We reported here a 64-year-old man with a central apnea resulted from unilateral medullary infarction. He was admitted because of cerebellar ataxia, dysarthria and dysphasia of abrupt onset. After the injection of diazepam for alcohol forbidden syndrome, he induced complete apnea and required the endotracheal intubation. At the spontaneous respiration under room air, his arterial blood gas showed hypercapnea without hypoxemia, and he fell into severe hypoventilation when hypnotic drug was injected. Respisomnogram revealed the frequent presence of central apnea both while he was awake and asleep. MRI demonstrated an abnormal high intensity area on T2 weighted image at the right lateral medulla just below the ponto-medullary junction. At autopsy, areas of the infarction were limited within the right lateral medulla, including lateral portion of the medullary reticular formation, the ambigual nucleus, one part of the solitary nuclear complex, the inferior cerebellar peduncle and the spinal trigeminal nucleus. However, the dorsomotor nucleus of vagus was completely free from the infarct lesion. There was no other lesion within central nervous system. Such a distribution seemed the minimal extent of the lesion responsible for central, apnea compared to the previous reports. We suggest that central apnea occurs not infrequently in the cases of 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.

A 30-year-old, right-handed female presented 2 weeks postpartum with acute-onset severe headache, vertigo, and vomiting. Initial neurologic examination illustrated lingual dysarthria, horizontal nystagmus, right dysmetria on finger-to-nose testing, and weakness of the extremities. Magnetic resonance imaging showed a large, left lateral medullary infarction (Wallenberg syndrome) with cephalad extension into the ipsilateral pons as well as involvement of the left middle cerebellar peduncle. The patient was discharged 3 weeks later to an inpatient rehabilitation facility with gradual improvement of her symptoms.

A 65-year-old man with a history of Wallenberg syndrome caused by vertebral artery dissection at 62 years old was admitted to our hospital with nausea, vertigo, right facial dysesthesia, right hemiplegia, crossed sensory disturbance (sensory loss and numbness in the right face and left body below the neck), and right limb ataxia. Magnetic resonance imaging (MRI) performed 80 minutes after onset revealed no acute ischemic stroke lesions, but magnetic resonance angiography (MRA) demonstrated complete occlusion of the right vertebral artery. Based on these neurological and MRA findings, atypical lateral medullary infarction was suggested, and intravenous tissue plasminogen activator (IV-tPA) was started 178 minutes after onset. Right hemiplegia improved immediately after IV-tPA administration. MRI performed on hospital day 2 showed an acute ischemic lesion on the right side of the medulla oblongata, resulting in a diagnosis of Opalski syndrome. Opalski syndrome is a rare subtype of Wallenberg syndrome accompanied by hemiplegia of the side ipsilateral to the lesion, and expansion of the stroke lesion to the corticospinal tract below the pyramidal decussation is considered to cause ipsilateral hemiplegia. Based on this case and previous reports, Opalski syndrome should be considered when limb ataxia and crossed sensory deficit are observed among patients with hyperacute-onset hemiplegia, and IV t-PA therapy should be considered even in the absence of neurological findings such as dysphagia, dysarthria, and Horner's signs and radiological evidence of acute ischemic stroke.
