Summary
Thoracic lymphomas commonly affect mediastinal lymph nodes and can involve various chest structures with diverse imaging findings. Computed tomography (CT) and fluorodeoxyglucose-positron emission tomography (FDG PET) are key for diagnosis and management.
Area of Science:
- Thoracic oncology
- Diagnostic imaging
- Hematologic malignancies
Background:
- Thoracic lymphomas frequently involve mediastinal lymph nodes, particularly in the anterior mediastinum and paratracheal regions.
- These lymphomas can also affect the lungs, thymus, pleura, pericardium, chest wall, and breast, presenting with varied radiologic manifestations.
- Primary pulmonary lymphomas, such as BALT lymphoma and large B-cell lymphoma, exhibit diverse imaging features like nodules and consolidation.
Purpose of the Study:
- To summarize the radiologic manifestations of thoracic lymphomas.
- To highlight the roles of CT and FDG PET in evaluating and managing these conditions.
Main Methods:
- Review of radiologic findings in thoracic lymphomas.
- Discussion of the utility of CT and FDG PET imaging.
Main Results:
- Thoracic lymphomas demonstrate diverse imaging features across multiple thoracic structures.
- CT is the primary imaging modality for thoracic lymphoma evaluation.
- FDG PET is crucial for clinical management, including staging and response assessment.
Conclusions:
- Thoracic lymphomas present with a wide spectrum of radiologic appearances.
- Integrated use of CT and FDG PET is essential for comprehensive evaluation and management of thoracic lymphomas.
