fibrosseous pseudotumour of the digit (FOPD)

Fibrosseous

pseudotumour of the digit (FOPD): non-calcified radiologic appearance. Axial and sagittal, soft tissue (a,b); coronal, bone window (c): 25 mm well-defined soft tissue mass, slightly hyperdense (~34 HU), hypodense to muscles. No air bubbles or calcifications inside. No bone abnormalities (arrowheads).

pseudotumour of the digit (FOPD): non-calcified radiologic appearance. T1w (a,d,e - FS: a,e): 30 mm iso/hypointense nodule. STIR (b,f): hyperintense, thin-walled. Gd+ (c,g): strong \"rim-like\" enhancement (arrowheads, g). Tendon displacement (arrows, a,b,c). Normal bone.

pseudotumour of the digit (FOPD): non-calcified radiologic appearance. (a-c). A swelling is recognizable on the radial aspect of the fourth finger (arrows) without evidence of bone abnormalities. Note the absence of calcifications inside the swelling.
