Given these physical, chemical, and mechanical traumas, the cell structures affected by the inhaled, nasal, and oral sprayed insulin can undergo changes such as metaplasia, in which cells change from their original mature, differentiated type into another cell type; dysplasia, in which the cell change (different form) is indicative of an early step towards transformation into a tumor (cancer; for example, leukoplakia of the oral cavity); or heteroplasia, the abnormal cell growth of existing cells as seen in blood vessels of hypertensives and in bronchiolar asthmatics.

The wide spectrum of radiologic findings described in RA can be categorized in 5 broad patterns: (1) reticular opacities with lobular distortion, intralobular lines, and traction bronchioloectasis (with or without honeycombing) that correlate with fibrotic ILD (usual interstitial pneumonia [UIP] or nonspecific interstitial pneumonia [NSIP]); (2) airway-associated abnormalities, such as fuzzy centrilobular nodules of ground-glass attenuation (follicular bronchiolitis) or bronchial and bronchiolar wall thickening with heterogeneous lung attenuation (Figure 1; constrictive bronchiolitis); (3) patchy, often peripheral, consolidation that correlates with organizing pneumonia (OP); (4) random parenchymal nodules (rheumatoid nodules); and (5) pleural effusions.
