Imaging Features of Superficial and Deep Fibromatoses in the Adult Population
Figure 1
Palmar Fibromatosis. Lateral radiograph (a) of the right hand 5th finger in a 48-year-old man shows a flexion (Dupuytren) contracture of the proximal interphalangeal (PIP) joint. MR images of a 73-year-old man with pathologically proven palmar fibromatosis. (b) Axial T1-weighted (TR 500/TE 21) and (c) axial proton-density-weighted (TR 1500/TE 35) fat suppressed images of the hand at the level of the metacarpal bones show nodular areas of low-signal intensity in the volar subcutaneous fat (arrows) located superficial to the flexor tendons of the fourth and fifth fingers. Increased signal surrounds the nodules (curved arrow) on fluid sensitive sequence. (d) Axial T1-weighted (TR 500/TE 21) fat-suppressed image after administration of gadolinium contrast demonstrates moderate and diffuse enhancement (curved arrow) surrounding the nodules.
