Doctors thought a 60-year-old man had metastatic brain cancer after scans revealed multiple tumors \u2013 but further testing revealed a shocking diagnosis<\/a>.<\/p>\n

The Spanish man, who was not named, was found to have a parasitic tapeworm larvae lodged in his brain \u2014 a case of neurocysticercosis, a parasitic infection<\/a> of the central nervous system caused by the pork tapeworm (Taenia solium).<\/p>\n

The patient, a lifelong resident of Castell\u00f3n, Spain, had not traveled to any regions where the disease is endemic, according to the case report published in the CDC journal Emerging Infectious Diseases.<\/p>\n

The man had initially come to the hospital after suffering two weeks of progressive headaches and mild behavioral changes.<\/p>\n

However, whole-body scans, a colonoscopy and specialized imaging failed to identify cancer anywhere in the patient’s body, the case report stated.<\/p>\n

When doctors performed a more detailed MRI, they discovered several fluid-filled cysts in the brain, some of which contained the head of a tapeworm. A blood test confirmed the diagnosis of neurocysticercosis.<\/p>\n

The man was treated with a combination of albendazole and praziquantel (two antiparasitic medications<\/a>), as well as corticosteroids to reduce inflammation. He successfully recovered with no complications, according to the case report.<\/p>\n

The authors suggested that the patient may have gotten the infection after accidentally ingesting microscopic tapeworm eggs years earlier.<\/p>\n

The exposure may have occurred while working a construction job with migrant coworkers from regions where neurocysticercosis is endemic.<\/p>\n

People can catch the pork tapeworm in two different ways. Eating undercooked infected pork usually leads to an intestinal tapeworm, but accidentally swallowing the parasite’s eggs \u2014 typically through food or water contaminated with feces \u2014 can send the larvae into the bloodstream, where they may form cysts in the brain<\/a> and other organs. This can cause the disease the patient in the case report acquired.<\/p>\n

As this was just a single case, the source of transmission<\/a> could not be proven, the researchers acknowledged, and the findings cannot be generalized to a wider population. The report shows that there is a possibility of local transmission in non-endemic settings, but cannot establish how often this occurs.<\/p>\n

In the United States, less than 2% of neurocysticercosis cases are considered domestically acquired, according to the case report.<\/p>\n

A prior systematic review identified only 18 confirmed locally acquired cases in Western Europe between 1990 and 2011.<\/p>\n

“Our case emphasizes that the absence of travel history should not preclude NCC from the differential diagnosis of multiple ring-enhancing brain lesions, even in regions where metastatic cancer<\/a> is statistically much more likely,” the researchers concluded in the case study.<\/p>\n

Detecting the worms earlier could have prevented “unnecessary invasive oncologic procedures and led to prompt, targeted antiparasitic therapy,” they added.<\/p>\n
