Kid Captain Ellie Walker faced rare, aggressive brain cancer with courage and resilience
Clinton, Iowa 4-year-old celebrated her remission before cancer returned just weeks later
Ellie Walker was 3 years old when she was diagnosed with an extremely rare and aggressive form of pediatric brain cancer at University of Iowa Health Care Stead Family Children’s Hospital. She experienced more than a year of radiation and chemotherapy as well as countless hospital stays, blood and platelet transfusions, surgeries, scans, lumbar punctures, and other difficult treatments and side effects.
This spring, Ellie, then 4, celebrated what everyone believed would be the end of her treatment, and later her cancer was considered in remission. In late spring, the family learned that Ellie had been selected to be a member of the 2026 Kid Captain team.
Sadly, Ellie’s cancer returned in early summer, and she passed away on July 6.
Now in its 17th season, the Kid Captain program will continue to honor the life of Eleanor “Ellie” Walker as Honorary Kid Captain during the Hawkeyes’ Nov. 7 game at Northwestern.
Ellie’s story is below.
Max and Miranda Walker, of Clinton, Iowa, remember Ellie as a bright light whose smile could warm any room. Known for her fiery red hair, gentle heart, and caring nature, she brought joy to everyone fortunate enough to know her.
They say that in her four years of life, Ellie touched countless hearts with her strength, kindness, and sassy spirit. She loved Disney princesses, especially Ariel and Merida, enjoyed building sandcastles on the beaches of Destin, Florida, and cherished quiet afternoons snuggled on the couch watching Disney movies. Above everything else, she adored spending time with her family, especially her big brother, Theo, who was her best friend.
Ellie was born healthy but began experiencing persistent headaches and vomiting when she was 3 years old. After testing at her local hospital, her family learned she had a mass in her brain. She was immediately transferred to University of Iowa Health Care Stead Family Children’s Hospital, where doctors diagnosed her with stage 4 pineoblastoma — an extremely rare and aggressive pediatric brain cancer originating in the pineal gland.
Fewer than 100 cases are diagnosed in the United States each year. In Ellie’s case, the cancer had also spread to her spine.
Within days, neurosurgeons at Stead Family Children’s Hospital placed a shunt to relieve pressure on her brain before performing a 13-hour surgery to remove as much of the tumor in the pineal region as possible.
While recovering from surgery, Ellie’s care team at Stead Family Children’s Hospital readied for the post-surgery treatment plan, which would include proton radiation and chemotherapy to start. Because the aggressive cancer had spread, Ellie was treated at another hospital that offered proton radiation, and scans there showed the cancer had already returned.
“It opened our eyes to show how aggressive it was and how much of a fight it would be for this little 3-year-old,” Miranda recalls.
Ellie underwent 30 rounds of proton radiation before returning to Iowa City to begin six intensive cycles of chemotherapy. Over the next year, she endured countless hospital stays, blood and platelet transfusions, surgeries, scans, lumbar punctures, hearing loss from chemotherapy, feeding tubes, medications, and rehabilitation.
Her parents say that despite everything, Ellie rarely let cancer define her.
She continued to smile, laugh, play, and brighten the halls of Stead Family Children’s Hospital. She would tell everyone, “I’m going to be brave like Merida,” inspiring nurses, physicians, pharmacists, and other caregivers who became like family to the Walkers during their 14 months at the hospital.
Early in 2026, new MRI findings raised fears that the cancer had advanced despite treatment. Additional biopsies and testing, however, showed it was just a complication and doctors continued treatment.
"They [Ellie's oncology team] get familiar with your schedules, and they really become your second family. There was never one point that I felt alone."

In April, Ellie celebrated what everyone hoped would be the end of her cancer journey. Nurses, pharmacy staff, doctors, and many others attended her end-of-treatment party.
“They were in tears,” Miranda recalls, noting that the oncology team had become like family. “They get familiar with your schedules, and they really become your second family. There was never one point that I felt alone.”
In spring 2026, the family was given the news that Ellie was in remission after treatment ended.
Sadly, by early summer, everything changed again.
Ellie suddenly began struggling to walk and rapidly lost her balance. Imaging revealed that her cancer had aggressively returned throughout her brain and spine. Doctors immediately placed a small device and tube, called an Ommaya reservoir, under her scalp to deliver chemotherapy directly to her brain. They also revised her shunt and began every available treatment in hopes of slowing the disease.
Despite the efforts of her medical team, the cancer continued to rapidly progress. Within weeks, Ellie lost the ability to walk and communicate. Her family remained by her side every moment, filling her days with love, music, Disney movies, and the unwavering support that had carried them through every challenge.
On July 4, surrounded by family on the 11th floor of Stead Family Children’s Hospital, Ellie experienced one final Hawkeye Wave from outside Kinnick Stadium. Two days later, she passed away peacefully surrounded by those who loved her most.
Although her life lasted less than five years, Ellie’s impact reached far beyond her age.
Even after her passing, Ellie continues to inspire hope as a 2026 Iowa Hawkeye Kid Captain, ensuring her story of courage, resilience, and unconditional love will continue to touch future generations.
“She’s the strongest person I’ve ever met,” Miranda says.
For Max, Miranda, and Theo, sharing Ellie’s story is a way to celebrate who she was and the lasting impact she had on their family.
“It means so much to us,” Max says. “It gives us the opportunity to celebrate the incredible strength, courage, and joy she brought to so many people.”
Through her family’s decision to continue to share her story, Ellie’s spirit will remain part of the Kid Captain community and continue to inspire others.
Meet Kid Captain Charley Rasmussen
Kindergarten was hard for Charley Rasmussen. She often felt sick, lost 20 pounds in a single month, and experienced severe pain that sometimes woke her at night. As her health declined, her family searched for answers. In January 2018, Charley was diagnosed with Addison’s disease, a rare condition in which the body does not produce enough essential hormones.
Meet Kid Captain Kaelyn O’Brien
When Kaelyn O’Brien couldn’t walk down the hallway and her speech became slurred one morning, her parents thought their 11-year-old daughter was having a stroke.
Meet Kid Captain JJ Ward
JJ Ward underwent emergency bowel surgery less than a day after he was born. Diagnosed with meconium ileus, surgeons removed one-third of his small intestine and inserted a temporary feeding tube. The obstruction can serve as a sign of cystic fibrosis, and tests confirmed that JJ had the disease.
Meet Kid Captain Eliana Gaul
Roger and Ashley Gaul were planning an afternoon of fun following a doctor’s appointment and ultrasound. But their joy quickly turned to heartache: Prenatal tests indicated their baby, Eliana, would be born with spina bifida, a condition in which the spinal column and membranes around the spinal cord don’t close completely during the first month of pregnancy.
