Infantile progressive spinal muscular atrophy with ophthalmoplegia and pyramidal symptoms.
Two siblings presented with identical features of progressive peripheral paralysis of the lower motor neuron type, pyramidal signs, cranial nerve palsy which included external ocular palsy and deafness, and internal ocular palsy; both died before 1 year of age. Pathologic examination of the central nervous system in both patients revealed degeneration and loss of spinal and cranial nerve motor nuclei, including the oculomotor nucleus. In addition, there was degeneration of the Edinger-Westphal nuclei and demyelination of the corticospinal tract under the midbrain. Although spinal cord lesions were indistinguishable from those of Werdnig-Hoffmann disease, the 2 patients are not considered to have Werdnig-Hoffmann disease from the clinicopathologic findings.
