PURPOSE: To describe the computed tomographic (CT) findings in patients with
nonspecific interstitial pneumonia (NSIP) and to compare these with the CT
findings of other chronic infiltrative lung diseases. MATERIALS AND METHODS:
Findings in 50 patients with biopsy-proved NSIP and a CT scan were reviewed by
two thoracic radiologists in consensus. After the findings were described, the
observers judged whether the findings were compatible with previously published
descriptions of NSIP or whether the findings would support the diagnosis of a
different chronic infiltrative lung disease. RESULTS: Eleven (22%) of the 50
patients had CT findings that were compatible with previous descriptions of NSIP.
Sixteen (32%) patients had CT findings that were more compatible with usual
interstitial pneumonia. The other 23 (46%) patients had findings that were
nondiagnostic or most compatible with the diagnosis of another chronic
infiltrative lung disease. CONCLUSION: Contrary to previously published
articles, there are a wide variety of CT findings in cases of NSIP.
