A REVIEW of 31 cases with necropsy which presented a clinical picture of transverse or diffuse "myelitis" revealed the striking fact that in 9 the lesion of the cord was a myelomalacia secondary to malformation of the vessels of the spinal cord. These nine cases, in five of which the lesions were diffuse and in four focal, are considered in the present report.
Knowledge of such malformations is not new. The presence of vascular abnormalities has been noted by neurosurgeons in certain cases of spinal compression. Numerous reports of this association have appeared in the literature.1 Congenital malformations may also result in a myelitic picture of a special type, and this was first described by Foix and Alajouanine2 as myélite nécrotique subaigue.
The clinical characteristics given by these authors were of progressive paraplegia, at first spastic, then flaccid with atrophy, the process advancing slowly upward in the spinal
