(a,b) X-rays and CT scans of the patient before the treatment of HS. (a) Chest roentgenogram showed bilateral infiltrates and opacities in different lung lobes. (b) Chest CT scan showed interstitial lung disease. (c,d) X-rays and CT scans of the patient after the treatment of HS. (c) Chest roentgenogram showed that pulmonary infiltrates cleared. (d) Chest CT scan was normal. (e) Chest roentgenograms in regular follow-up visit showed no infiltrates and opacities.

Chest roentgenograms showed bilateral infiltrates and opacities in different lung lobes (Figure 1a). The CT scan showed interstitial lung disease (Figure 1b), and the oxyhemoglobin saturation (SpO2) could not be maintained without oxygen intake (the lowest SpO2 was 80%). Chest roentgenograms showed that pulmonary infiltrates cleared within 5 days (Figure 1c), and the CT scan was normal (Figure 1d). Chest roentgenograms showed neither infiltrates nor opacities (Figure 1e).
(a-c) Gastrointestinal endoscopic pictures and the pathological sections. (a) Gastroscopic pictures showed chronic superficial gastritis. (b) Enteroscopic pictures showed a hyperplasia in descending colon (arrow: hyperplasia). (c) The section of hyperplasia showed granulation tissue infiltrated mostly by acute and chronic inflammatory cells (arrow: eosinophils). (100x) (d-f) Gastrointestinal endoscopic pictures and the pathological sections in follow-up visit. (d) Gastroscopic pictures showed normal results. (e) Enteroscopic pictures showed inflammatory hyperplasia (arrow: hyperplasia). (f) The section of hyperplasia showed tissue infiltrated by inflammatory cells. (100x).

She was subjected to gastrointestinal endoscope, revealing chronic superficial gastritis (Figure 2a) and hyperplasia in the descending colon (Figure 2b). The examination showed granulation tissue infiltrated by acute and chronic inflammatory cells, including some eosinophils (at most three per high-power field) (Figure 2c). Besides this, the gastroscope showed normal results (Figure 2d), and enteroscope showed inflammatory hyperplasia (Figure 2e). The light microscopic examination of the biopsy showed tissue infiltration by inflammatory cells (Figure 2f).
