A woman who kept falling over and felt tingling in her legs was shocked to discover the cause.The 35-year-old ended up in hospital where medics scanned her spine. To their surprise, they found tapeworm larvae wriggling around the patient’s vertebrae. The French woman, who is not named, arrived at hospital complaining of suffering what felt like “electric shocks” running down her legs. She felt weak, and had experienced a number of falls. A scan showed a lesion at her 9th vertebra – in the middle of her spine. Surgeons investigated and found the lesion was in fact tapeworm larvae, caused by an infection of Echinococcus granulosus – a small tapeworm found in dogs and some farm animals.
