Isolated one-and-a-half syndrome with pontine cavernous angioma: successful surgical removal.

Author information

Department of Neurology, University of Pennsylvania School of Medicine, Philadelphia.


We report a patient with a pathologically proven pontine cavernous angioma and a horizontal one and a half syndrome. Following recurrent hemorrhages, the vascular malformation was removed from the dorsal pons using microsurgical techniques with partial resolution of the motility disturbance. This case demonstrates that vascular malformations of the brainstem parenchyma may be removed, thereby precluding further hemorrhage and facilitating the return of neurologic function.
