Dr. Imran Lasker's Monthly Case Webinar #12: From Shoulder Dislocations to Variceal Bleeds

The Monthly Case Webinar #12 hosted by Dr. Imran Lasker on the Collective Minds Radiology platform offers a valuable opportunity for healthcare professionals to explore complex cases and enhance their diagnostic skills. We had the pleasure of hosting Dr. Lasker at the Collective Minds Stockholm office for this session, adding an extra layer of excitement to the webinar.

In this article, we'll delve into some of the key insights from the April 2023 webinar, focusing on the clinical and diagnostic aspects of the cases presented. Dr. Lasker's presence at our headquarters allowed for an even more engaging and interactive session, bringing the global radiology community closer together.

Anterior Shoulder Dislocation: Beyond the Obvious

The webinar kicked off with a case of anterior shoulder dislocation, demonstrating the importance of a systematic approach to image interpretation. Dr. Lasker emphasized the need to look beyond the obvious dislocation and search for associated injuries.

"When you get anterior dislocation that humeral head is going to go forward and actually a lot of the time at the initial point of injury it goes quite a lot further forward than you will see on the X-ray," Dr. Lasker explained.

He highlighted the importance of checking for Hill-Sachs lesions and Bankart lesions, which are common associated injuries in shoulder dislocations. These findings can significantly impact patient management and long-term outcomes.

The Sail Sign: A Key Indicator of Lung Collapse

Another intriguing case presented during the webinar was that of a patient with a sail sign on chest X-ray. This radiographic finding is indicative of left lower lobe collapse, with the upper lobe expanding to fill the space.

Dr. Lasker stressed the importance of considering patient positioning and image quality when interpreting these findings:

"You've got to try and explain away why those things are not there. So there may be there but we also have to try and look at the quality of the film."

This case underscores the need for radiologists to consider technical factors and potential pitfalls in image interpretation, especially when dealing with subtle signs of pathology.

Fecalization Sign: A Valuable Tool in Bowel Obstruction

One of the most practical insights shared during the webinar was the use of the fecalization sign in diagnosing small bowel obstruction. Dr. Lasker explained that the presence of feces-like material in the small bowel is a strong indicator of obstruction.

"You should really only have fluid so you only have like feces within a small bowel if there's obstruction there's lack of flow of fecal material through it gets sitting in that small bowel and the small bowel that's meant to do take fluid take fluid away from it and eventually becomes like feces within the bowel."

This sign can be particularly helpful in cases where the point of obstruction is not immediately apparent on imaging.

Variceal Bleeding: The Power of Contrast-Enhanced CT

The webinar also covered a case of variceal bleeding, demonstrating the value of contrast-enhanced CT in diagnosing and localizing the source of gastrointestinal hemorrhage. Dr. Lasker walked through the process of comparing non-contrast and contrast-enhanced images to identify active bleeding sites.

"When you look at this image and go from the similar area you can start to see that actually there is this hyper density there and compare the two."

This case highlights the importance of appropriate imaging protocols and the need for radiologists to be familiar with the appearance of active bleeding on CT.

Conclusion: The Value of Collaborative Learning

The Monthly Case Webinar series, hosted on the Collective Minds Radiology platform, provides an invaluable opportunity for radiologists and other healthcare professionals to learn from complex cases and share insights. As Saidul Islam, Application Specialist at Collective Minds and host of the webinar introduction, noted, these sessions foster a collaborative environment that enhances diagnostic skills and ultimately improves patient care.

By exploring a diverse range of cases, from common conditions like shoulder dislocations to more complex scenarios like variceal bleeding, participants gain practical knowledge that can be applied in their daily practice. The webinar series also emphasizes the importance of a systematic approach to image interpretation and the need to consider clinical context when making diagnoses.

As radiology continues to evolve, platforms like Collective Minds Radiology play a crucial role in facilitating knowledge sharing and professional development. By bringing together experts like Dr. Imran Lasker and providing a space for interactive learning, these initiatives contribute to the advancement of radiology practice worldwide.
