Figure 2. (a) T₁ weighted axial MR image of abdomen showing heterogeneous signal with ill-defined margin in subcutaneous fat of right anterior abdominal wall. It is of predominantly intermediate signal intensity and isointense to adjacent muscle. Areas of signal intensity identical to subcutaneous fat were demonstrated (arrow). Small round hypointense foci are also detected in the periphery part of the lesion (open arrows). (b) Fat-suppressed T₂ weighted axial MR images of abdomen showing heterogeneous predominantly low signal intensity in subcutaneous layer of right anterior abdominal wall. High signal changes are present in right external oblique muscle (arrow) which are contiguous with the overlying subcutaneous lesion. Small round peripheral markedly hypointense foci are also demonstrated (open arrows) corresponding to the findings on T₁ weighted image.
