our speculated mechanism of ipsilateral cerebral hemiatrophy due to thalamic tumor is that thalamic tumor causes the degeneration and disappearance of thalamic ganglion cells and nerve fibers , consequently occurring secondary waller 's degeneration of afferent and projecting fibers from the thalamus as well as retrograde degeneration of efferent fibers , thus resulting in an extensive atrophy of the cerebral cortex and subcortical tissue .
