20 ans, mal au ventre, et si ce n'était PAS l'appendicite ?

A 20-year-old woman presents with severe abdominal pain, localized to her right iliac fossa. Blood tests reveal elevated inflammatory markers. The diagnosis seems obvious: classic appendicitis, right? And yet, this is where medical imaging reveals its true power! In this new clinical case, I'll show you how an abdominal CT scan helped avoid a diagnostic error and unnecessary surgery. On the agenda for this radiological investigation: 🔍 Detailed analysis of the CT scan: why the appendix is ​​not abnormal. 🦠 The discovery of the real culprit: striking images of diffuse colitis. ⚖️ The medical reasoning: how to differentiate infectious colitis from Inflammatory Bowel Disease (IBD). A crucial clinical case for understanding the pitfalls of abdominal emergencies, with a very favorable outcome for the patient thanks to a simple course of antibiotics! 👇 Have you ever had a false alarm with appendicitis? Tell me about it in the comments! ABOUT THIS VIDEO It was filmed and edited in Strasbourg in May 2026. The information I present is the most up-to-date based on my knowledge at the time. WHO AM I? Professor Mickaël Ohana, Professor of Radiology at the University Hospital of Strasbourg (France). I am a radiologist specializing in diagnostic cardiovascular and thoracic imaging. My specific area of ​​expertise is cardiac, thoracic, and vascular cross-sectional imaging (CT and MRI), for which I received training through two fellowships: 1/ one in Strasbourg, France (2011-2013) in thoracic imaging, 2/ and a second in Vancouver, Canada (2016-2017) in cardiac imaging. As a radiologist, I also provide on-call services and therefore perform emergency examinations for all patients. Having the privilege of working in a university hospital, we see exceptional and instructive cases every day, which I try to share with you. As an academic, I am also involved in research and teaching. Those interested can find the complete and up-to-date list of my scientific publications here: vu.fr/ohana WHY DO I MAKE VIDEOS? I'm passionate about radiology, and unfortunately, the central role of radiology and radiologists is still largely unknown, especially outside of hospitals. Similarly, our specialty is evolving at lightning speed, and new indications and possibilities are emerging very regularly. The goal is to share educational cases, articles, lectures, and thought-provoking material with you to highlight the radiologist's role and draw attention to new options in radiology. In short, to share knowledge with as many people as possible, from doctors to those simply curious: for a visual specialty like radiology, YouTube is the best platform!
