title: [Medial medullary infarct].
abstract: Medial medullary infarct is a rare type of brain stem infarction first described in 1908. It was only since the broad use of MRI that an accurate clinical topographical correlation could be documented in survivors. We observed two patients; one of them had an anteromedial unilateral infarction in the upper medulla, and the clinical picture was characterized by contralateral hemiparesis, facial weakness, dysarthria and palatal weakness. The outcome was good. The second patient however showed a severe tetraparesis with only minor brain stem signs, secondary to bilateral anteromedian infarction with a large craniocaudal extension. He survived with severe residual impairment. The most likely cause of infarction was arteriosclerosis of the A. vertebralis and A. spinalis anterior, respectively. These two different cases suggest that the medial medullary syndrome is heterogeneous comprising small unilateral infarctions with mild clinical signs as well as large bilateral infarctions with a poor outcome.
