Dr. Imran Lasker's Monthly Case Webinar #19: From Pancreatitis to Gouty Tophus
The Monthly Case Webinar #19, hosted by Collective Minds Radiology in November 2023, provided a wealth of knowledge for radiologists and medical professionals alike. Led by the esteemed Dr. Imran Lasker, this webinar covered a diverse range of cases, from chest x-rays to complex MRI scans. Let's dive into the key insights and learning points from this enlightening session.
Introduction and Overview
The webinar kicked off with Dhaanish Parvez, a Product Specialist at Collective Minds, introducing the session and highlighting the importance of collaborative learning in radiology. The webinar featured cases donated by Dr. Johan Diam, a consultant radiologist from Belgium, showcasing the global nature of this educational initiative.
Case 1: The Subtle Signs of Pneumothorax
The first case presented a chest x-ray that initially appeared unremarkable. However, Dr. Lasker demonstrated the importance of a systematic approach in identifying subtle abnormalities.
Key points:
- Importance of assessing patient rotation in chest x-rays
- Identification of a right-sided pneumothorax
- Recognition of a small pleural effusion (potential hemothorax)
Dr. Lasker emphasized the need to consider clinical context, stating, "In the context of trauma, this could be hemothorax." This case highlighted the importance of thorough examination and consideration of patient history in radiological interpretation.
You can view the full discussion of this case at 2:31 in the webinar video.
Case 2: Unraveling the Complexities of Head CT
The second case focused on a CT scan of the head, demonstrating the importance of understanding normal anatomical variations and recognizing subtle pathological changes.
Key insights:
- Identification of small vessel disease
- Recognition of subdural hematoma along the falx cerebri and tentorium
- Assessment of mass effect and midline shift
Dr. Lasker provided a valuable tip for distinguishing between subdural and extradural hematomas: "If you've got like a pair of glasses... extra pair of lenses for extra eyes and therefore this would be... extra eyes is an EXT is a lens form which would be an extradural."

Case 3: Pancreatitis - Beyond the Obvious
A CT scan of the abdomen and pelvis revealed a case of pancreatitis, but Dr. Lasker used this opportunity to discuss broader considerations in abdominal imaging.
Important takeaways:
- Recognition of pancreatic inflammation and surrounding fat stranding
- Consideration of potential complications such as splenic vein thrombosis
- Importance of assessing for calcifications in mesenteric vessels
"Complications of pancreatitis can be... you got your splenic vein which is sitting right next to pancreas. You just got to look is there... does that look like it's blocked off because that could be a problem," Dr. Lasker explained, emphasizing the need to look beyond the primary pathology.
This case discussion begins at 32:32 in the video.
Case 4: The Intriguing Intraosseous Lipoma
A pelvic x-ray case donated by Dr. Johan Diam presented an opportunity to discuss the approach to bone lesions.
Key learning points:
- Systematic approach to assessing bone lesions (aggressive vs. non-aggressive)
- Characteristics of intraosseous lipoma
- Importance of considering lesion location and potential impact on bone strength
Dr. Lasker provided a valuable framework for assessing bone lesions: "If all you do when you see these kind of x-rays is make a decision is this aggressive versus non-aggressive... that's the big thing."
For the full discussion on this interesting case, refer to 36:38 in the webinar.
Case 5: Unmasking Gout in Knee MRI
The final case presented a challenging knee MRI, ultimately revealing an unexpected diagnosis of gout.
Critical insights:
- Systematic approach to knee MRI interpretation
- Recognition of chondral surface loss and bone marrow edema
- Identification of extra-articular soft tissue lesion (gouty tophus)
Dr. Lasker's explanation of the findings was particularly illuminating: "Whatever this material is is not within the actual joint so it's actually extra-articular isn't it? It's outside the joint... extra-articular periarticular... This is gout."
To see the full analysis of this complex case, watch from 41:38 in the video.
Conclusion
The Monthly Case Webinar #19 by Collective Minds Radiology provided an invaluable learning experience for radiologists at all levels. From subtle chest x-ray findings to complex MRI interpretations, the cases presented emphasized the importance of a systematic approach, consideration of clinical context, and thinking beyond the obvious in radiological diagnosis.
As Dr. Lasker concluded, "The whole point is if you're interested in Radiology hopefully you enjoy it. It's a bit of entertainment, a bit of enjoyment, and a bit of getting to know each other."
For those looking to further their radiological knowledge and skills, the full collection of cases from this webinar is available on Collective Minds. Additionally, you can learn more about Dr. Imran Lasker and his contributions to radiology education.
