Magnetic resonance imaging of peripheral T-cell lymphoma.

We report magnetic resonance (MR) findings of two unusual cases of peripheral T-cell lymphoma, one initially presenting as a soft-tissue mass in the neck and the other in the foot. MR imaging provides better tissue contrast and lesion delineation than CT. However, MR signal characteristics cannot differentiate this lymphoma from other soft-tissue tumours. Although it is rare, peripheral T-cell lymphoma should be included in the differential diagnosis of a soft-tissue mass.
