6-year-old girl with history of right forearm desmoid tumor. Follow-up examination. Again seen is a heterogeneous mass on the radial aspect of the forearm. Thismass demonstrates predominately low T1 signal intensity, with heterogeneous T2 signalintensity. There is minimal enhancement.The superficial portion of the mass is located on the radial aspect of the forearm andinvolves the superficial forearm extensors, including the brachioradialis and extensorcarpi radialis longus. This superficial portion of the tumor (series 1101, image 26)measures 4.5 x 2.6 x 7.1 cm (previously 4.1 x 2.4 x 6.8 cm).The deep portion of the mass extends into the interosseous region and partially encasesthe radius. This deep portion of the mass (series 2001, image 18) measures 2.0 x 1.1 cmon axial images (previously 1.9 x 1.4 cm).
Minimal increase in size of right forearm desmoid tumor.
