Clinical Report: False-Negative Findings in PET/CT for Angioimmunoblastic T-Cell Lymphoma
Background
Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive form of peripheral T-cell lymphoma, accounting for 1-2% of non-Hodgkin lymphomas. Its clinical presentation can be complex, often leading to misdiagnosis and delays in treatment. The role of PET/CT in staging and response assessment is critical, yet false-negative results can occur, complicating the diagnostic process.
Data Highlights
No numerical data provided in the article.
Key Findings
AITL can present with false-negative PET/CT findings, particularly in superficial lymph nodes.
The patient initially exhibited hypermetabolic activity in deep mediastinal and hilar nodes while superficial nodes were FDG-negative.
Initial biopsies of FDG-avid sites were non-diagnostic, delaying the definitive diagnosis.
Multisystem involvement and severe anemia were significant clinical features in this case.
Clinical Implications
Clinicians should be aware of the potential for false-negative PET/CT results in AITL.
Conclusion
This case highlights the occurrence of false-negative PET/CT results in AITL.
