Very Early Demonstration of Secondary Pyramidal Tract Degeneration by Computed Tomography Stroke 25:2287-2289, Kazui,S.,et al, 1994 See this aricle in Pubmed Article Abstract Although initial CT did not detect any hypodense areas along the left pyramidal tract below the hematoma,ill-defined areas of deceased density appeared in the posterior limb of the internal capsule,cerebral peduncle of the midbrain,and pontine base of the left side on day 13 after the stroke.These areas became well demarcated on day 22 and persisted thereafter.An extensive hematoma can interrupt the pyramidal tract fibers that arise not only from the motor cortex and caudal premotor cortex but also from the somatosensory and parietal cortices,allowing very early CT demonstration of wallerian degeneration of the pyramidal tract.
