Plain-English summary
An 8-year-old male neutered Domestic Long Hair cat was brought to the vet for a swollen neck, which was thought to be an enlarged lymph node. A special scan called PET/CT revealed that the cat had lymphoma affecting multiple organs. Instead of surgery, the vet recommended chemotherapy, and the cat initially responded well, achieving a temporary partial remission. Unfortunately, after two months, the cat's condition worsened, and he was euthanized due to a relapse and poor quality of life.

Abstract
An 8-year-old male neutered Domestic Long Hair cat was presented for a cervical swelling that was suspected to be an enlarged left retropharyngeal lymph node. In the absence of other lymphadenopathy, this was initially suspected to be Hodgkin's-like lymphoma. A positron emission tomography-computed tomography (PET/CT) scan was performed using 2-deoxy-2-[F]-fluorodeoxyglucose (F-FDG) to assess for evidence of disease in other locations to guide treatment. Multifocal increased radiopharmaceutical uptake was identified, indicating disease in multiple organs. High-grade lymphoma was confirmed on tissue biopsy. As such, systemic cytotoxic chemotherapy was recommended instead of lymph node extirpation surgery. The cat received a modified CHOP chemotherapy protocol and attained a temporary partial remission. After 2 months of treatment, the cat stopped responding to chemotherapy and was eventually euthanized due to a relapse of disease and decreased quality of life. This case describes the utility of PET/CT to guide treatment in a cat with a presentation consistent with Hodgkin's-like lymphoma.
