Neurocysticercosis is a particularly dangerous complication that can happen if you have an invasive pork tapeworm infection. It can cause headaches, meningitis, visual impairment, seizures, hydrocephalus, and even dementia. In severe scenarios, these complications can be fatal. If larvae travel to your lungs, liver, or other organs, the cysts they form can grow large enough to disrupt how that organ functions. A ruptured cyst is especially problematic because it releases more larvae into your body, which can spread to new tissues. A leaking cyst can also trigger allergic reactions like itching, swelling, hives, and breathing difficulties.
