　　26-year-old Luis Ortiz went to a hospital because of a headache. When doctors examined him, they were shocked to find a tapeworm larva (绦虫幼虫) in his brain and the larva was still alive. The creature had caused a cyst (囊肿) to form inside his head. The cyst was limiting the flow of liquids to different areas of his brain. The situation was so serious that doctors said they had to perform an emergency operation to remove the larva.

　　Luis Ortiz was a student at California State University. He began experiencing headaches in late August. But he did not think the headaches were serious. In September, he visited his parents in another city. That was when the pain got worse. His mother saw Ortiz throwing up (呕吐) so she took him to a hospital emergency room. Ortiz said he was shocked and he couldn’t believe something like that would happen to him. The doctors saved Ortiz’s life. However, the operation also affected him. Ortiz had to drop out of school and move back home. He is not permitted to work or drive a vehicle.

　　Tapeworms usually infect a person’s intestinal (肠的) system. In rare cases, they infect the brain. Doctors were surprised and suspected Ortiz ate something containing the tapeworm. You can get a tapeworm from food that is unclean, and infected with tapeworm eggs. People can get them from eating infected, uncooked pork or pork that is not cooked thoroughly. Another type of tapeworm can infect beef. The U.S. Centers for Disease Control and Prevention says the U.S. has about 1,000 reported cases of tapeworms each year and tapeworms are more common in developing countries with poor public health systems.
