World First Identification of Parasitic Worm in Brain

An Australian woman underwent brain surgery only to discover, in what may have been an unbelievable discovery made by neurosurgeon Dr. Hari Priya Bandi, that her expected surgical outcomes did not occur as planned – instead she carefully extracted an 8 cm (3 in) long parasitic roundworm from her head! This incredible find marked the first ever case in human history where live parasites had been discovered inside an individual brain!

My encounters with worms have only ever been limited to my poor gardening abilities, which I find quite terrifying; this isn’t something I deal with regularly,” Dr. Bandi noted in an open conversation with CNN. “When we discovered one moving around among us, my thought was: ‘What is that thing doing here? But it seems alive!’ and soon enough all three of us began feeling queasy.

Unsurprisingly, it turned out to be Ophidascaris robertsi larva, commonly found in carpet pythons but never before documented as human parasite. Dr. Sanjaya Senanayake of this study’s authors was shocked and amazed to encounter such a large worm inside human brain, an unprecedented medical discovery.

At a hospital lab, an employee quickly connected with an animal parasitology expert from a governmental scientific research agency nearby and within 20 minutes had obtained an incredible answer that defied belief.

We were able to send him a live wiggling worm, and he immediately recognized it as what it was,” Senanayake recounted.

Molecular tests confirmed it to be Ophidascaris robertsi, a roundworm typically associated with pythons. As part of their assessment process, medical professionals and scientists involved with this case speculated that an unwitting role played by carpet pythons in spreading the parasite; their feces likely contaminated greens that the patient handled, possibly cross-contaminating with her food or cooking equipment inadvertently.

Senanayake noted the extraordinary nature of this case and expressed her thoughts: “(It) will remain an unforgettable memory.

After being discharged from hospital, she resumed her life but continued under close medical supervision. Although the worm had been extracted, her neuropsychiatric symptoms continued to improve but still persisted as detailed in a journal article.

At first, this connection seemed puzzling to many scientists. While she never directly encountered any snakes, scientists speculate that she may have consumed their eggs through warragal greens found locally and frequently foraged for them for cooking purposes or accidentally transferred the eggs onto food from her hands.


In conclusion, the case of the 3-inch parasitic worm found in a woman’s brain serves as a vivid illustration of how unpredictable and often mysterious human bodies can interact with their environment. This medical marvel, the first of its kind, underscores the necessity of continuous scientific investigation and monitoring in response to emerging health challenges. Though we commend both the patient and medical professionals on their prompt action in responding to this extraordinary event, this bizarre occurrence leaves more questions than answers and points up the dedication and curiosity of science in unravelling its intricate workings. Furthermore, it stands as proof of human resilience even against such mysterious threats to life as perplexing and unexpected invaders.
