Biopsy of the lymph node reveals Hodgkins lymphoma. The patient agrees to start the standard chemotherapy regimen. A few months later, after the completion of 3 successful courses, the patient presents with a dry cough and progressively worsening shortness of breath. Her temperature is 37C 98.6F, the blood pressure is 11070 mm Hg, the pulse is 72min, and the respirations are 16min. Pulse oximetry shows an O2 saturation of 94 on room air. On spirometry, the patients FEV1FVC ratio is normal. Chest CT reveals bilateral diffuse cystic airspaces in middle and lower lung fields. Which of the following is the most likely cause of this patients current symptoms?? A: Drug-induced interstitial lung disease, B: Metastatic spread to the lungs, C: Development of chronic obstructive pulmonary disease, D: Transfusion-related acute lung injury, E: Development of bacterial pneumonia due to immunocompromised state,  <response>: This is a clinical vignette describing a 45-year-old woman with Hodgkins lymphoma who developed a cough and shortness of breath after receiving chemotherapy. The key findings are unintentional weight loss, cervical lymphadenopathy, biopsy confirming Hodgkins lymphoma, treatment with chemotherapy, development of cough and shortness of breath after chemotherapy, normal vital signs, oxygen saturation of 94 on room air, normal FEV1FVC ratio, and bilateral cystic changes on chest CT. The differential diagnosis includes:- Drug-induced interstitial lung disease: This is the most likely given the temporal relationship with chemotherapy and bilateral cystic changes on CT. Chemotherapy drugs can cause pulmonary toxicity.- Metastatic spread to the lungs: Less likely as cystic changes are not typical of metastases. Metastases also wouldnt explain the normal FEV1FVC ratio.- COPD: Unlikely given normal FEV1FVC ratio. No prior history of COPD. - TRALI: Unlikely as no mention of recent transfusion. - Bacterial pneumonia: Unlikely with normal vital signs and no fever. The cystic changes on CT are also not typical for bacterial pneumonia.A: Drug-induced interstitial lung disease
