Radiology Rounds – 11/22/22

We are back with another #RadiologyRounds for you!

A middle-aged male presents with sub-acute fatigue, fevers and dyspnea on exertion. His admission labs are notable for severe neutropenia (ANC < 500)

This patient has evidence of a halo sign which represents local vessel invasion or hemorrhage

The patient undergoes evaluation. RVP, sputum culture and serum galactomannan and 1-3-B-d-glucan are negative. A BAL with transbronchial biopsies are obtained.

The patient was found to have pulmonary mucormycosis and was started on IV liposomal amphotericin-B.

Radiology Rounds – 11/8/22

This week’s #RadiologyRounds is brought to you by our newest contributor, Nick Ghionni! We’ll dive into a classic Radiology Sign and talk about what it represents, and how it helps inform your differential.

In this case, the patient underwent a biopsy that showed no malignancy but grew NTM! Given that NTM can be superimposed on malignancy, repeated biopsies were done that corroborated. She is being treated with close monitoring.

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.

For #RadiologyRounds this week we have a mystery case from the pulmonary clinic complete with imaging and exploration of PFTs. Follow along for some great clinical pearls and teaching points about lung function tests. Graphics made with the help of outstanding educator Kaitlin Seitz.

What imaging views would you get next?

A) Supine and prone

B) Inspiratory and expiratory

C) High resolution

D) With contrast

What test would you get next?

A) Bronchoscopy

B) ECHO

C) PFTs

D) Lung US

What do these PFTs show?

A) Restriction concerning for ILD

B) Restriction concerning for obesity

C) Restriction concerning for weakness

D) Mixed obstruction and restriction

The patient was referred to neurology and ultimately diagnosed with severe mixed sensory and motor chronic axonal polyneuropathy.

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.

Radiology Rounds – 8/16/22

It is Tuesday and we have another Radiology Rounds we can’t wait to share with you. Follow along and see if you select the right answer as we go through different presentations of sarcoidosis and pick your answer! What stage is it?!

A middle-aged man presents to you after he was found to have hilar adenopathy on a routine chest x-ray.

A middle-age man presents with dyspnea on exertion, night sweats and weight loss. You see evidence of bilateral apical disease, and fibrosis with evidence of honeycombing on chest CT.

A young woman presents with dyspnea on exertion and was found to have hilar adenopathy with parenchymal disease.

An elderly man presents with dyspnea on exertion and was found to have nodular parenchymal disease without extensive lymphadenopathy.

Radiology Rounds – 7/12/22

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.
