“…This histologic complexity can be displayed best on T2-weighted images; whereas the areas of abundant fibrous tissue appear hypointense, those of abundant myxoid stroma appear hyperintense. 3,21 Spontaneous hemorrhage is not infrequent. It is occasionally accompanied by fluid-fluid levels, and is seen as areas of time-dependent varying signal intensity on MR images.…”

“…3,18,22 On MR images, MFH is typically seen as a mass that is isointense to muscle on T1-weighted images and heterogeneously hyperintense on T2-weighted images. 3,18,[21][22][23] MR images often show heterogeneous signal intensity on all pulse sequences, reflecting the complex histologic components of the tumor. This histologic complexity can be displayed best on T2-weighted images; whereas the areas of abundant fibrous tissue appear hypointense, those of abundant myxoid stroma appear hyperintense.…”

“…The reported CT and MR imaging features of MFH have also been nonspecific. 3,18,[21][22][23] On CT scans, MFH is usually seen as a large lobulated soft-tissue mass, which is isoattenuated to muscle. Calcification or ossification can be detected in 5%-20%.…”

“…When compared to CT in 14 patients, MRI better defined the extent of the MFH, its relationship to surrounding tissues and vessels, and best differentiated residual or recurrent disease from postoperative changes when examined at least 3 mo after surgery. There was no significant difference in signal intensity of 12 preoperative and 13 recurrent neoplasms [27] . Tateishi et al have described the manner in which that primary MFH has a high signal intensity on T2-weighted MR images and non-homogeneous isosignal intensity compared with the surrounding muscle [28] .…”

“…Mahajan and colleagues have retrospectively reviewed the MRI changes in 39 patients with MFH, however, none of these originated from the pancreas [27] . This study concluded that MRI sensitivity and specificity for detecting a neoplasm were 96% and 83%, respectively, but the signal changes were non-specific for MFH.…”

Primary malignant fibrous histiocytoma (MFH) of the pancreas is rare and a distinct clinical entity. We report a case of recurrence of pancreatic MFH with computed tomography (CT) and magnetic resonance imaging (MRI) findings. A 67-year-old man presented with a history of decreased body weight over the past 6 mo. Abdominal CT revealed a large, multilocular cystic mass in the head of the pancreas with obvious atrophy in the body and tail of the pancreas. After 6 mo postoperatively, MRI demonstrated a recurrent large mass in the primary area of the head of the pancreas. The lesion was heterogeneous, hypointense to the liver on T1-weighted imaging, and heterogeneously hyperintense to the liver with a hypointense area in the central part of the tumor on fat-saturated T2-weighted imaging. Contrastenhanced T1-weighted imaging demonstrated a large multilocular cystic mass with a cystic wall, fibrous septa and enhancement of solid components. To the best of our knowledge, this is the first report on recurrence of primary MFH of the pancreas, and the first with MRI findings.

The objective of this review is to highlight the major imaging characteristics of the main soft-tissue sarcoma histotypes observed in the group "Sarcomi" of the Istituto Oncologico Veneto in the last 5 years. A literature review was performed using PubMed and textbooks. Radiological imaging can guide the diagnosis for the subset of lesions that have typical clinical and imaging features. Soft-tissue tumors are common in clinical practice and a systematic clinical and imaging approach may guide the diagnosis.
