Radiographics. Immediate subpleural sparing, when present is considered very specific for NSIP. Bronchoalveolar lavage (BAL) has been crucial in elucidating the immune effector cells involved in the inflammatory processes in idiopathic interstitial pneumonias 1. 13. Idiopathic interstitial pneumonias comprise usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), desquamative interstitial pneumonia (DIP), respiratory bronchiolitis–associated interstitial lung disease (RB-ILD), cryptogenic organizing pneumonia (COP), acute interstitial pneumonia (AIP), and lymphoid … A usual interstitial pneumonia (UIP) pattern on chest CT scans is highly suggestive of UIP pathologic findings; the most common cause of UIP is idiopathic pulmonary fibrosis (IPF) [1–5].Under current guidelines, a UIP pattern on CT images is specific for IPF after a thorough clinical and serologic workup has excluded other causes of … There is a broad overlap in ages for the two diseases. Kligerman SJ, Groshong S, Brown KK et-al. Bouros et al. Imaging features can overlap between cellular and fibrotic types as well as usual interstitial pneumonitis (UIP) in as high as 30% of patients. Radiographics. In a heterogeneous group of subjects with CTD, no significant difference in survival was noted between patients with CTD-related NSIP and UIP . Correct and early diagnosis has a significant impact on patien… 10. NSIP accounts for 14–35% of biopsies performed for chronic interstitial pneumonia. AJR Am J Roentgenol. Lynch DA. The presence of macroscopic honeycombing is almost diagnostic for UIP. Mycophenolate mofetil improves lung function in connective tissue disease-associated interstitial lung disease. Flaherty KR, Thwaite EL, Kazerooni EA, et al. Sverzellati N, Wells AU, Tomassetti S et-al. NSIP; Diagnostic Criteria. The key differential is a usual interstitial pneumonitis (UIP) pattern, with which there can be some overlap in imaging features 3. Hartman TE, Swensen SJ, Hansell DM et-al. UIP, indeterminate, probable NSIP, or definite NSIP. The features which favor the diagnosis of NSIP over UIP are symmetrical bilateral ground-glass opacities with fine reticulations and sparing of the immediate subpleural space. Biopsy-proved idiopathic pulmonary fibrosis: spectrum of nondiagnostic thin-section CT diagnoses. Classification and natural history of the idiopathic interstitial pneumonias. 16. High-resolution computed tomography features of nonspecific interstitial pneumonia and usual interstitial pneumonia. In some cases, cough may be more prominent in IPF but this is not reliable. Overall prevalence is higher in women due to high association with collagen vascular diseases, but the prevalence of idiopathic NSIP is similar in both genders. 2001;221 (3): 583-4. Kim DS, Collard HR, King TE. Nonspecific interstitial pneumonia with fibrosis: high-resolution CT and pathologic findings. Linking to any other page or site is at your own risk. Poletti V, Romagnoli M, Piciucchi S et-al. Radiographics. Unable to process the form. 2003;123 (4): 1096-103. At the other end of the spectrum, idiopathic cellular NSIP and DIP have a survival rate of nearly 100% (14,15). The presence of the following features, although they can be seen in NSIP, should make us think about other differentials: In general, non-specific interstitial pneumonia (NSIP) carries a much more favorable prognosis than a UIP-type pattern with 90% 5-year survival rate for cellular and ~60% (range 45-90%) 5-year survival in the fibrotic subtype. 2000;217 (3): 701-5.
