Radiology Rounds – 9/5/23

Tuesday is time for another #RadiologyRounds! Time for some CXR reading and a differential diagnosis mnemonic Two women presented to the hospital with similar presentations. They are both in their 80s with multiple weeks of cough, fever, and fatigue. Here are the CXRs

The CXRs both showed cavities. They are thick-walled (>4mm) and gas-filled. Cavitary lung lesions are seen within infiltrates, nodules, or masses. There can be an air-fluid level within the cavity. Cysts have thinner walls. The findings were confirmed on CT scan

Cavitary lung lesions can have a broad differential so it is helpful to have a systematic approach. To make it easy, when you see this just remember: CAVITY

Bonus points to anyone who can fill in the Y

Both patients were ultimately diagnosed with pulmonary abscesses which improved with prolonged courses of antibiotics with anaerobic and gram-negative coverage.

We are back with our first #RadiologyRounds of 2023!

While chronic lung infections and infertility are overlapping symptoms for CF and Primary Ciliary Dyskinesia, the history of neonatal respiratory syndrome, ear infections and lower lobe bronchiectasis are most consistent with PCD

In up to 50% of people with PCD, you can get complete reversal of thoracic and abdominal organs. In this film you can see the heart in the right hemithorax, the gastric bubble on the right with the liver on the left resulting in elevation of the left hemidiaphragm

In patients with clinical symptoms and two decreased levels of nasal nitric oxide these findings suggest a PCD diagnosis but evaluation of the cilia structure and function as well as genetic testing are other diagnostic evaluations to confirm a diagnosis of PCD

Primary ciliary dyskinesia is a autosomal recessive disorder that results in motile ciliary dysfunction and clinical manifestations can vary depending on which organs are involved

Time for another #RadiologyRounds! This case is authored by PulmPEEPs associate editor @TessLitchman. Great teaching ahead!

Trick question (sorry)! All of these features are present.

A bronchoscopy was performed and the patient was diagnosed with PCP. Additional testing confirmed a new diagnosis of HIV.

This patient was treated with high-dose Bactrim and IV steroids, in addition to being started on ART.

Time for another #RadiologyRounds!! This week we’re looking at the coronal CT scan views, which can be extremely helpful and are often under-utilized. Follow us on Twitter to work through Radiology Rounds cases as they come out.

Our patient had an elevated VEGF-D level, a renal angiomyolipoma identified on CT abdomen, and imaging with diffuse cystic lung disease confirming her diagnosis of LAM. Make sure to check out the ICUOnePager made by Dr. Nick Mark.
