Diagnosis With Brief Discussion

Diagnosis
Airway Involvement in Sarcoidosis
Radiologic Findings
Chest CT scan show predominant peribronchovascular and subpleural nodules in both lungs. Nodularity are also seen on lower trachea and both main bronchi. Elarged lymph nodes are seen in mediastinuma and hilar areas.
Brief Review
Sarcoidosis is a multisystemic granulomatous disease of unknown cause that is characterized by the formation of noncaseous epithelioid cell granulomas. Sarcoidosis primarily affects the lung and lymphatic systems.Sarcoidosis involves the respiratory system in > 90% of cases, usually the hilar and mediastinal nodes, and, less frequently, the lung tissue. Airway involvement, as judged by clinical features, physiologic testing, imaging techniques, bronchoscopy, and airway mucosal biopsy, has been observed in nearly two-thirds of patients with sarcoidosis.The initial morphologic abnormality is the airway inflammation manifested by mucosal edema, erythema, and the formation of granulomas. As the airway disease progresses, the mucosa may demonstrate granularity, nodularity, cobblestoning, and friability. Sarcoid nodules in the bronchi may cause postobstructive atelectasis, airway luminal narrowing, and distortion. As the fibrotic phase sets in, mucosal thinning, pallor, and scarring may lead to airway luminal narrowing and stenosis. CT scans may demonstrate bronchial distortion, angulation, and displacement. Decreased airway luminal diameter caused by endobronchial granulomas and evidence of bronchial mural thickening may be seen. Extrinsic compression of the airways by the enlarged lymph nodes may be depicted. However, CT scans can be misleading and provide false-positive results, incorrectly predicting the presence of focal bronchial abnormalities in up to 15% of patients.The main role of chest CT scanning is to evaluate the thoracic lymph nodes and pulmonary parenchymal process. Its role in assessing airways is limited and is rarely indicated for serial follow-up of the airway disease.
