Imaging Features of Superficial and Deep Fibromatoses in the Adult Population
Figure 2
Plantar fibromatosis: a 54-year-old male who presents with left foot pain for one year. A longitudinal ultrasound color Doppler image (a) demonstrates a soft tissue mass with heterogeneous echotexture and internal color Doppler flow (arrow). (b) Sagittal T1-weighted (TR539.4/TE15) fat saturation postcontrast sequence demonstrates a fusiform, enhancing lesion with linear extension (fascial tail sign) along the plantar aponeurosis (arrow). Short axis MR images ((c)–(e)) demonstrate a well-defined mass (arrows) in the medial aspect of the plantar aponeurosis (c) Short axis T1-weighted (TR568/TE15) sequence reveals lesion signal intensity similar to skeletal muscle. There is heterogeneity with several foci of low signal (curved arrows) within the lesion. (d) Short axis T2-weighted (TR2693/TE60) with fat suppression reveals intermediate-to-high heterogeneous signal (arrow) and (e) T1-weighted (TR638.7/TE15) postcontrast fat saturation sequences demonstrate marked heterogeneous enhancement (arrow). Curved arrows indicate band-like areas of higher collagen content and low cellularity. Note the lower T1 and T2 signal intensity and lack of enhancement in these foci.
