Unusual to see a presumed renal cell Ca this far off the reservation at presentation but it demonstrates a lot of the salient features of advanced disease.
Adrenal Regional Mets
Renal vein invasion
in this case into the normal variant retroaortic renal vein
Retroperitonal periaortic adenopathy
Lung Mets and Malignant Effusion
A very uncommon but also very important event. There is an association with popliteal artery injury, be it dissection or transection/laceration.
anterior and posterior dislocations most common
in my experience, posterior dislocations much more common, but sample bias is substantial because this is a rare event
structural disruption of the knee joint including cruciate ligaments and collateral ligaments, often with associated meniscal tears.
on MRI, the knee is usually “trashed”.
reports end up being lengthy because of the extent of injury.
associated popliteal artery injury estimated at 30%.
Rare, and rarely visible on studies because of the artifact, this little gem compliments the
Probably will be seeing more of these as acceptance appears to be on the rise. As a bone guy, it’ll be interesting to see if there are any long term complications associated with infection.
This is a fairly uncommon finding but the findings in this case are clearly posttraumatic. There is an impaction fracture the greater tuberosity and the labrum is essentially circumferentially torn even though the tear is not visible in the posterior labrum. Although not visible, it is still likely present. The glenoid avulsion of the glenohumeral ligament is clearly visible on the annotated images.
Animated Rocker Loops
And altered mental status to boot. I’d be more worried about a steady gait in a one year old.
