Mass within distal forearm Within the superficial ulnar soft tissues of the distal forearm approximately 3 cm from the distal radius/ulna is a well-circumscribed, T1 isointense/T2 hyperintense solid mass which measures approximately 1.3 x 1.2 x 1.4 cm in the greatest transaxial and craniocaudal dimensions. There are some areas of low signal internally on the T2 sequences. The mass enhances relatively homogeneous with scattered areas of low signal on postcontrast sequences as well. The mass is in close proximity to the basilic vein which appears to run through or over the lesion.No additional soft tissue masses are identified. The osseous structures of the forearm are normal.
Superficial soft tissue mass within the volar the cutaneous tissues of the distal forearm further described above. The imaging findings are nonspecific in nature with some differentials including a vascular lesion or peripheral nerve sheath tumor.
