🌍 Thank you to Dr. Tina Young Poussaint and Dr. Brigitte Bison for sharing their expertise and invaluable teaching pearls during today's IPNTN webinar. A heartfelt thank you as well to everyone who joined us from around the world for IPNTN Season VII: Take Five! Chapter III🧠 Your engagement, questions, and commitment to learning continue to make this global educational community so special. See you at the next session June 27, 2026 (June 28 for certain time zones) Stroke & Stroke Mimics #pedineurorad #IPNTN #PedRad #ASPNR @TYPoussaintMD @MirskyDavid @RLClarkeMD @laura1127md @drmankad @ArzuOztrkMD @alexandra_foust @HarumyYoshikawa @JamieClarkeRad

🎯 Final pearl from Dr. Brigitte Bison: When reviewing follow-up neuro-oncology imaging, don't focus solely on recurrence or secondary malignancies. ⚠️ Consider therapy-induced changes as part of the differential diagnosis. 📌 The best diagnoses come from combining careful observation, pattern recognition, and clinical context. #pedineurorad #IPNTN #PedRad #ASPNR @MirskyDavid @RLClarkeMD @laura1127md @drmankad @ArzuOztrkMD @alexandra_foust @HarumyYoshikawa @JamieClarkeRad

Dr. Brigitte Bison continues reviewing educational cases with an important reminder: A systematic and comprehensive image analysis remains one of the most powerful tools in neuroradiology. 🚨 When evaluating medulloblastoma: 🧠 Think about dissemination first. 🔍 If it looks unusual, reconsider the differential. 📈 Recurrences usually resemble the original tumor. ⚡ DWI is your friend—high cellularity and most MB metastases show restricted diffusion. Small clues. Big impact. #pedineurorad #IPNTN #PedRad #ASPNR @MirskyDavid @RLClarkeMD @laura1127md @drmankad @ArzuOztrkMD @alexandra_foust @HarumyYoshikawa @JamieClarkeRad

Stay tuned! Continuing IPNTN Season VII: Take Five! Chapter III with Dr. Brigitte Bison of University Hospital Augsburg Germany! 🧠 Key pearls when reviewing the pituitary region: ✅ First, ask: What is normal? • Be aware of physiological age-related changes • Recognize reactive changes that may mimic pathology 🔍 For the differential diagnosis: • Is the posterior pituitary bright spot present? (suggesting an intact hypothalamo-pituitary axis) • Carefully assess the anatomy (stalk, pituitary gland, optic chiasm, anterior recess of the third vent for mets) 📋 Context matters: Age, sex, and clinical circumstances are often essential to reaching the correct diagnosis. ✨ Small details can make a big difference in the pituitary-hypothalamic region. #pedineurorad #IPNTN #PedRad #ASPNR @MirskyDavid @RLClarkeMD @laura1127md @drmankad @ArzuOztrkMD @alexandra_foust @HarumyYoshikawa @JamieClarkeRad

⚠️ Not everything that looks like a tumor is a tumor. 🧠 Cases like these remind us that the most important diagnosis may be the one not initially considered. #pedineurorad #IPNTN #PedRad #ASPNR @TYPoussaintMD @MirskyDavid @RLClarkeMD @laura1127md @drmankad @ArzuOztrkMD @alexandra_foust @HarumyYoshikawa @JamieClarkeRad

🧠 A fascinating case by Dr. Tina Young Poussaint. What imaging clues can help distinguish infection such as tuberculosis in this case from neoplasm when the appearances are strikingly similar? A great example of why clinic radiologic correlation remains essential. 🔍 Key takeaway: Keep a broad differential diagnosis when evaluating leptomeningeal disease, and always correlate imaging, clinical findings, and pathology. #pedineurorad #IPNTN #PedRad #ASPNR @TYPoussaintMD @MirskyDavid @RLClarkeMD @laura1127md @drmankad @ArzuOztrkMD @alexandra_foust @HarumyYoshikawa @JamieClarkeRad

Attending IPNTN for the 7th consecutive year, continues to inspire me with a wealth of knowledge and renewed passion It has significantly boosted my confidence in reporting ped neurorad cases. @drmankad @amyfjuliano @irhkch @laura1127md

😎And that's a wrap on the first session of Season VII of IPNTN! Amazing session on Head and Neck Imaging! Thank you to our presenters, Dr. Amy Juliano @amyfjuliano and Dr. Kevin Fung @irhkch for sharing your knowledge and expertise with us! ⏰Join us next time! Session 2, Neurometabolic Disorders, on April 25, 2026 🔗Register here: aspnr.org/learning/internati…

🌍Live at IPNTN Season VII, Session 1🌍Head and Neck Pathologies, Take 5! with @amyfjuliano 💡Great take home messages from this rich educational presentation on some important topics in head and neck imaging!

🌍Live at IPNTN Season VII, Session 1🌍 Head and Neck Pathologies with @amyfjuliano 💡 Cholesteatoma can erode and create appearance of surgical change in the middle ear, but lining of cholesteatoma remains, and can lead to further destruction over time. 🌟Know about the sheet-like cholesteatoma!🌟

🌍Live at IPNTN Season VII, Session 1🌍 Head and Neck Pathologies, Take 5! with @amyfjuliano 💡Type II tympanoplasty involves reshaping the native incus and replacing it, interposed between the malleus and stapes, creating an "autologous columella". This tympanoplasty technique is almost exclusively performed in kids! 🌟If the incus looks funny, consider whether it could be this type of incus interposition.🌟

🌍Live from IPNTN Season VII, Session 1🌍 Head and Neck Pathologies, Take 5! with @amyfjuliano 💡Think carefully about the wording of reports! Mastoiditis is a clinical diagnosis, coalescent mastoiditis and other complications of mastoiditis should be assessed by imaging. And remember, not all mastoid opacification is infectious.

🎉We are still live, at IPNTN Season VII and going strong!! Join us 🌟NOW🌟, Take 5! Head and Neck Pathologies, brought to us by Amy Juliano, MD. @amyfjuliano 🔗Register here: aspnr.org/learning/internati…

🌍Live at IPNTN Season VII🌍 With @irhkch 💡CM-AVM syndrome due to pathogenic RASA-1 mutation. Biopsy is important to establish genetic diagnosis, not only for genetic counseling but also to allow for targeted therapy.

🌍Live at IPNTN with @irhkch 🌍 💡We must think carefully if biopsy is appropriate, especially if a vascular lesion is possible. And remember, 🌟not all that has high T2WI signal is a vascular lesion!🌟 MR can be misleading, we must take into account the history and clinical presentation as well. @irhkch

🎉We are live, let's get this party started!! Join us 🌟NOW🌟, as we kick off IPNTN Season VII, Session 1, with Take 5! Vascular anomalies in the head and neck region, brought to us by Dr. Kevin Fung @irhkch 🔗Register: aspnr.org/learning/internati…

⏰1 hour to go, let the countdown begin! We are about to kick off Season VII of IPNTN, and it is going to be a good one! It's not too late to register!
