Ct findings of malignant fibrous histiocytoma

Purpose: To define the sites and CT findings of 45 MFH patients. Materials and Methods: The primary sites were: cranio-facial 16, trunk and extremity 12 and abdominal 17 (13 retroperitoneal). As seen on CT scans, the lesion is clear-margined and even when small, but, when large (42/50, >5 cm), it is uneven in consistency and apt to invade the nearby organs (75.8%). The CT findings of untreated and recurrent MFH are similar. Results: Enhanced CT scans may provide useful information such as medium to hyper-attenuation (78.8%), necrosis (60.6%) or involvement of para-nasal sinuses as expanding deformity (8/9 cases). Conclusions: CT scan is important to delineate the extent of MFH lesions of which the diagnosis is best ascertained by combining CT scan and histopathology. Enhanced CT scans can reveal much useful information.
