This week’s #RadiologyRounds is coming from the pulmonary clinic. Follow us on Twitter to see the case and answer our polls live!
Given the patient’s weight loss and persistent symptoms despite trying some empiric therapies, a chest CT was obtained. PFTs were also ordered 🙂
The patient’s CT had tree-in-bud opacities, nodular consolidations, scattered micronodular opacities, and airway thickening.
The pt had an induced sputum but could not produce a sample. She underwent bronchoscopy + lavage and her AFB smear was positive with negative TB NAAT. The culture ended up growing M. chimaera! Does that explain her symptoms? Here are the diagnostic criteria for pulmonary NTM:
All other testing was negative and the patient was diagnosed with pulmonary NTM. After a long discussion about treatment (an interesting topic for another day!!) she was started on triple antibiotic therapy and after 9 months her cough had resolved and she was gaining weight.
Welcome to another episode in our Pulm PEEPs Fellows’ Case Files series! The purpose of this series is to highlight and amplify the incredible clinical work that is done by pulmonary and critical care fellows, share fascinating cases, and assemble a diverse network of pulmonary and critical care educators. Today we’re headed to Baylor College of Medicine to hear about a fascinating case. Tune in, let us know what you think on Twitter, and let us know if you have a great case to share!

A 60s-year-old man with seropositive RA on Rituximab presents with dyspnea and cough, and overall “not feeling well.” For the past week, he has had malaise, body aches, and subjective fever. For the past 3 days, he has had acutely worsening dyspnea that is worse with exertion, but present at rest and a cough with scant sputum production. He had been on Methotrexate previously but within the last year developed pancytopenia and MTX was stopped and he was switched to adalimumab/Humira. His pancytopenias did not resolve, and he was ultimately diagnosed with Felty syndrome (a triad of RA, neutropenia, and splenomegaly) and switched to rituximab every 6 months with his last dose being 4 months ago. During the last week, he tried taking prednisone 10 mg a day but his symptoms did not improve.

This week, we have another great case episode on Pulm PEEPs! We are joined by Emily Fridenmaker who helps us think through a fascinating case presenation.
Meet Our Guests
Emily Fridenmaker is a Pulmonary, Critical Care, and Sleep Medicine fellow at the University of Kentucky College of Medicine. She went to medical school at West Virginia school of medicine and did her internal medicine residency at Charleston Area Medical Center
A middle-aged woman presents with 2-3 weeks of mild but progressive shortness of breath with exertion associated with low-grade fevers, worsening night sweats, and fatigue. Further history reveals a progressive non-productive cough and weight loss. She has a past medical history of neurologic dysfunction over two years and a working diagnosis of chronic inflammatory demyelinating polyneuropathy and is pursuing treatment in Mexico due to cost limitations. She has been receiving prednisone 10 mg daily and azathioprine. Aside from travel history to Mexico, her social history is notable for prior employment in a candle factory, and for hiking with some cave exploration. She is a former 20 pack-year smoker and has rare alcohol use.
This week we’re sharing a distinct radiology pattern on chest X-ray and CT scans that should raise its own differential. Make sure to listen to our case episode next week to hear more about this patient and the diagnostic workup.
The Pulm PEEPs are excited to bring our first mystery case! Kristina Montemayor and Dave Furfaro hear a fascinating case presentation from Pulm PEEPs senior editor Ansa Razzaq. Join us as we work through this case together to come to a diagnosis, and share our thought process along the way. Come back to these show notes afterward, or once you’ve solved the case yourself, for some key teaching pearls and representative images.
A 66-year-old woman with no smoking history and past medical history of previously well-controlled asthma is referred to pulmonary clinic after multiple recent episodes of dyspnea, wheezing, and coughing. The episodes have features consistent with asthma exacerbations; however, they are also associated with migratory infiltrates. She has been treated with multiple courses of antibiotics and steroids, and despite escalating therapy, the episodes are occurring more frequently and she was worsening overall exercise tolerance. Listen in to hear more and try to solve the case!
