Brain MRI Results Show Abnormalities

Tim's brain MRI came back showing abnormalities in his cerebrum. This could be from a number of sources. To list them in order from most likely to least likely: 1) Leukemia in the brain tissue 2) An infection in the brain tissue 3) Inflammation 4) other malignancy. Unfortunately, the MRI cannot tell the doctors which of these four is the cause of the abnormalities. They do believe that whatever is causing the changes in his brain is the cause of his mental confusion.

In order to try to determine the cause of the problem, the doctors have ordered a spinal tap and and a MRS (magnetic resonance spectroscopy - a fancy MRI) of his brain and his spine. If those tests are inconclusive, they will do a biopsy of some the affected brain tissue. The treatment for each of the possible causes is very different, so it is important to know what we're treating before we do anything.

They are moving Tim to a new room right by the nurses station later today. I believe we will be in 1587 by the end of the day. If Tim has the biopsy, we will be moving yet again. He'll spend one day in the neuro ICU, a couple in their step-down unit and then move back to the cancer center into a new room.
