Imaging Evaluation of Malignant Chest Wall Neoplasms

Area of Science:

• Radiology
• Oncology
• Thoracic Imaging

Background:

• Chest wall neoplasms are rare, accounting for about 5% of thoracic malignancies.
• These tumors can be benign or malignant, originating from bone or soft tissue, or invading from other sites.
• Over half of chest wall neoplasms are malignant.

Purpose of the Study:

• To review the role of imaging in evaluating chest wall neoplasms.
• To highlight the strengths and limitations of various imaging modalities.
• To emphasize the importance of recognizing imaging features for diagnosis and treatment planning.

Main Methods:

• Review of multidetector computed tomography (CT) and magnetic resonance (MR) imaging.
• Discussion of fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT and ultrasonography.
• Emphasis on differentiating malignant from benign lesions.

Main Results:

• Multidetector CT excels in visualizing bone, muscle, and vasculature.
• MR imaging offers superior soft-tissue contrast and delineation of disease extent.
• FDG PET/CT is primarily used for staging, treatment response, and recurrence detection.

Conclusions:

• Radiologists must identify key CT and MR imaging features to differentiate benign from malignant chest wall lesions.
• Accurate imaging interpretation is vital for suggesting specific tumor types and guiding patient management.
• While CT and MR are primary tools, ultrasonography aids in superficial lesions and biopsy guidance.
