old man with right upper abdominal pain for 11 d.Contrast-enhanced computed tomography(CECT),CE magnetic resonance imaging and CE ultrasound(US)all showed a cystic-solid mass in the right liver.As the initial clinical diagnosis was hepatic cystadenoma,surgical resection was performed,and the postoperative pathology indicated hepatic LGMS.The 3-mo follow-up showed favorable recovery of the patient.However,at 7-mo follow-up,two-dimensional US and CECT showed a suspected metastatic lesion in the rightmiddle abdomen.CONCLUSION Hepatic MS is particularly rare and easily misdiagnosed,more cases will contribute to the understanding and the diagnosis accuracy.
