Doctors Told a Maryland Great-Grandmother She Had Terminal Cancer. Surgery Revealed Bacteria From a Tooth Infection
A Maryland woman was told she had stage 4 cancer, but brain surgery uncovered a rare infection linked to recent dental work.
The turning point came the instant surgeons opened Lynda Bush's skull. Instead of finding a tumor, they found yellow pus, exposing a very different medical emergency from the terminal cancer her family had been told to expect. What began with a headache and confusion ended with a rare diagnosis, an urgent operation and a family convinced that speaking up changed everything.
She was rushed to the ER after her speech changed
Bush, a great-grandmother from Maryland, was taken to a local emergency room after developing a severe headache, episodes of confusion and slurred speech. Doctors performed a scan and found what was described as a massive lesion on her brain.
The family then received devastating news. ER doctors told them Bush had stage 4 metastatic lung cancer that had spread to her brain, her daughter Amy Walls said. Bush was given steroids to bring down swelling in the brain, but immediate surgery was not considered necessary because doctors believed she was terminal.
Walls said the family felt they were watching her slip away in the hospital bed, with each day seeming worse than the last. Rather than accept that conclusion, they pushed for her to be moved to MedStar Franklin Square Medical Center.
A neurosurgeon looked at the scans and saw something else
At MedStar Franklin Square, Bush came under the care of neurosurgeon Dr. Jugal Shah. After examining her and reviewing the brain images, he was not convinced he was looking at a cancerous tumor.
Shah explained that an infection can sometimes look like a tumor on a scan, and he said what he saw made him strongly suspect that was the real problem. Acting on that concern, he scheduled Bush for surgery right away.
The answer appeared as soon as the procedure began. Shah said yellow pus came out when the brain was opened, confirming his suspicion immediately.
Bush did not have a brain tumor, and she did not have terminal cancer. She had an odontogenic brain abscess, a serious infection in the brain linked to bacteria that usually live in the mouth.
The source was traced back to dental work
Doctors identified the infection as Streptococcus intermedius, a type of bacteria normally found in the mouth. Bush had recently undergone work on a front tooth.
In rare cases, that oral bacteria can enter the bloodstream and end up in the brain. In Bush's case, that is what doctors determined had happened. Untreated, the infection would have been fatal.
The discovery completely changed the course of her care. Instead of preparing for hospice, Bush spent two weeks in the hospital recovering and going through rehabilitation.
She said she likely would not be alive without her family, crediting them with advocating for her care when the first diagnosis did not sit right. Walls drew a broader lesson from the ordeal, saying families need to ask questions, including why a treatment is being given and what it is for.
What looked like the end turned out to be a warning sign from somewhere entirely unexpected: not a spreading cancer, but a rare infection that appears to have started in her mouth and reached her brain.
How a tooth infection can spread
A tooth infection usually starts when bacteria get inside the tooth through decay, a crack, gum disease or an old dental problem. Once bacteria reach the soft tissue in the centre of the tooth, the infection can build pressure and form an abscess.
The mouth is full of bacteria, so untreated dental problems can sometimes spread beyond the tooth into the gums, jaw, face, sinuses or deeper tissues. That spread is more likely if treatment is delayed, the immune system is under strain, or there are other health conditions that make infection harder to fight off.
Why infection can be mistaken for something else
Serious infections can cause swelling, lumps, pain, weight loss, tiredness and changes on scans or imaging. Inflammation can also affect nearby bone and soft tissue. Because of that, an infection can sometimes look like other major illnesses until doctors get a closer look with more tests, drainage, biopsy or surgery.
Not every lump, swollen gland or facial pain comes from a tooth, but dental infection is one possible cause that can be easy to overlook, especially if there is little tooth pain. Problems in the mouth can sometimes show up first as swelling in the jaw, cheek or neck.
What to watch for and when to get help
Get dental or medical advice promptly for persistent toothache, a bad taste in the mouth, swollen gums, facial swelling, pus, fever, or pain when biting. Urgent help is especially important if there is trouble swallowing, trouble breathing, fast spreading swelling, severe weakness, confusion or dehydration.
Practical prevention is simple: brush with fluoride toothpaste, clean between teeth, keep up routine dental checkups, and do not ignore a broken tooth or bleeding gums. If you have a dental infection, do not rely on painkillers alone. The source usually needs proper dental treatment, and antibiotics may be used when a clinician thinks they are needed.
