    Angioimmunoblastic T-cell lymphoma (AITL) is a rare peripheral T-cell lymphoma with heterogeneous clinical presentations.

  • 2

    A 65-year-old female exhibited FDG-negative superficial lymph nodes on PET/CT, complicating her diagnosis of AITL.

  • 3

    Initial biopsies of hypermetabolic deep lymph nodes were non-diagnostic, delaying the definitive diagnosis of AITL.

  • 4

    The case highlights the potential for false-negative PET/CT findings in AITL, necessitating a multimodal diagnostic approach.

  • 5

    Integration of clinical, laboratory, and histopathologic data is essential to avoid diagnostic delays in AITL.
