Subcutaneous panniculitis-like T-cell lymphoma: US and CT findings in three patients.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare disorder. We examined two females and one male with multiple soft-tissue masses in the abdominal wall. One of these three patients also had soft-tissue masses in the right thigh and right buttock. The histologic diagnosis was revealed as SPTCL in all three cases. The ultrasound (US) findings in two of these cases were diffuse, ill-defined hyperechoic areas with a linear vascular signal. The findings of the abdominal and pelvic computed tomography (CT) scanning with contrast enhancement were multiple enhancing nodules with an infiltrative pattern of peripheral subcutaneous fat layer in all three cases. We report US and CT findings of SPTCL in these three patients.
