case_images: Computed tomography (CT) on admission showing chronic bronchitis with bilateral lung infection (A); CT presentation on day 14 of hospitalization (day 3 of meropenem administration): No obvious lesions in both lungs. However, multiple enlarged lymph nodes are seen in the mediastinum and bilateral axillae (B).

case_images: Computed tomography (CT) of the chest revealed chronic bronchitis with bilateral lung infections (Figure 1). Although a chest CT scan showed no obvious lung lesions (Figure 1), it revealed multiple enlarged lymph nodes in the mediastinum and bilateral axillae.
case_images: On days 10-12 of Pip/taz, the patient develops hyperthermia with persistently elevated PCT but normal eosinophils. After discontinuing Pip/taz and administering meropenem for 72 h (Day 15), the patient develops the characteristics of DRESS reaction (generalized rash, elevated eosinophils, hematologic abnormalities, and organ involvement), along with a markedly elevated PCT. After stopping the sensitizing drug and giving corticosteroids and anti-allergic drugs for about 1 week, the DRESS reaction subsides, and PCT decreases.
