Relapsed Breast Implant–Associated Anaplastic Large-Cell Lymphoma Presenting as Refractory Fluid Collections With Low Uptake on FDG PET/CT Scan

Breast implant-associated anaplastic large-cell lymphoma is a rare type of non-Hodgkin lymphoma that occurs years after placement of textured surface breast implants. Patients typically present after the development of pain, a palpable mass, or swelling. We present a case of a 45-year-old woman with recurrent breast implant-associated anaplastic large-cell lymphoma presenting as refractory fluid collections, and the unusual finding of low uptake on FDG PET/CT scan despite being confirmed by cytology.
