Visual problems
There are many types of sensory changes related to brain tumors, but the most important of them are visual problems. Patients with brain tumors would sometimes experience total blindness, but it is more common to have a partial vision loss, sometimes only limited to certain quadrants in the visual field. This might not be apparent at first, unless the affected area is large enough, and would be diagnosed after a careful examination of the visual fields. There’s an area just in the middle of the brain called sella turcica, and most brain tumors affecting this area and its surrounding would cause a very particular type of loss of vision.
