Travelers Urged To Take Warning After Spike In Parasites!

Doctors opened a woman’s skull looking for a tumor and instead found a live snake parasite crawling in her brain.

Story Snapshot

A 64-year-old Australian woman had an 8-centimeter roundworm removed from her frontal lobe, still wriggling.
The parasite, Ophidascaris robertsi, normally lives in carpet pythons and had never before been found in a human.
Her year-long mystery illness with lung and liver lesions was likely the worm’s larvae migrating through her body.
Doctors suspect she was infected by eating wild warrigal greens contaminated with python droppings near her home.

The day surgeons met a live worm in the human brain

In June 2022, a neurosurgeon in Canberra slid instruments into the frontal lobe of a 64-year-old woman, expecting to biopsy what looked like a standard brain lesion on her scan. Instead, they saw something move. They pulled out a red, 8-centimeter roundworm, still alive and wriggling on the surgical tray. Genetic testing later showed it was Ophidascaris robertsi, a parasite usually found in carpet pythons, never before seen inside any mammal’s brain.

The find stunned the team, but for the patient, it explained nearly 18 months of misery. Her ordeal began in January 2021 with abdominal pain, diarrhea, dry cough, and night sweats. Scans showed strange lesions in her lungs and liver, and blood tests revealed sky-high eosinophils, a type of white blood cell that often rises with parasites. Despite this clue, no worm was found in earlier samples, and she was instead treated for a rare blood disorder with heavy steroids.

From “autoimmune mystery” to migrating parasites

The woman’s doctors first diagnosed hypereosinophilic syndrome, a condition where the body churns out excess eosinophils and can damage organs. They used strong immunosuppressive drugs to control the supposed autoimmune process. That decision made sense at the time, but it likely gave the parasite more freedom to roam. Case investigators later concluded her pattern of lung, liver, and spleen lesions matched larva migrans, where worm larvae wander through organs and inflame tissues.

As months passed, her symptoms shifted from gut and chest problems to the mind. She developed forgetfulness, depression, and changes in mood strong enough to push her back to doctors. A brain magnetic resonance imaging scan finally revealed a 13-millimeter lesion in her right frontal lobe. Surgeons went in to remove what they thought was an inflamed cavity or tumor. Instead, they met the python parasite face to face. This sequence shows how easily rare infections can masquerade as autoimmune disease when lab tests fail to catch the invader.

How a python parasite jumped from swamp to skillet

The obvious puzzle was how a snake worm ended up inside a woman who had never handled snakes. Carpet pythons carry Ophidascaris robertsi in their gut, shed its eggs in droppings, and use small mammals as intermediate hosts in nature. The woman lived near a lake in New South Wales, in known python habitat, and often foraged native warrigal greens to cook at home. Researchers believe she ate greens contaminated with python feces, swallowing microscopic eggs that hatched into larvae in her intestine.

From there, doctors think the larvae punched through the bowel wall, rode the bloodstream, and lodged in organs like the lungs, liver, and spleen before one finally invaded her brain. This route fits the scattered lesions seen on her scans and the long, shifting symptom trail before surgery. There is no direct proof from testing the exact greens she ate, but the carpet python life cycle and her foraging habits make this explanation more convincing than random chance. It is a classic example of a zoonotic disease, where an animal infection crosses into humans.

Treatment, recovery, and the quiet lesson for everyday life

Once the worm was out, doctors still had to kill any remaining larvae lurking in her body. They treated her with albendazole and ivermectin, two long-standing antiparasitic drugs, combined with carefully managed steroids. Follow-up visits over six months showed her blood counts normalizing and her mood and memory steadily improving. She did not suffer major neurological disability, a near miracle given a live parasite had been tunneling through her frontal lobe.

This case grabbed headlines because “brain worm” stories sell clicks, and some outlets even twisted it into talk of tapeworms and dozens of parasites, far beyond the facts. The real story is quieter and more practical. One rare snake parasite used a common human habit—gathering wild greens—plus a misdiagnosis to slip past modern medicine. That should nudge public health leaders to offer clear, simple advice: if you forage near wildlife, wash produce well, keep animals’ droppings away from food, and respect the unseen risks in nature.
