I wish this article talked about how they are treating? They just said she is doing well

With the actual worm they pulled it out and presumably cleaned up the bit of her brain where it resided.

For the rest I guess they made her take something that kills nematode parasites, and some strong anti inflammatories?

said the patient needed to be treated for other larvae that might have invaded other parts of her body, such as the liver. But given no patient had ever been treated for the parasite before, care was taken. Some medications for example could trigger inflammation as the larvae died off. Inflammation can be harmful to organs such as the brain, so they also needed to administer medications to counteract any dangerous side-effects.

Probably something like this. There is an entire class of drug rarely needed that does exactly this thing, but won’t kill a fully formed spawn of an egg that wandered into the bloodstream. Antiparasitic drugs are rough, but save thousands of lives per years where this type of parasite is an issue. This case is exactly why doctors may ask if you’ve traveled recently, and to where.
