title: MR-imaging of post-traumatic olivary hypertrophy.
abstract: We present clinical and magnetic resonance (MR) findings in 83 patients with inner cerebral trauma (ICT). In addition to the ICT-related lesions, uni- or bilateral enlargement and signal abnormalities of the inferior olivary nucleus were detected by MR in 9.6% of patients as a consequence of lesions within the dentato-rubro-olivary pathway. Clinically, segmental myoclonias were present in five patients. These observations suggest that MR imaging is highly sensitive in the detection of olivary hypertrophy and of causative traumatic lesions of the dentato-rubro-olivary pathway.
