When tapeworm larvae migrate from the intestine to form cysts in tissues such as the brain, muscles, or spinal cord, they can cause a condition known as cysticercosis.1
The symptoms associated with this condition vary depending on the location and extent of the cysts but often include:
- Neurological effects: The presence of cysts in the brain can lead to seizures and mental disorientation.1
- Inflammation: The body’s reaction to the presence of the larvae often results in localized inflammation.1
- Physical manifestations: Cysts may also form under the skin, which can be visible or palpable.1
In other forms of visceral cestodiasis, such as echinococcosis, the symptoms are generally those of a slowly growing tumour, with the specific clinical presentation depending on the organ involved, such as the liver or lungs. It is important to note that while adult tapeworm infections in the intestine may be asymptomatic, the migration of juvenile forms into internal organs poses significant health risks by interfering with normal tissue function.21
