A rare muscle lymphoma was diagnosed using Gallium-67 scans in a man with systemic symptoms. Despite initial treatment, the diffuse large B-cell lymphoma recurred, highlighting the need for advanced imaging and potential links to Klinefelter syndrome.

Area of Science:

  • Oncology
  • Diagnostic Imaging
  • Genetics

Background:

  • Systemic symptoms can present diagnostic challenges, sometimes masking rare underlying conditions.
  • Elevated Interleukin-6 (IL-6) levels and acute-phase responses indicate significant inflammation but lack specificity.
  • Extranodal lymphomas, particularly those affecting muscle tissue, are uncommon and require specific diagnostic approaches.

Observation:

  • A whole-body Gallium-67 scan was critical, identifying high uptake in paraspinal and psoas muscles.
  • Surgical biopsy confirmed diffuse, large B-cell non-Hodgkin lymphoma of muscle (stage IE), an extranodal lymphoma.

Findings:

  • The patient initially responded to cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) therapy, achieving remission.
  • Recurrent multifocal disease was detected via a repeat Gallium-67 scan, requiring salvage chemotherapy.

  • A 47,XXY karyotype, indicative of Klinefelter syndrome, was identified and potentially linked to the lymphoma.

    • Implications:

    • Gallium-67 scintigraphy is valuable for diagnosing rare extranodal lymphomas.
    • Extranodal non-Hodgkin lymphoma can present with non-specific systemic symptoms.
    • The association between Klinefelter syndrome and non-Hodgkin lymphoma warrants further investigation.
