Name all the signs you can see on these sagittal T2 images from each breast. Next, name all the signs you can think of that signify MRI evidence of intracapsular implant rupture. Then be sure to scroll below the images to check your findings against mine.
Right breast (left) is collapsed; loop or lariat sign (two arrows); fall away sign (four arrows) when implant falls away from biological fibrous shell.
Left breast (on right) is normal with physiologic radial folds (arrow).
Other signs include: Linguine sign (the classic intracapsular rupture sign), and the bubble-mixing sign, both not present in this case. All represent intracapsular implant rupture.
Sometimes the history can change everything when it comes to evaluating a case. I wanted to show you one such example. Before you look at my findings, be sure to come up with your own answer for what you think is this patient’s underlying disease.
- 74-year-old with swollen toe.
- What is the underlying disease?
- What is the underlying deformity?
- What finding on MRI decides if the patient has osteomyelitis?
- Underlying disease: Diabetes
- Deformity: Bunion
- “Erasure sign” or cortical loss on short axis T1 MRI (long arrow)
- Infected bursitis (4 arrows) contiguous with bunion erosions (2 arrows) in the first metatarsal on MRI fat- and water-weighted imaging (images 2, 3, 4).
- ProScan Pearl: It is common to see reactive marrow swelling on water-weighted MRI images but if the cortex is not lost on T1 MRI it is not osteomyelitis.
I’d love for you to check out more cases I’ve shared by taking a look at this complimentary course.
All the best,
Staging in prostate cases has never been more important as we work to design an individualized care plan for each patient. With that in mind, I wanted to share this case with you. Before you look at my findings, think about what T-stage you would give this case with the info provided. And what PiRad score would you assign it? The nodes and bones are normal.
Findings: T3z, or in other words probable capsular invasion on the right T2 axial and coronal MRI (short arrows). On viewer’s left (patient’s right), is diffusion restriction (high signal arrows) and low signal on ADC parametric map (arrows). Mass is over 1.5 cm in size so this is a PiRads 5.
I’d love for you to check out this instructional video I created that will help you improve you PiRad scoring, as part of a larger complimentary online prostate course. Thanks.
All the best,
Guess that sport – MRI Case Review with Dr. Pomeranz
At ProScan, we specialize in sports injuries. We regularly read for professional sports organizations in the NFL, NHL and more. We review LOTS of MRI sports injury cases.
If you read MRI, or want to read more of it, chances are you see a lot of sports injuries, too!
I’m going to share a case with you of another athlete we saw recently who had a finger injury. I’d like for you to pause and try to guess the sport before you look at my findings. It’s a 35-year-old male with middle finger pain.
What is the injury? Which subtype or location specifically? What is most common “one” to tear? What is the most likely sport to cause this?
did you think about it?
hint: it’s not a football, hockey player or skier
- Pulley tear, middle finger (arrows) and tendon sags towards palm or volarly.
- A2 pulley at proximal third of proximal phalanx is injury.
- A2 is most common to tear.
The most likely sport? Rock climbing!
Hope you enjoyed the case review. If you need to brush up on your hand injuries, check out our Medical Imaging Quick Hits, where we go through several hand cases in detail. For a more thorough hand review, complete with several cases and 2 CME, I’d recommend our MRI Case Review Series.
More to come!
