Sonographic findings of malignant fibrous histiocytoma of the mesentery-report of two cases.

We present two cases of malignant fibrous histiocytoma (MFH) of the mesentery. A whorled internal structure observed on sonogram and large feeding and draining vessels demonstrated on color Doppler sonogram in these cases were worth noticing. When sonography reveals an abdominal tumor with such findings, although very rare, the possibility of a MFH of the mesentery must be considered. We also review briefly the literature.
