A. Pre-treatment Chest CT shows massive opacities in the right lung lobes, geographic distribution of ground-glass opacities and associated thickening of the interlobular septa mainly in middle and lower lobes, consolidation mainly in low lobe. B. Bronchoscopy showed that the wall of the air tube was edematous with a small amount of pus.C.One year after Steroid treatment, Chest CT Shows dramatic Improvement. D. Lung puncture biopsy specimen of right lung nodular area showed empty spaces and vacuoles correspond to lipid dissolved. Hematoxylin- and eosin-stained slide.

After admission, a chest CT was performed which showed multiple dense consolidation located in right lung, predominantly in low lobe (Fig. 1A). Through bronchoscopy, we found that the wall of the air tube was edematous with a small amount of pus (Fig. 1B), the lavage was clear. Lung biopsy showed lipid granulomas with fat-laden macrophages (Fig. 1D), consistent with the pathological features of lipoid pneumonia. Chest CT showed dramatic improvement 1 year after steroid therapy. (Fig. 1C).

A Chest CT showed necrotic consolidations with air bronchograms in right middle lobe (lung window). B Six months after treatment, chest CT shows most of lung opacity has been resolved. C Edematous change was observed in the right middle and lower lobe with a lot of grayish purulent secretions. D Photomicrograph of lung biopsy with hematoxylin-eosin stain showed necrosis, granuloma.

Chest CT scan performed at our hospital showed necrotic consolidation, ground glass opacity (GGO) and bronchial wall thickening in the right middle lobe (Fig. 2A). Edematous changes was observed in the right middle and lower lobe with a lot of grayish purulent secretions were observed under bronchoscopy (Fig. 2B). The pathological examinations reflected the acute inflammation and granuloma formation (Fig. 2D). Oral systemic steroid was prescribed for 6 weeks with gradual tapering off. 6 months after the treatment, chest CT showed dramatic Improvement (Fig. 2C), no recurrence has been observed in the patient so far.
