MR Findings of Subcutaneous Panniculitis-like T-Cell Lymphoma: A Case Report

described as a pathologic entity by the World Health Organization classification system for lymphoid neoplasms, and PTCL represents a relatively small proportion of all the lymphomas (1). It has a lower prevalence in Western countries than else where; it makes up approximately 10-15% of all non-Hodgkin’s lymphomas in Europe (2), versus 25% in Korea (3). Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is an unusual type of PTCL. Clinically, it is often confused with inflammatory panniculitis. The medical literature contains little information on the diagnostic images of SPTCL, and especially the MR images. To the best of our knowledge, there are only a few reports on PTCL in the English-language medical literature (4, 5) We report here on the MR findings in a case of SPTCL that presented with a popliteal mass.
