A 63-year-old Taipei man who consulted a doctor about swelling above his right eye found out that it was caused by a 6cm long parasitic worm that had burrowed into his head, a Chinese-language newspaper reported yesterday.
The man, identified only by his family name Huang (黃), thought at first that the painless swelling was the result of a mosquito bite, according to Yang Hsi-ming (楊熹明), from the ophthalmology department at Cardinal Tien Hospital. But a month later the swelling still hadn't gone away, and became painful when the man squeezed it. Huang then decided to visit the doctor.
Huang's eyes showed no abnormal signs, and so Yang first thought it might be an inflamed sebaceous gland, according to the report. After giving Huang local anesthetic, Yang cut the swelling open and prepared to clean it.
To his surprise, he found very little granulation tissue in the swelling, but instead saw a white ball. When he used a pincer to pull it out, he found the worm.
