Tell me you’re not a doctor without telling me you’re not a doctor:

“frequently, radiologists spend hours on the phone getting approval”

[Ian Mark @iantmark]

Such important work! Thanks for leading!

[Andrew L Callen MD @AndrewCallenMD]

Sacral dural tears in #SIH are probably under-recognized.

Why?
Because the sacrum often isn’t scrutinized, or sometimes even included in the field of view on routine spine imaging.

In a new multicenter @AJNR study we found:

• Sacral leaks often produce isolated sacral CSF collections
• Image-guided patching can lead to meaningful clinical & imaging improvement
• Longitudinal imaging suggests some lesions mimicking “Tarlov cysts” may actually represent chronic or partially healed leaks

Encouraging to see multicenter collaboration continue to emerge in SIH imaging/treatment research.

At what level and side do CSF-venous fistulas occur? @MayoRadiology @issclsociety @spinalCSFleak

Careful evaluation for SIH is crucial before considering Chiari decompression in patients with tonsillar herniation.
Our new publication @iantmark describes patients with SIH who were initially treated with Chiari decompression.

Our latest work on #Pituitary imaging. @JamieVanGompel @MayoRadiology

[Parnian habibi @parnian_habibi]

You’re looking at a sellar/suprasellar mass with calcification and think, it must be craniopharyngioma.
But it’s time to pause.
Our @iantmark study found that 22% of pathology-proven giant pituitary macroadenomas showed peripheral calcifications on CT.
