Figure 5. Clinical course following treatment of lung injury. This figure presents serial CT scans alongside the clinical course of the patient. Day 1 corresponds to the initial patient visit. Day 46 presents data from a drug-free follow-up, providing insights into the patient’s condition without therapeutic intervention. Day 66 reflects data collected after the first course of steroid pulse therapy, highlighting the immediate therapeutic impact. Day 194 shows the patient’s status post-completion of prednisone therapy, offering a longer-term perspective on treatment efficacy. The CT scans were performed with an axial slice thickness of 0.5 mm. CT, computed tomography.
