C-reactive protein (CRP), but negative auto-immune antibodies, normal low density and high density lipoproteins, and normal IgE (Table 1). Computed tomography of the chest revealed consolidation with ground-glass opacity (GGO) in the posterior segment of the right upper lobe and patchy GGO in segment 6, with slight pleural effusions (Fig. 1).

We found that macrophages were phagocytosing lipids (Fig. 2).
Response to corticosteroid treatment. Body temperature and CRP levels were measured daily for 9 days of corticosteroid treatment. Body temperature was stable in the normal range on day 10. Chest X-ray imaging was performed 1 month before onset, 1 month after onset, and on days 1 and 9 of corticosteroid treatment. BTmax, temperature maximum; CRP, C-reactive protein; MEP, methylprednisolone; PSL, prednisolone.

Her fever improved (36.3  C) and oxygen saturation (ambient air) was 97% by hospital day 3; the chest X-ray image showed an improvement in the shadow of the upper right lung field (Fig. 3).
