A woman in her 30s with no past medical history presents with acute dyspnea, fever and a non-productive cough.
She has no sick contacts or recent travel. She is not on home medications and smokes cigarettes and occasionally vapes.
What is the predominant imaging abnormality?
She is found to have diffuse bilateral patchy ground-glass opacities with some interlobular septal thickening.
She has escalating oxygen requirements and was initially started on broad-spectrum empiric antimicrobial therapies
Her initial serum infectious work-up and RVP are negative. She denies any new occupational or home exposures. She does not appear to respond to antibiotics after 72 hours.
What is your leading differential at this time?
You proceed with a bronchoscopy with BAL to obtain a cell count and diff and culture data.
Which cell type would confirm your leading diagnosis?
You start empiric steroids (prednisone 60 mg daily) given concern for acute eosinophilic pneumonia. Within 48 hours she is weaned off HFNC and was discharged home on D7 on room air with close pulmonary follow-up.
She was amenable to tobacco cessation therapies and was followed closely outpatient with tapering of her steroids over 4 weeks.

As we approach the end of the year, we know that the hospital and clinic keep on rolling, so here is a CXR and pulmonary differential based #RadiologyRounds if you're on for the holiday blocks
A woman in her 50s has hypoxemia after being admitted with a femur fracture
What do you see on the CXR to help explain the patient's hypoxemia?
The CXR shows signs of a left upper lobe collapse. The upper lungs should be the most lucent, with increased opacity as you go down. LUL collapse can be subtle, but you can see increased haziness at the lung apex. There is also rib crowding and left hemidiaphragm elevation
We are back with our first #RadiologyRounds of the new academic year🫁
We have a young, immunocompetent man presenting with fever, weight loss and abdominal pain.
What abnormalities are seen on chest imaging?
He was found to have bilateral apical cavitary disease, centrilobular nodules and tree-in-bud opacities. He developed a productive cough with blood-tinged sputum as well as diarrhea.
Nothing like #RadiologyRounds to kick off a work week after a long weekend!
A middle aged man with metastatic esophageal cancer presents with 2 weeks of low grade fevers and more recently progressive dyspnea . Exam notable for late inspiratory crackles throughout the right lung
A CT scan was obtained and here are the images:
How would you describe these findings??
What is your lead differential when you see predominantly unilateral GGOs and consolidations?
For "#RadiologyRounds" today, we won't be looking at any imaging, but we'll be looking at some vent wave forms and examining dysynchrony! This is a re-booted @david_furfaro Tweetorial.
I hope you enjoy and this is an open invitation for all dysynchrony waveforms!🫁🚨
A 40s M is intubated for ARDS. In order to maintain lung protective ventilation, he was on high does of propofol, fentanyl and midazolam. His sedation is being weaned slightly now, and the RN calls for vent dysynchrony. His ventilator looks like this
Before delving into the type of dysynynchrony and management, based on these waveforms what is actually happening? Note: when we say “exhales” or “inhales” I am referring to the mechanical, vent-driven breaths
Wow great thoughts by everyone on this case! For a reminder, a man in his 40s has progressive dyspnea and fatigue after a mild COVID infection and this CT scan:
Many of you rightly pointed out
🔹Septal thickening
🔹Reticular infiltrates
🔹Pleural involvement and effusions
🔹GGOs
All of these features are present. What is strikingly prominent is the reticulation and septal thickening. With this we always want to think about the lung lobule and its features:
Prominent reticulation can be septal thickening from fibrotic processes causing honeycombing (UIP pattern as in IPF) or with fibrotic NSIP / OP .
This can also be due to diseases that impact the lymphatic system. These generally cause less distortion of the lobule structures
