🔎 HRCT CHALLENGE: How many interstitial pneumonia patterns can you identify? 👩 Patient: 37-year-old woman Sometimes, one pattern is not enough to describe the complexity of an HRCT examination. 🎥 Watch the video carefully and assess the distribution of fibrosis, ground-glass opacities, consolidation and pleural abnormalities. 💬 How many patterns can you identify? Which features support your interpretation? I will discuss this case during Part 2 of my live lecture on the 2025 ERS/ATS Update on the Classification of Interstitial Pneumonias, using practical HRCT cases to explore combined patterns and their diagnostic implications. 📅 Friday, 30 October 2026 🕔 5:00 PM Cairo time 🎥 Missed Part 1? The recording is available, covering BIP, DAD, AMP and NSIP, with practical HRCT interpretation, diagnostic reasoning, and illustrated video cases. 📲 For registration and access details: WhatsApp +20 120 467 8455 #Radiology #HRCT #InterstitialLungDisease #ChestImaging #ERSATS #ThoracicRadiology

🔎 HRCT CHALLENGE: Can you identify the predominant interstitial pneumonia pattern? A 70-year-old woman presents with shortness of breath. She has a history of breast cancer treated with bilateral mastectomy and breast reconstruction. HRCT findings suggest an interstitial lung injury. The subsequent clinical course showed partial improvement after treatment, but the lung injury progressed to fibrosis. What is the predominant HRCT pattern? A️⃣ Bronchiolocentric interstitial pneumonia (BIP) B️⃣ Diffuse alveolar damage (DAD) C️⃣ Non-specific interstitial pneumonia (NSIP) D️⃣ Organising pneumonia (OP) 💬 What is your answer, and which HRCT features support it? I will discuss this case, the diagnostic reasoning and the relevant imaging clues during Part 2 of my live lecture on the 2025 ERS/ATS Update on the Classification of Interstitial Pneumonias. 📅 Friday, 30 October 2026 🕔 5:00 PM Cairo time The session will focus on practical HRCT interpretation, overlapping patterns and the distinction between morphological patterns and their underlying causes. 📲 For registration and access details, contact me on WhatsApp: +20 120 467 8455 #Radiology #HRCT #ChestImaging #InterstitialLungDisease #ERSATS

📢 2025 ERS/ATS Update on the Classification of Interstitial Pneumonias 🔬 Part 2 — Live Online Lecture | Friday, 30 October What has changed in the classification of interstitial pneumonias, and how can we translate these changes into better everyday HRCT interpretation? Following our first session, I invite you to join me next Friday, 30 October 2026, at 5:00 PM Cairo time, for Part 2 of this practical, case-based lecture. 🔎 Part 1: More than a classification update The Part 1 recording is available and includes: ▪️ Why was an update needed? ▪️ Four major advances and what has changed since 2013 ▪️ Why separate interstitial and alveolar filling disorders? ▪️ BIP: The most important new pattern — essentials, practical reporting and the distinction between BIP and ACIF ▪️ From AIP to DAD: understanding idiopathic and secondary forms ▪️ DIP becomes AMP: what the new terminology means ▪️ NSIP: essentials from the 2025 ERS/ATS statement ▪️ MinIP and mosaic attenuation: technical considerations for HRCT interpretation The session includes illustrated and video cases, practical radiological tips, pattern differentiation and diagnostic reasoning. 🎯 Part 2: What will we cover? ▪️ Organising pneumonia (OP) ▪️ Usual interstitial pneumonia (UIP) ▪️ Pleuroparenchymal fibroelastosis (PPFE) ▪️ Lymphoid interstitial pneumonia (LIP) ▪️ Respiratory bronchiolitis–interstitial lung disease (RB-ILD) ▪️ Combined interstitial pneumonia patterns 💡 What makes this approach different? This is not simply a review of disease definitions or a reproduction of classification tables. We focus on how to interpret HRCT findings, distinguish overlapping patterns and use imaging to guide diagnostic reasoning. Through practical examples, we explore questions such as: 🔹 When does a morphological pattern suggest a specific disease—and when does it not? 🔹 How can distribution and associated findings refine the differential diagnosis? 🔹 How should we approach BIP without automatically diagnosing HP? 🔹 How can we distinguish coexisting patterns and report them accurately? 🔹 How do we integrate HRCT, clinical history and histopathology? The goal is to make the 2025 ERS/ATS classification practical, understandable and applicable to daily radiological practice. 📅 Join Part 2 live Date: Friday, 30 October 2026 Time: 5:00 PM Cairo time Format: Live online lecture 🎥 Missed Part 1? The recording is available, so you can catch up before the next session. 📲 For registration and access details, contact me on WhatsApp: +20 120 467 8455 I look forward to welcoming colleagues interested in a more practical and structured approach to interstitial lung disease and HRCT interpretation. #Radiology #ChestImaging #HRCT #InterstitialLungDisease #ILD #ERSATS #ThoracicRadiology

📢 SPECIAL LIVE ONLINE LECTURE Updated Classification of Interstitial Pneumonias — ERS/ATS 2025 What has really changed, and how will it affect our daily practice? The 2025 ERS/ATS statement introduces important changes to the international classification of interstitial pneumonias. Understanding these changes is essential for accurate HRCT pattern recognition, diagnostic reasoning and multidisciplinary discussion. Join me for a 2-hour, clinically oriented session exploring the new classification through practical radiological examples. 🔎 What will we discuss? ▪️ From DIP to AMP: Why the terminology has changed. ▪️ From AIP to DAD: Understanding idiopathic and secondary forms. ▪️ Bronchiolocentric interstitial pneumonia (BIP): A new pattern, its HRCT features and its relationship to hypersensitivity pneumonitis and other causes. ▪️ NSIP and BIP: Distinguishing non-fibrotic from fibrotic patterns. ▪️ Combined patterns: Recognising overlapping patterns, including PPFE with UIP. ▪️ Practical HRCT cases: Applying the updated terminology to real-world imaging findings. ▪️ Diagnostic confidence: What should we report, and what still requires clinical and multidisciplinary integration? 🎯 Designed for: Radiologists, pulmonologists and physicians involved in the diagnosis and management of interstitial lung diseases. 📅 Friday, 23 October 2026 🕔 5:00–7:00 PM Cairo time 💻 Live online lecture 📩 To join or enquire about participation, contact me via WhatsApp: +20 120 678 4555 A focused opportunity to understand the new classification and translate its changes into everyday clinical and radiological practice.

A challenging chest CT—and a perfect example of why pulmonary nodule interpretation matters. A 65-year-old man with chest pain and a remote history of severe COVID-19 pneumonia requiring hospitalization 6 years ago. The CT shows two very different stories: 🔹 Chronic interstitial lung abnormalities • Upper-lobe predominant pleural/parenchymal fibroelastosis–like change (PPFE pattern) • Lower-lobe predominant residual organizing-pneumonia changes 🔹 Multiple pulmonary nodules along the adenocarcinoma spectrum • Dominant right upper lobe juxtapleural part-solid nodule, 23 mm, with a 21-mm solid component • Left upper lobe peripheral solid nodule, 5 mm • Left upper lobe para-aortic pure ground-glass nodule, 7 mm The challenge is not simply to see the nodules. It is to understand: Which findings are related to the previous lung injury—and which findings require a completely different approach? And, more importantly: How should we interpret and manage incidentally detected subsolid nodules? This is exactly the type of case discussed in my lecture: “Adenocarcinoma: How to Interpret Incidentally Suspected Adenocarcinoma Spectrum” We go through the Fleischner Society 2017 recommendations for incidentally detected pulmonary nodules, and also discuss how the approach changes when we are working within a lung cancer screening program using Lung-RADS v2022. The same nodule can require a different framework depending on the clinical context. 🎓 The full DLD Course is currently available for enrollment. The Adenocarcinoma lecture is also available for X subscribers. If you interpret chest CTs, this is one lecture worth having in your toolbox.

📚 DLD Course — Halfway Completed! We have now completed half of the DLD Course🎯 So far, we have covered: 🔹 Reticular pattern — 1 session 🔹 Nodular pattern — 3 sessions 🔹 Ground-glass pattern — 9 sessions Each session is approximately 2 hours, with a strong focus on practical HRCT interpretation and clinical decision-making. We have now completed the Ground-Glass Pattern, including the pulmonary adenocarcinoma spectrum. ⏸️ Planned 3-Week Break We will take a planned break for three Fridays and resume the course on: 📅 Friday, September 25 We will then continue with: 🔸 Consolidation pattern 🔸 Cystic pattern 🔸 Mosaic pattern New participants are welcome! The 3-week break is a great opportunity to join the course now and catch up through the recorded sessions before the live sessions resume. Half of the course completed — and we still have a lot more HRCT to explore!

GROUND-GLASS OPACITY PATTERN — PART 9 PULMONARY ADENOCARCINOMA From GGO to Practical Reporting What does the CT really tell you when you encounter a ground-glass or part-solid pulmonary nodule? In this session, we will explore the pulmonary adenocarcinoma spectrum from a radiologic perspective: 🔹 AIS • MIA • LPA • IMA 🔹 Pure ground-glass nodules 🔹 Part-solid nodules 🔹 Consolidative and multifocal/diffuse presentations 🔹 Cystic airspaces associated with adenocarcinoma 🔹 Radiologic–pathologic correlation 🔹 Real-world cases and diagnostic pitfalls But the most important part is the practical approach: What should the radiologist actually report? We will discuss reporting recommendations and how to approach these lesions in clinical practice, including: 🔸 When and how to apply the Fleischner guidelines 🔸 When Lung-RADS applies 🔸 How to describe pure GGO and part-solid nodules 🔸 How imaging features can suggest the underlying adenocarcinoma spectrum 🔸 What matters on follow-up and what should trigger further action Friday, August 21, 2026 | 5:00 PM Cairo Time 💻 Live Online Session Individual registration is available for those interested specifically in this topic 📲 Registration & course details: WhatsApp: +20 120 678 4555

I got the Trabzonspor cap here in Egypt 😎 Did anyone beat me to it, Mo? 😉

Next Session | Ground-Glass Opacity Pattern — Part 8 We have already discussed many of these diseases in previous pattern-based sessions—but this time, we will look at them from a completely different perspective. The question is not simply “What diseases cause ground-glass opacity?” It is: What diseases can present with a chronic ground-glass pattern, and how can we recognize them when they don't show their more familiar appearance? In this session, we will discuss: 🔹 Atypical sarcoidosis presenting with chronic GGO Moving beyond the typical sarcoidosis pattern of perilymphatic nodules that we discussed in the Nodular Pattern session, and exploring the different HRCT patterns of chronic GGO-predominant sarcoidosis. 🔹 Respiratory bronchiolitis and follicular bronchiolitis revisited Previously discussed as causes of centrilobular ground-glass nodules. This time, we will see cases presenting with patchy GGO rather than discrete centrilobular nodules, and explore their associations with smoking-related disease and connective tissue disease/LIP, respectively. 🔹 Pneumoconiosis presenting as chronic GGO Not every pneumoconiosis presents with the familiar nodular pattern. We will look at less typical GGO-predominant presentations and the clues that help us recognize them. 🔹 Pulmonary alveolar proteinosis (PAP) Beyond the classic crazy-paving appearance, with multiple real-world cases demonstrating the spectrum of HRCT appearances and potential diagnostic pitfalls. 🔹 Lipoid pneumonia How can we recognize lipoid pneumonia when obvious fat attenuation is absent? We will integrate the radiological clues with the clinical history and discuss how to distinguish lipoid pneumonia from mucus bronchogram and mucus impaction. This is the 8th session of our Ground-Glass Opacity Pattern series. After exploring both acute and chronic GGO presentations throughout the previous sessions, we are now continuing with the chronic GGO spectrum. And there is still one more session to complete the GGO pattern: Part 9 will move into adenocarcinoma and other lung cancers presenting with ground-glass opacity, completing the GGO pattern from inflammatory and interstitial diseases to neoplastic causes. Diseases do not always read the textbook. Their HRCT appearance can change, and recognizing the pattern in front of you is the first step toward the correct diagnosis.

Hemoptysis + diffuse ground-glass opacity = DAH? Not always. A 65-year-old man presented with cough, breathing difficulty and hemoptysis. His HRCT showed bilateral bat-wing ground-glass opacities, marked cardiomegaly and a dilated main pulmonary artery. At first glance, hemoptysis with diffuse GGO and consolidation may make us think of diffuse alveolar hemorrhage (DAH), particularly from systemic vasculitis. But there is an important diagnostic trap here: Pulmonary edema can also cause hemoptysis. So when you see diffuse GGO in a patient with hemoptysis, don't let the clinical symptom alone drive you toward DAH. Look at the distribution of the GGO and, importantly, the cardiovascular findings. In this case, the bat-wing distribution, marked cardiomegaly and dilated pulmonary artery provide important clues toward pulmonary edema related to cardiac disease and pulmonary hypertension. 👉 Hemoptysis does not necessarily mean DAH. Sometimes, the lung is telling you about the heart. This is also one of the important pitfalls I discussed in my recent acute GGO session of the Diffuse Lung Disease HRCT course.
