Figure 5:

(A) Axial contrast-enhanced T1-weighted fat-suppressed MRI scan at baseline shows an enhancing desmoid fibromatosis deep in the lateral proximal thigh that measured up to 64 mm in maximum diameter (arrow). (B) At follow-up 14 months later, the desmoid fibromatosis shows increase in diameter to 81 mm (arrow), a 27% increase from baseline, constituting progressive disease. Note that while the anterior tumor component contains characteristic bands of collagen, the posterior component remains avidly enhancing and has increased in width.
