Thank you to everyone who participated in the poll! The majority chose hypersensitivity pneumonitis, which is indeed a common diagnosis. However, it’s important to remember that sarcoidosis, often considered a “joker” in HRCT, can mimic hypersensitivity pneumonitis due to its

An intriguing HRCT scan of a 44-year-old female patient. 🔍 What anomalies or abnormalities do you see? Drop your observations in the comments below. #MedicalCaseStudy #HRCT #Radiology #MedicalCommunity #CaseDiscussion #XChallenge

In the comments, one of the findings observed is scimitar syndrome. Other findings include horseshoe lung and right lung hypoplasia, resulting in a mediastinal shift to the right. There is no dextrocardia, as the left ventricular apex is in its normal left-sided position

A 37-year-old male with persistent shortness of breath, unresponsive to antibiotic treatment, underwent a CT chest scan with IV contrast. What could be the underlying issue? Please share your thoughts and analyses in the comments below! #MedicalCase #Radiology #CTScan

This is the correct answer considering the findings and distribution. Perilymphatic nodules are indeed a key feature for recognizing alveolar sarcoidosis. Review the HRCT again to observe the nodules along the fissures. Additionally, could you identify the galaxy sign?

A known case of a 41-year-old male with hypersensitivity pneumonitis (HP). How would you categorize the pattern according to the available HP features? Is it typical or compatible with HP? When interpreting HP, don’t forget to specify whether it is fibrotic or nonfibrotic, as

We have two intriguing cases to discuss: a 79-year-old female and a 51-year-old male, both exhibiting a typical UIP pattern. One case involves idiopathic pulmonary fibrosis, while the other is secondary to rheumatoid arthritis. The anterior upper lobe sign is highly specific for

The propeller blade distribution (PBD) describes a UIP-IPF distribution variant characterized by a continuous gradient of peripheral fibrosis (honeycombing and/or reticulation) on axial images, twisting from posterior to anterior as the images progress from the lung bases toward

This case demonstrates profuse (extensive) ground-glass centrilobular nodules, characteristic of the typical subtype of hypersensitivity pneumonitis (HP). The absence of fibrotic changes supports a diagnosis of non-fibrotic typical HP. Additionally, linear and radial-like

A challenging case of a 28-year-old female with overlap syndrome (SLE + Polymyositis) and Raynaud’s disease. What do you observe in her HRCT? Share your thoughts and discuss your approach in the comments! #MedicalCaseStudy #Radiology #HRCT #Rheumatology #MedTwitter

I agree with most of the responses regarding the presence of specific signs of UIP related to CTD. The anterior upper lobe sign, four corners sign, and straight edge sign are all evident. However, I don’t agree that this should be classified as typical UIP. The absence of

Here’s an HRCT scan of a 15-year-old male showing multi-cystic lung disease. How would you approach the interpretation and diagnosis in this case? Share your insights and experiences with this challenging condition! #Radiology #PediatricPulmonology #MedTwitter
