Neurofibromatosis type 1 with basilar artery fusiform aneurysm manifesting Wallenberg's syndrome.
A case of neurofibromatosis type 1 (NF1) manifesting Wallenberg's syndrome and fusiform aneurysm of the basilar artery is reported. The patient suddenly developed dysarthria, walking difficulty and sensory disturbance. Neurological examination suggested Wallenberg's syndrome and MR imaging confirmed an ischemic lesion at the left lateral medulla oblongata. Cerebral angiography revealed a fusiform aneurysm at the middle portion of the basilar artery. However, there was no occlusive change in either the posterior inferior cerebellar artery or the vertebral artery. The clinical and radiological features are discussed together with a review of NF1 cases with intracranial aneurysms in the literature.
