title: [Posttraumatic intention tremor. Report of a case with a lesion in the mesencephalic area].
abstract: We present a child who suffered severe coma because of an automovile accident remaining two months in coma with brain stem dysfunction and one and a half additional months until he was able to recognize people. After recovering, he showed severe kinetic tremor in the upper right extremity and discrete right hemiparesis as well as a moderate clinical cerebellar disfunction. Magnetic resonance (MR) study, performed 1 and 3 years after the coma, showed normal images of the cerebellum and thalami, while it disclosed signal changes in the mesencephalic region next to both red nuclei, being more severe in the right side. It is suggested that the kinetic tremor can be related with location of the lesion near red nucleus.
