Summary
Assessing lymphoma treatment response typically involves cross-sectional imaging like CT and MRI. This review focuses on interpreting residual masses, which can have variable appearances, to aid diagnosis.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Lymphoma treatment response is conventionally assessed using cross-sectional imaging techniques.
- Standardized definitions for response and expected changes on CT and MRI in the chest and abdomen are established.
Purpose of the Study:
- To review the variable appearances of residual lymphoma masses after treatment.
- To identify key features on imaging that assist in the diagnosis of residual masses.
Main Methods:
- Review of cross-sectional imaging (CT and MRI) findings in lymphoma patients post-treatment.
- Analysis of documented cases with residual masses to identify characteristic features.
Main Results:
- Established definitions for response and changes on CT/MRI are well-recognized.
- Residual masses post-lymphoma treatment exhibit more variable imaging appearances.
Conclusions:
- Interpreting residual masses in lymphoma requires careful consideration of variable imaging features.
- This review aims to provide guidance on diagnosing residual masses based on their CT and MRI appearances.
