Horrible case of neurocysticerosis!! We counted the number of active cysts in this patient to be about 65!!! (On these two cuts alone you can see 33!)
Neurocysticerosis is caused by the tape worm taenia solium found in improperly cooked pork that, when ingested, hatch in the stomach, and the larvae crawl thru your intestine, and find a home in your muscles and brain. The resulting inflammation, and possible mass effect/obstruction of the flow of CSF commonly causes headaches and seizures.
We see this quite a bit in Southern California, so when traveling here, don't eat the pork...or drink the water.
Family: Doctor, what's wrong with her?
Me: There are worm cysts in her brain.
Family: oohhhh...the worms!!! She got the worms....
No further explanation was needed, they understood.
