We have another great case in our Fellows’ Case Files coming today from UMass Chan. Listen in for a great discussion about a fascinating case with interesting physical exam and radiographic findings.

Case Presentation
A 75 y/o F presenting with acute on chronic SOB, cough, L sided chest pain and rash. She has had ~7 months of progressive dyspnea, now a/w 2 months of productive cough, and several weeks of L sided chest pain and rash. She has been seen multiple times in the past two months for these sxs. During that time she received multiple antibiotic courses (urgent care, outpatient providers), including augmentin, azithromycin and levaquin, and asthma directed therapy (no steroids). Imaging throughout that time (CXRs, CTPE) show progression from a LLL infiltrate to bibasilar infiltrates. Despite these interventions, sxs continue to worsen. One month prior she was admitted to an OSH w/ continued worsening, vitals stable, exam nonfocal, mild leukocytosis but infectious w/u bland. Received broad spectrum abx. Bronch w/ BAL offers negative cultures, cytology, cell count w/ 66% neutrophils, 14% eosinophils. Discharged w/ dx of PNA on a 10 day course of levaquin and new exertional oxygen requirement of 2L. She then presents to Umass ~1 month later w/ continued progression of sxs
Key Learning Points
1. Formulate a differential diagnosis for non-resolving pneumonia
2. Evaluate the utility of transbronchial biopsy in the workup of undifferentiated ILD
3. Describe the clinical manifestations of antisynthetase syndrome and identify the differences in presentation associated with PL-12 positivity
