Complications
By Mayo Clinic staffThe consequences of tapeworm infection can vary, depending on what species of tapeworm you're infected with.
Intestinal infection complications
Generally, intestinal tapeworm infections have little or no complications. But if the tapeworms grow large enough, they can block your bile duct, appendix or pancreatic duct, causing problems for those organs.
Invasive infection complications
Invasive infections have a greater likelihood of developing complications, including:
- Brain and central nervous system impairment. Called neurocysticercosis, this especially dangerous complication of invasive pork tapeworm infection can result in headaches and visual impairment, as well as seizures, meningitis, hydrocephalus or dementia. Death can occur in severe cases of infection.
- Organ function disruption. When larvae migrate to tissues or organs in your body, they develop into lesions or cysts. Over time, they grow larger, and sometimes their size can disrupt organ function, or they can grow so large that they rupture. In other cases, cysts put pressure on nearby blood vessels, hindering circulation or causing blood vessels to rupture. Surgery or organ transplantation may be needed in severe cases.
