2024_06_18 Neurocysticercosis, Annotated

 

What follows is the document of annotations that I shared with a neurosurgeon on June 18, which I reference in other posts.

Neurocysticercosis suspects

To respect your time, I’ll only share the clearest examples.

Midbrain/spinal cord

The blip on coronal view here can be appreciated over multiple frames, many which show possible centrally adjacent edema. The second blip unfortunately only exists in this sagittal frame… couldn’t be an artifact? 

Basal ganglia level

If you look at enough examples of Neurocysticercosis imaging, you’ll note that the pathognomonic “cyst with dot” sign is not really just a single eccentric dot, and can often be observed as a distinctive big dot/ little dot pair.

[I suspect the 5mm VR space we talked about is a cysticercus because 1.Two dots, and 2. (appearance of) non-CSF intensity (cysticerci in the same brain can be at different stages of breakdown).] 

The two in yellow circles are of course the better candidates.

4th ventricle

Racemose cystic grouping? Restricted diffusion?
