title: [Oculomotor nerve nucleus syndrome: report of two clinical cases (author's transl)].
abstract: Two clinical cases are reported of similar oculomotor disorders presenting as a paralysis of the oculomotor nerve (III) on one side and isolated paralysis of the superior rectus on the other side. Previous reports of this clinical picture have not been found. Recent experimental studies have established that all the superior rectus motoneurons decussate and pass through the opposite II nucleus before entering the radicular portion. Therefore it is suggested that the reported syndrome results from an unilateral lesion in the III nucleus.
