5 year old who fell off a slide with an unexpected finding. [Musculoskeletal] [XR]
5 year old who fell off a slide.
Initial imaging shows a comminuted fracture through the distal humerus, compatible with a supracondylar fracture. Nothing else appreciable here, except maybe in retrospect some lucency of the distal humerus where the fracture is.
4- and 7-month follow-up radiographs shows a growing lucent lesion of the distal humerus, expanding the bone there. It has a multicystic appearance. A diagnosis of large simple bone cyst versus aneurysmal bone cyst was proposed.
12 month follow-up was done after the cyst was opened surgically, its contents scraped off, and the resulting cavity was packed with allograft bone chips. At surgery, this turned out to be an aneurysmal bone cyst.
5 year follow-up shows involution of the cyst cavity with some residual heterogeneity and a bone spur at the anterior aspect of the distal humerus.
I know some of those words!
Bone break! Why so weak? -> Oh, tumor surprise! -> Tumor growing, bad! Make bone weak(er)! -> Fix fix fix. Luckily not a cancer. -> Good.
The explanation went beyond ELI5 and straight to Tarzan Speak.
Me not lie. Me like small words from smart man.
Why say many word when few word do trick?
ELITarzan should be a thing.
Me like he go full Kevin!
Have you seen how some 5 y.o. speaks?
Best tl;dr I've seen :)
You are a wonderful human being. I really appreciate you.
Me too, words like „a“, „month“, „shows“.
Please keep doing this. Tremendously interesting. One of two favorited communities (er, instances?) of mine.
Thank you kind person.
Thank you! Much appreciated.
what's the second one?
wait
cysts can grow inside of bone?
Yes, cysts can form in bone.
However, this particular entity, aneurysmal bone cyst, is the name of an actual tumor that happens to produce a lot of cysts.
You can see the other case I posted today for what an ABC looks like on MRI - I think you see why it's called an aneurysmal bone cyst. Unfortunately, that appearance is not specific for ABC. That other case did turn out to be cancer.
I pity those who have broken a bone
/c/neverbrokeabone?
I broke my pinky toe by running full speed, shoeless into a door frame. That was 10 years ago and that shit still nags me on cold/damp days or when I lean on it for too long.
Did the same swinging my leg over a baby gate. Kicked the door frame. Hasn't felt right since. Just gotta brake the other and they will be even. Lol
