Meet Allison Ferguson
Allison Ferguson was hard at work finishing her first semester as a high school senior. She was busy
with projects, exams, college applications, a part time job, and running on her school’s cross-country team.
She unexpectedly began experiencing constant headaches, some which caused excruciating pain. Allison visited
her doctor, who thought her headaches were caused by stress. He advised that nothing was wrong and that the
headaches would eventually go away. Yet they continued and were getting worse.
Allison’s parents decided to seek the advice of a neurosurgeon in the family’s home town of Louisville, KY.
An MRI scan revealed a possible microadenoma (small benign tumor) on her pituitary gland. Allison’s neurosurgeon
advised that the tumor was too small to have removed and did not think it was the cause of her headaches. Without
answers, Allison continued to attend school despite having daily headaches. As time passed, her headaches continued
to progress and became more frequent. Another visit to a neurosurgeon, followed by a neurologist, yielded no results.
A few months later, Allison went in for another MRI scan. This time, her doctors found something surprising. The lesion
originally thought to be a microadenoma had grown into something more serious. Doctors diagnosed her with a
cyst, a rare type of cyst believed to originate from remnants of the Rathke pouch. During embryonic development, a Rathke
pouch forms as a depression in the roof of the mouth, eventually losing its connection and rising to the pituitary gland.
In Allison’s case, instead of naturally regressing, the pouch enlarged and formed into the cyst.
Allison’s doctors explained that as the cyst grew it placed pressure on the surrounding structures in her brain, which
was causing her headaches. Because the cyst would continue to grow and cause further complications, it needed to be removed.
The Path to UPMC
One of Allison’s doctors advised her to consult with UPMC to learn more about a cutting-edge procedure being done to remove tumors
through the nose. Allison’s mother, Tanis, turned to the Internet to learn more and discovered the Endoscopic Endonasal Approach (EEA)
that was pioneered by UPMC surgeons. She sent Allison’s medical records to UPMC for review, and within a few days, the Fergusons had
good news. “The doctor called and said that Allison was an excellent candidate for EEA surgery and he was confident he could help her
get back to normal,” explained Tanis. Allison’s surgery was immediately scheduled and the Fergusons packed their bags for the trip to
A team of UPMC neurosurgeons and otolaryngologists drained and removed most of the Rathke cleft cyst through Allison’s nose – using
the EEA technique – immediately relieving the pressure from the surrounding structures of her brain. With this minimally invasive approach,
surgeons were able to partially remove the lesion without disturbing Allison’s brain, blood vessels, or critical nerves. The small piece of
the cyst was not removed in order to avoid damaging the pituitary gland.
A few days following the surgery, Allison was released from the hospital and she and her family returned home to Louisville. She rapidly
bounced back to her everyday routine and is now headache free. “My headaches went away right after I recovered from the surgery,” said Allison.
“When I got home to Kentucky, everything was back to normal. I couldn’t believe it.”
Despite all that happened, Allison was able to finish high school and is now looking forward to attending the University of Kentucky, which
is something her mother thought may not have happened. “If you look at Allison, you would never know that she just had brain surgery,” she said.
“When we first learned of her condition, we didn’t know what to expect. Now, she can do whatever she wants and is so excited to be going away to
school and lead a normal life,” says Tanis. “I’ll miss her, but I know she’ll come visit.”
Our patient stories profile a number of patients who have had minimally invasive brain
surgery at UPMC. Although everyone’s care experience is unique, we hope that sharing
these stories will help other prospective patients and their families better understand
these procedures and their potential benefits.
Allison’s treatment and results may not be representative of all similar cases.
