“…MFH mainly involves extremities followed by the retroperitoneum. Uncommon locations include the head and neck region, dura mater, brain, lung, heart, aorta, pancreas, liver, spleen, breast, intestine and mesentery [6][7][8][9][10] .…”

“…During a MEDLINE search we found only 14 reported cases in the English literature including ours. On CT, MFH typically presents as a poorly marginated or well circumscribed soft tissue mass, with hypodense areas due to necrosis [9,25] . Eccentrically located lumpy and ring-like calcifications due to osteoid and chondroid metaplasia have been reported on CT in 16% of abdominal MFHs [6] .…”

AIM:To study computed tomography (CT) �eatures of abdominal malignant fibrous histiocytoma (MFH) in various rare locations. METHODS:We retroprospectively identi�ied cases o� �FH involving the abdominal cavity. �articular attention was paid to details regarding imaging �eatures and histological types. RESULTS:The study population consisted o� seven men and one woman, with a mean age o� 52.5 years. Seven patients had some physical symptoms, while one was incidentally detected. The sites o� origin were liver (n = 3), greater omentum (n = 1), superior mesentery (n = 1), ileum (n = 1), right psoas muscle (n = 1) and right kidney (n = 1). With the exception o� the ileum lesion, all were o� huge size. The contour o� the lesions was more or less clear. Foci o� necrosis were present in six lesions (n = 6). On plain CT scan, all lesions were hypo to iso dense. The lesion in the greater omentum was cystic. One lesion (n = 1) showed signi�icant enhancement and the cystic lesion showed mild peripheral enhancement. An abundance o� blood vessels surrounding the mass was seen in two lesions (n = 2) and both were o� the in�lammatory variety. �athological examination revealed stori�orm-pleomorphic variety (n = 4), inflammatory variety (n = 3) and myxoid variety (n = 1). Two of the patients with inflammatory MFH had a clinical presentation o� �ever and one was a�ebrile, however, blood investigations in all three showed leukocytosis.CONCLUSION: �rimary �FHs o� the abdominal viscera and gastrointestinal tract are generally huge so�t tissue masses containing areas o� low attenuation and mild to moderate contrast enhancement.

“…Clinically and radiographically, MFH arising from the kidney or renal capsule cannot be differentiated from other renal or retroperitoneal neoplasms such as renal cell carcinoma, infl ammatory pseudotumor and xanthogranulomatous pyelonephritis. It has been reported that ring-like or round calcifi cations around the tumor could be detected in 16% of abdominal MFH especially in the storiform-pleomorphic subtype [5] .…”

“…Liu et al have described a predominant cystic MFH of the pancreas of the myxoid variety [10] , but other reports and our case suggest that not all cystic degeneration of the tumor belongs to the myxoid pattern [11,12] . Ko et al have considered that abdominal MFH, especially the storiform-pleomorphic subtype, exhibits metaplastic calcifications on CT, and they showed a heterogeneously enhanced mass with a large necrotic area in the pancreatic body and tail, and eccentrically located ring calcification [26] . Akatsu et al did not, however, support this sign and concluded that calcification is not always helpful in differentiating pancreatic MFH from other pancreatic tumors [11] .…”

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.
