英國一華人在08年開始感覺頻繁頭痛，聞到異味。看醫生後做MRI發現他的大腦內有一條絛蟲。這個絛蟲還自由自在地在腦子裏到處亂跑。直到2012年才手術拿了出來。這個絛蟲沒有嘴巴，推測是通過身體皮膚吸收營養。可能是他回中國期間曾用生青蛙肉敷在眼睛上治療眼疾導致的。

......
But four years later the 1cm-long worm was finally found after scientists at St Thomas’ Hospital in London took a biopsy of his brain.
By the time surgeons were able to extract the parasite, the worm had travelled 5cm to the right side of his brain. Eggs from the parasite had also feasted on his brain matter.
The tiny tapeworm, Spirometra erinaceieuropaei, was identified by a team of scientists led by Dr Hayley Bennett, from the Wellcome Trust Sanger Institute, which mapped its genome.
It has only been reported 300 times in the last 60 years, the scientists said. It is rare but most commonly found in South East Asia, China and Japan.
The rare worm was of a type never before found in the UK but it is believed that it can be caught by eating infected food or via a Chinese medical remedy for sore eyes that includes raw frog.
As well as the Chinese medicine risk, it is also believed to be transmitted by eating infected crustaceans from lakes or eating raw meat from reptiles and amphibians, they said.
......因為太罕見，英國醫生把絛蟲基因測序了。發現這個絛蟲DNA是普通絛蟲的10倍，接近人的1/3。隻出現在東南亞。靠通過皮膚吸收大腦的脂肪酸為生。因此還發了篇論文。The genome of the sparganosis tapeworm Spirometra erinaceieuropaei isolated from the biopsy of a migrating brain lesion
