Since late September last year, Mr. Lu, a 54-year-old citizen of Nanning, has always felt constant swelling and pain in his head, and has also experienced symptoms such as general weakness and loss of appetite.
Mr. Lu came to the Fourth People's Hospital of Nanning City for examination, and the doctor found that there were multiple calcified lesions in his skull, and even a puncture deformity occurred, and there may be cysticer parasitism in the skull.
After that, Mr. Lu underwent surgery. The doctor found the lesion in Mr. Lu's skull and pulled the brain cysticer worm out of the brain little by little along with the envelope. Mr. Lu underwent a follow-up examination after the operation, and the lesions completely disappeared, and the symptoms such as headaches were significantly improved.
According to the attending physician, Mr. Lu's neurocysticercosis is caused by the larval stage of tapeworm (cysticercosis) in the brain tissue. Mr. Lu was infected with cysticercosis precisely because he ate uncooked pork with cysticercles.
When the pig tapeworm eggs enter the human body through the mouth, develop into six hooked larvae in the intestinal lumen, penetrate the intestinal wall through the digestive tract into the mesenteric vena, and then circulate through the blood to reach the meninges, brain parenchyma and intraventricular caused by cysticercosis, the process generally takes 2-3 months.
Patients with cerebral cysticercosis have serious damage to brain tissue and brain centers, manifested by headaches and weakness, and in severe cases, there may be seizures, increased intracranial pressure, mental disorders, and even blindness.
The pathogenesis of brain lesions caused by cysticercosis mainly includes: (1) compression and destruction of peripheral brain tissue by cysticercosis; (2) brain tissue allergies and inflammation caused by heterogeneous proteins; (3) cysticercosis obstructing the cerebrospinal fluid circulation pathway and causing increased intracranial pressure.
Neurocysticercosis is a chronic parasitic disease caused by infection with tapeworm in pigs. Adult tapeworms parasitize in the human intestine as intestinal tapeworm disease, and their larvae parasitize in human subcutaneous tissues, muscles, brains and other organs as cysticercosis.
In addition to directly eating uncooked pork, raw and cooked food cutting board sharing will also lead to the human body to eat insect eggs by mistake, while purchasing meat should be purchased from formal channels, do not buy untested pork, when the body has symptoms of discomfort should go to the hospital as soon as possible to avoid further damage to the function of human organs.
When there is a case of accidentally eating undercooked food, parasite detection should be carried out in time to check whether the body is infected with parasites. Some parasites have a long incubation period and physical symptoms are not obvious, and regular parasite detection and screening can be more rapid and effective to monitor the infection and prevent it before it happens.
