High resolution computed tomography (HRCT) of the lungs with interstitial changes during the treatment. Fig. 1a: HRCT with interstitial lung disease with bibasilar predominance of peribronchial consolidations suspect of organizing pneumonia (OP) and non-specific interstitial pneumonia (NSIP);Fig. 1b: CT scan with progression of the interstitial findings;Fig. 1c: Significant regression of the interstitial changes after methylprednisolone;Fig. 1d: Basal reticulation, ground-glass opacities and perilobular consolidations consistent with OP and NSIP;Fig. 1e: HRCT with significant regression of the interstitial findings.

A CT angiography showed progression of the interstitial changes without signs of pulmonary embolism (Fig. 1b). The symptoms improved after the first course of pulse therapy with normalization of the inflammatory parameters and significant regression in the interstitial features on HRCT (Fig. 1c).
