Primary CNS lymphoma in the spinal cord: clinical manifestations may precede MRI detectability.

abstract：:Axial fast FLAIR images of the brains of 40 normal volunteers in four age groups between 16 and 55 years were examined and the number and size of areas of increased white-matter signal recorded. Increased signal in the corticospinal tract region was seen at the level of the internal capsule in all subjects, extending ...
