We studied the relationship between the histopathology obtained by trans-bronchial lung biopsy (TBLB), and spirometric indices in 28 patients of pulmonary sarcoidosis in whom the diagnosis was confirmed. There was a rough correlation between FVC and the histologic granuloma load, interstitial inflammation and the overall histopathological score. Radiological features did not correlate with either spirometry or histopathology.
