68 yo female with vertigo. T2-dark mass w/peripheral enhancement and "Black-out" phenomena in the right aspect of the brainstem, most likely due to susceptibility artifact. Slightly T1 shortening also noted. Caseating tuberculoma is top in the DDx. #neurorad #infectiousdisease

1/Time is brain! But what time is it? If you don’t know the time of stroke onset, are you able to deduce it from imaging? Here’s a thread to help you date a stroke on MRI!

The H-sign refers to increased T2-signal of the central gray matter of the myelum (with some faint T2-increase in the surrounding white matter). It's a pattern most suggestive of MOGAD-myelits, but can also be seen in (minority of) NMOSD & idiopathic transverse myelitis. #MedEd

1/Nothing is more CENTRAL to reading an MRI than finding the CENTRAL sulcus? How do YOU find it? Are you just using gestalt when you say “frontal” or “parietal”?  Time to recenter your search pattern with this thread on how to find the central sulcus on a brain MRI!

Finally, after significant intrathekal pressurization, the CVF was clearly and continuously visible in this case.

Is pressurization useful for CSF-venous fistula detection? A technical note and illustrative case by @Niklas_Luetzen et al. provided the importance of intrathecal pressurization. @ZanderCharlotte @Uniklinik_Fr @spinalCSFleak #MedTwitter Read here: journals.sagepub.com/doi/abs/10.117…
