This reminded me of a Dr House episode where the patient somehow ingested tape worm eggs, which managed to make their way into the brain, thigh muscle etc... through blood, then hatch there.

Looks like it is referred to as Neurocysticercosis [0].

The parasite does not necessarily chose where it might end up, so it is up to luck. The victim probably ingest a bunch of eggs, which will find their way into different parts of the body, with different level of survivability. The brain does look like a cosy place to survive.
