I Thought My Son Was Allergic to Cow’s Milk, Reality Was My Worst Nightmare
Finley, a toddler from the United Kingdom, was diagnosed with an aggressive brain cancer known as atypical teratoid rhabdoid tumor (ATRT) after months of recurring vomiting and misdiagnoses. His mother, Melinda Garratt, reports that the child’s symptoms were initially attributed to common childhood ailments, including cow’s milk allergy and stomach bugs, before a CT scan at the Royal Victoria Infirmary identified the tumor at the base of his brain.
The Path to Diagnosis
The diagnostic process for Finley lasted several months, during which he was repeatedly examined at various medical facilities. According to Melinda Garratt, early symptoms included projectile vomiting and sudden skin rashes. Medical professionals at different stages suggested the child might be adjusting to cow’s milk, suffering from a stomach bug, or experiencing “slapped cheek syndrome.”
The situation escalated when Finley began vomiting blood and experienced what appeared to be a seizure. Despite these developments, previous clinical encounters resulted in discharges with explanations such as constipation or potential nosebleeds. It was only upon transfer to the Royal Victoria Infirmary—where he was initially placed on a neurological ward due to a lack of space—that a medical team identified the neurological nature of his symptoms and performed the necessary imaging.
Finley’s diagnosis was reached only after his sixth visit to medical facilities, where he was repeatedly dismissed with explanations ranging from dietary sensitivities to minor viral infections.
Treatment and Recovery
Following the discovery of the tumor, which was situated at the top of his spine near the brain’s base, Finley underwent surgery to remove the mass. Surgeons successfully excised the entire tumor. However, the subsequent pathology report confirmed the diagnosis of ATRT, a rare and aggressive form of cancer.

The treatment plan involved an intensive regimen of high-dose chemotherapy, multiple blood transfusions, and the surgical insertion of a reservoir into his head. Melinda Garratt notes that the process was characterized by frequent hospitalizations and complications, but Finley eventually finished his treatment and rang the hospital bell earlier this year. His most recent scans have returned clear results.
The challenges faced by the family underscore the difficulty in diagnosing rare pediatric brain tumors, which often present with non-specific symptoms like vomiting. The reliance on parental intuition to persist in seeking further medical evaluation remains a critical factor in identifying time-sensitive conditions when initial screenings prove inconclusive.
What Happens Next
While Finley is currently in remission, the clinical prognosis for ATRT involves a high risk of relapse, particularly within the first two years post-treatment. The family is currently following a strict surveillance schedule, which includes undergoing scans every three months to monitor for any signs of recurrence.
Analysts of pediatric oncology cases generally expect that long-term monitoring is necessary for patients with aggressive tumor types. For the family, the immediate future involves balancing the return to a normal, active life for the two-year-old with the ongoing anxiety associated with regular oncology follow-ups.
Frequently Asked Questions
What is ATRT?
ATRT, or atypical teratoid rhabdoid tumor, is a rare and aggressive form of cancer found in the brain and spinal cord.
What were the warning signs that indicated something was wrong?
Finley experienced frequent morning vomiting—even after sleeping through the night—and eventually began vomiting blood, alongside the sudden appearance and disappearance of rashes.
Why is the family continuing to have regular scans?
Because ATRT has a high risk of relapse, particularly within the first two years, regular imaging is required to ensure the cancer has not returned.
How do you maintain hope while navigating the uncertainty of a medical diagnosis that carries a high risk of relapse?
