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.
