Imaging of primary chest wall tumors with radiologic-pathologic correlation

Area of Science:

• Radiology
• Oncology
• Pathology

Background:

• Primary chest wall tumors are rare and can present diagnostic challenges due to nonspecific imaging features, especially for locally aggressive lesions.
• Unfamiliarity with these neoplasms can lead to diagnostic difficulties for radiologists.

Purpose of the Study:

• To outline a systematic approach for diagnosing primary chest wall tumors.
• To aid radiologists in differentiating between various types of bone and soft-tissue chest wall neoplasms.

Main Methods:

• Classification of primary chest wall tumors based on the 2002 World Health Organization guidelines.
• Utilizing patient age, clinical history, lesion location, and characteristic imaging findings to narrow differential diagnoses.
• Employing cross-sectional imaging to further refine diagnoses within tumor categories.

Main Results:

• A systematic approach aids in limiting the differential diagnosis of primary chest wall tumors.
• Specific imaging features like mineralization, fibrosis, hemosiderin deposits, and patterns such as the 'target sign' and 'fascicular sign' assist in diagnosis.
• Radiologists can achieve specific diagnoses for bone and soft-tissue tumors when typical findings are present.

Conclusions:

• A structured diagnostic strategy incorporating clinical and imaging data is crucial for managing primary chest wall tumors.
• Accurate diagnosis of these uncommon neoplasms is achievable with careful evaluation of characteristic imaging findings.
