Reversal of Heart and Respiratory Failure Following Accidental Exposure to Hydrogen Sulfide: Case Report

Figures

Figure 1. Chest-X ray serial imaging. (A) On admission, showing a predominant right sided heterogeneous lung infiltrate; (B) on the 7th in-hospital day revealing an aggravating lung injury; (C) On 3 months reassessment, documenting regression of the lung lesions.

Figure 2. Lung CT scan serial images revealing a diffuse ground glass pattern with peribronchovascular bilateral infiltrate on admission (A) and significant reversal of lung lesions on follow-up at 3 months (B).
