Chest calcifications beyond the lung parenchyma-A review

Area of Science:

• Radiology
• Medical Imaging
• Pathology

Background:

• Thoracic calcifications are frequently observed in chest radiographs and CT scans.
• These calcifications can be incidental findings or indicators of underlying diseases.

Purpose of the Study:

• To review different types of calcified lesions in the chest, specifically those outside the lung parenchyma.
• To provide a location-based approach for differential diagnosis of thoracic calcifications.

Main Methods:

• Review of radiologic literature and imaging findings.
• Categorization of calcifications based on their location within the chest.
• Discussion of diagnostic pearls and clinical significance.

Main Results:

• Identification of various calcified lesions in the chest, including pleural, mediastinal, and chest wall calcifications.
• Emphasis on the diagnostic value of calcifications in identifying sequelae of previous diseases or active conditions.

Conclusions:

• Thoracic calcifications are common and provide valuable diagnostic information.
• A systematic, location-based approach aids in differentiating benign from clinically significant calcifications.
