From the Guidelines
Biapical pleural thickening is typically a benign condition that requires no specific treatment, but clinical correlation and follow-up imaging are necessary to ensure stability and rule out underlying causes such as asbestosis or previous infections. When evaluating biapical pleural thickening, it is essential to consider the patient's symptoms, history of lung infections, occupational exposures, and smoking status. According to a study published in the American Journal of Respiratory and Critical Care Medicine 1, pleural plaques, which can be associated with biapical pleural thickening, are often seen in individuals with a history of asbestos exposure. Key points to consider in the management of biapical pleural thickening include:
- Clinical correlation to evaluate for symptoms like cough, shortness of breath, or chest pain
- Investigation of the patient's history of lung infections, occupational exposures, or smoking
- Follow-up imaging every 6-12 months to ensure no progression
- Consideration of underlying causes such as previous tuberculosis, fungal infections, asbestosis, or other occupational lung diseases It is crucial to note that while biapical pleural thickening itself may not require treatment, underlying conditions such as asbestosis or previous infections may need to be addressed. A study published in the same journal 1 found that the presence of pleural plaques is associated with a greater risk of mesothelioma and lung cancer, highlighting the importance of careful evaluation and monitoring. In asymptomatic patients with stable findings, periodic monitoring with chest imaging may be recommended initially to ensure no progression. However, if symptoms or underlying conditions are present, more frequent monitoring or specific treatment may be necessary.
From the Research
Biapical Pleural Thickening
- Biapical pleural thickening is not explicitly mentioned in the provided studies, however, pleural thickening is discussed in the context of asbestos exposure and other conditions.
- According to 2, pleural plaques were always bilateral and less than 1 cm thick, with calcifications in 80% of the cases, and were found to be a specific sign of asbestos exposure.
- The study 3 found that pleural thickening was more common in males, current smokers or ex-smokers, and increased with age, but did not specifically discuss biapical pleural thickening.
- The radiographic evaluation of asbestos-related chest disorders, including pleural plaques and diffuse pleural thickening, is discussed in 4, but biapical pleural thickening is not mentioned.
Pleural Thickening Characteristics
- Pleural thickening can be characterized by its location, thickness, and margins, as well as the presence of calcifications or effusion 2.
- The study 3 found that pleural thickening was often associated with a pulmonary apical cap, particularly on the right side.
- The characteristics of pleural thickening can be used to differentiate between various conditions, such as asbestos-related disease, mesothelioma, and pleural metastatic disease 2, 4.
Asbestos Exposure and Pleural Thickening
- Asbestos exposure is a known cause of pleural thickening, and the presence of pleural plaques is a specific sign of asbestos exposure 2, 4.
- The study 2 found that all patients with pleural plaques had a history of direct or indirect asbestos exposure, except one with malignant pleural mesothelioma.
- The relationship between asbestos exposure and pleural thickening is discussed in 4, including the epidemiological features of pleural and pulmonary parenchymal disorders related to asbestos exposure.
