Pulmonary Silicosis Presents with Pleural Effusion.

Area of Science:

• Pulmonary Medicine
• Occupational Health
• Radiology

Background:

• Silica and silicate mineral dust inhalation lead to lung and pleural histopathological changes.
• Common findings include silicotic nodules, fibrosis, and pleural thickening.
• Pleural effusion is an exceptionally rare complication of silicosis.

Purpose of the Study:

• To report an extremely rare case of silicosis presenting with pleural effusion.
• To contribute to the limited medical literature on this specific presentation of silicosis.

Main Methods:

• Case study of a 77-year-old male with extensive occupational silica exposure.
• Clinical presentation included exertional shortness of breath.
• Diagnostic imaging included chest X-ray and chest CT.

Main Results:

• Chest X-ray revealed right lung infiltrate and bilateral pleural thickening and effusion.
• Chest CT confirmed moderate bilateral pleural effusion and thickening with intrapulmonary nodules.
• Extensive workup led to a diagnosis of silicosis.

Conclusions:

• This case underscores the possibility of pleural effusion as a presentation of silicosis, despite its rarity.
• The findings emphasize the importance of considering silicosis in patients with relevant occupational history and pleural effusion.
• Further investigation into the mechanisms of silicosis-induced pleural effusion is warranted.
