A woman in Australia discovered her headaches were caused by tapeworm larvae in her brain

A 25-year-old woman in Australia discovered she had tapeworm larvae in her brain after suffering from a headache that lasted for more than a week.

The aches were caused by tapeworm larvae that had taken up space in her brain, according to a new study on her case by the The American Journal of Tropical Medicine and Hygiene published on September 21.

The woman, who never traveled overseas, is the first native case of the disease in Australia, the study said. Previous Australian cases of this infection were from immigrants or returning residents who traveled to regions where the disease is endemic to, such as Africa, Asia, and Latin America.

For the past seven years, the woman complained of headaches that would occur two-or three-times a month and went away with prescribed migraine medication. However, her latest headache lasted for more than a week and came with more severe visual symptoms, including the blurring of her central vision. An MRI of her brain led doctors to believe that a tumor might be the cause of her pain, but after operating and removing the lesion, they discovered it was actually a cyst full of tapeworm larvae. After the removal, she required no further treatment.

Tapeworms typically take up residence in human’s intestines, an infection known as taeniasis, and some can pass on their own without medication. The parasite is commonly transmitted when people consume undercooked pork - pigs are often intermediary tapeworm hosts - or come in contact with food, water and soil contaminated with tapeworm eggs.

The best line of defense against similar infection is cooking meat to safe temperatures, washing your hands with soap before eating and only eating food you can $\underline{\text{ensure}}$ was cooked in sanitary conditions.
