Purpose : To evaluate the MR findings of extra-abdominal fibromatosis and the role of
MRI in primary diagnosis
Materials and Methods : Fifteen cases in of histologically proven extra-abdominal
fibromatosis in 13 patients were retrospectively reviewed. T1-weighted and T2-weighted
images were obtained in axial, coronal and sagittal planes, Gd-enhancement was
performed in 14 cases, and enhancement studies in two. All lesions were evaluated for
mass shape and margin definition.
Results : Among the 15 cases, tumors of the buttock accounted for five, and tumor of
thigh for two. In eight cases tumors were intermuscular and in six cases were
intramuscular. In ten cases(67%) the mass extended along the long axis of the body and
in 14 of 15 cases (93%) focal infiltration of adjacent structures was visible. The signal
intensity of the lesion was in all cases inhomogeneous on both T1 and T2 weighted
images. As seen on Gd-DTPA enhanced scans, the masses were inhomogeneously
enhanced. In all cases MRI revealed star-shaped linear strands or a band low signal
area in the mass. These features were not enhanced and were arranged along the long
axis of the mass.
Conclusion : MR findings of extra-abdominal fibromatosis were relatively characteristic
and helpful primary diagnosis of condition.
