Myofibroblastic Sarcoma in Liver: a Case Report

We recently encountered a giant Myofibroblastic sarcoma (MS) exceeding 23 cm in diameter which had developed in the liver in a 27-year-old female, and which was surgically resected with gratifying results. On surveillance imaging, a giant mass was detected in the right lobe of the liver. One the basis of morphology and immunohistochemistry features, the diagnosis of intermediate-grade myofibroblastic sarcoma (MS) was established. MS is extremely rarely found in the abdominal cavity. It is almost impossible to make a definite diagnosis before operation. However, the possibility of sarcoma should be taken into account for liver mass according to multimodal imaging features of the mass, especially when the diagnosis of common hepatic tumor was not supported by signs on imaging. Relative characteristic features on multimodal images maybe helpful to considerate the possibility of MS. This is the first reported case to date.
