the mechanism proposed for ipsilateral cerebral hemiatrophy due to thalamic tumor is that thalamic tumor causes degeneration and disappearance of thalamic ganglion cells and nerve fibers , with consequent secondary wallerian degeneration of afferent and projecting fibers from the thalamus as well as retrograde degeneration of efferent fibers , thus resulting in extensive atrophy of the cerebral cortex and subcortical tissue .
