The first series of images helps to orient you to what you are looking at.  The first two are coronal slices, that is, as if the head were “cut” to expose the front versus back of the brain.  The top image shows near the front of the brain – note the ventricles. The second image is to the back of the head, note the cerebellum.

The next two are in the axial plane, showing a “slice” as if the top of the head were removed. In slide 3 you can see the eyes and in the bottom slide you can see the teeth/jaw.

The next images show “slices” through the tumor.  I selected two images in each of the coronal and axial planes.  Note the scale which is on the right hand side. At its largest, the tumor (the large white mass towards the left of your screen) is about 3 cm.  There are 2.54 cm per inch.

The patient was moving out of the area; the recommendation was for tinnitus treatment closer to her new home.

It’s interesting that this tumor is not impinging at all on the right side of the brainstem, yet that ear has some hearing loss.  Stereotactic radiation should be quite focused – it should not have damaged any right side structures.
