R90-R94: Abnormal findings on diagnostic imaging and in function studies, without diagnosis
R90: Abnormal findings on diagnostic imaging of central nervous system
Abnormal findings on diagnostic imaging of the central nervous system represent a range of unusual discoveries made using imaging technologies, such as magnetic resonance imaging (MRI), computerized tomography (CT), or X-rays, that specifically target the brain and spinal cord. These findings could indicate an array of underlying issues, such as injuries, tumors, aneurysms, strokes, or diseases such as multiple sclerosis. Common symptoms associated with these conditions might include headaches, seizures, memory loss, changes in mood or behavior, difficulty in moving, or loss of sensation. Disease progression varies considerably depending on the specific condition. Some conditions might be slow progressing over years, while others could rapidly deteriorate within days or weeks. The nervous system, comprising the brain, spinal cord, and nerves, is the primary body system affected by these conditions.
