A woman suddenly felt a severe headache. The nurse took a closer look and immediately ran to get the doctor.
What started as a bout of headaches for a Texas mother of two turned out to be something far more serious than she could have imagined.
After suffering from severe headaches for more than a year, 31-year-old Yadira Rostro of Garland, Texas, was diagnosed with tapeworm larvae growing inside her brain. She later discovered that the parasites were the root of her misery.
Beyond the excruciating headaches, Rostro also suffered from frequent vision problems. Her condition eventually progressed to the point where she could barely see clearly in any direction.
In early September, she underwent surgery at Methodist Dallas Medical Center. During the procedure, doctors discovered and removed between six and eight tapeworm cysts from her brain.
According to Dr. Richard Mayr, a neurosurgeon at Methodist Dallas Medical Center, the cysts were surrounded by transparent sacs and looked somewhat like eggs. Inside each sac was a small tapeworm larva.
Doctors believe Rostro may have come into contact with the parasite during a trip to Mexico approximately two years earlier, although she was never able to confirm exactly how she became infected.
It was suggested that the parasite may have entered her body through food or water contaminated with fecal matter. Normally, tapeworms pass through the digestive system. In Rostro’s case, however, the parasite’s larvae apparently entered her bloodstream and eventually reached her brain.
The larvae continued to develop there, causing fluid to accumulate around the affected area. This buildup was believed to be responsible for her severe headaches and vision problems.
Tapeworms are parasitic flatworms that commonly live in the intestines of humans and animals. People can become infected by consuming food contaminated with tapeworm eggs, eating undercooked meat, or coming into contact with contaminated fecal matter.
In many cases, people infected with tapeworms may not immediately realize anything is wrong. Symptoms can include fatigue, unexplained weight loss, diarrhea, abdominal pain, nausea, and other digestive problems.
However, when tapeworm larvae reach the brain, the condition can become far more serious. This form of infection is known as neurocysticercosis and can cause headaches, seizures, vision problems, and other neurological symptoms.
When Rostro’s headaches became increasingly severe, she eventually sought medical attention. Doctors initially suspected that she might have a tumor because of the location and appearance of the abnormalities on her brain scans.
But when surgeons examined the area more closely, they discovered something far more unusual.
During the operation, doctors found several cysts containing tapeworm larvae near the base of her brain, close to the brain stem. Rostro was placed under anesthesia, and surgeons made an incision at the base of her skull. They carefully separated the surrounding tissue and used a microscope to remove the cysts.
The procedure was completed within minutes, and the parasites were successfully removed.
Dr. Mayr said he had never encountered anything quite like it. He described the discovery as extremely unusual but was relieved that the medical team was able to identify the problem and treat Rostro before it caused permanent damage.
Following the surgery, Rostro began a slow but steady recovery. She was relieved to learn that she had survived the ordeal and was not expected to suffer any long-term consequences.
Her case is not completely unique, however.
Doctors in Australia were also shocked when they discovered tapeworm larvae inside the brain of a woman who had suffered from severe headaches for years.
The Australian woman had experienced splitting headaches for approximately seven years. She was initially treated for migraines, but her symptoms continued.
After experiencing another particularly severe headache, she underwent an MRI scan. The images appeared to show what doctors believed could be a tumor, so she was referred for further testing.
When surgeons operated, they discovered that what appeared to be a tumor was actually a cyst containing tapeworm larvae.
The woman had never traveled outside Australia, making the discovery even more surprising. Doctors believed she had unknowingly swallowed tapeworm eggs that had been released by an infected carrier.
She eventually made a full recovery.
These cases demonstrate how unusual, but potentially serious, tapeworm infections of the brain can be.
According to the World Health Organization, neurocysticercosis is an important cause of epilepsy in many parts of the world. The condition occurs when people accidentally ingest microscopic eggs from the pork tapeworm, Taenia solium.
The infection can be prevented through proper hygiene, safe food preparation, and access to clean water. Eating undercooked pork, drinking contaminated water, or coming into contact with fecal matter from an infected person can increase the risk of infection.
Neurocysticercosis is uncommon in wealthier countries such as the United States, Canada, much of Europe, Japan, and Australia. However, cases can occur among immigrants and travelers who have spent time in regions where the parasite is more common.
For Yadira Rostro, what began as unexplained headaches and increasingly severe vision problems ultimately led to a shocking diagnosis.
She had never imagined that tiny parasites could be growing inside her brain.
Thankfully, doctors discovered the problem in time, removed the cysts, and gave her a chance to return to a normal, healthy life.
