A lot of the Doctors I work with are left wing atheists so this is impossible in their book.
I’m not sure how they would call it impossible, because nothing theistic was invoked. They’d call it a rare misdiagnosed case, misdiagnosed due to unusual factors.
What they might call impossible is any way that God could be reached by prayer and brought to bear thereby in a healing way on the patient.
A similar brain problem happened to me last year. I checked into one hospital with headaches and a bad brain scan. After four days at the hospital, the doctors sent me home hoping the blood in my brain case would absorb. (It wouldn't have and I would probably have passed away.)
My primary care physician did not accept the diagnosis. He had the personal cell of a neurologist from Barrows Clinic on his phone. He called her and arranged to get me seen the next day. The neurologist immediately had me checked into their hospital, St. Joseph's in Phoenix. Surgery occurred the next day after a completely different diagnosis.
Along the way, I had several events of drifting in and out of conscienceness. They pounded on my chest to get a response. Two different hospital personnel informed my wife that they thought they had "lost me".
After several surgeries and a month in the hospital, my primary care physician informed my wife and I that: "Anyone who doesn't believe that God intervened just doesn't understand!"
My athiest doctor brother-in-law wrote it off as good doctoring.
We found out later through a different source that my primary had had a patient with the same condition during the prior year. That is why he had the neurologist's cell number, why he was familiar with my condition, and why he was able to get me into Barrows in time.
