A 69-year-old woman presented with a progressive limb weakness. Both clinical and neurophysiological findings were consistent with diagnosis of Guillain-Barré syndrome (GBS). Two days after admission, the patient suffered from an acute coronary syndrome without stenosis at coronary arteriography. Echocardiography revealed left ventricular inferior wall and apical akinesia and decreased ejection fraction. A diagnosis of Takotsubo cardiomyopathy was then made. Left ventricular dysfunction and electrocardiography normalized within one month. Takotsubo cardiomyopathy can be developed as a complication of GBS. (Korean J Clin Neurophysiol 2015;17:73-75)

Background: Cavernous sinus (CS) dural arteriovenous fistulas (DAVFs) are abnormal arteriovenous shunts involving the dura mater, located within or near the walls of the CS. Transvenous embolization is considered to be an effective treatment for CS DAVF. We describe a novel technique for the use of transvenous Onyx embolization in the treatment of CS DAVF, which uses a temporary balloon to occlude the arterial side for flow control. Case Report: A 63-year-old woman presented with ocular pain and ptosis of the left eye. Cerebral angiography showed a left CS DAVF fed by multiple branches of the left external carotid artery. We successfully treated the CS DAVF using transvenous Onyx embolization with temporary balloon occlusion of the proximal feeding artery to decrease the shunted flow. Conclusion: Transvenous Onyx embolization with flow control via temporary balloon occlusion may be a useful technique for the embolization of CS DAVFs with multiple arterial feeders.

The Wallenberg’s syndrome is produced by infarction of lateral medulla. Isolated ipsilateral axial lateropulsion withoutother common symptoms of Wallenberg syndrome has rarely been reported as manifestation of lateral medullaryinfarction. The responsible anatomical structure of ipsilateral axial lateropulsion is still uncertain. We describe a patientwith lateral medullary infarction who present with isolated ipsilateral axial lateropulsion without other symptoms ofWallenberg syndrome.

Oculomotor nerve palsy is underrecognized clinical manifestation of extracranial internal carotid artery (ICA) dissection. Herein we report a case of complete oculomotor nerve palsy following endovascular revascularization, which developed in a patient with acute stroke due to extracranial ICA dissecting occlusion. We also discuss about the development mechanism of oculomotor nerve palsy, considering the vascular anatomy and the possibility of periprocedural complications during endovascular treatment.

Cerebral intraventricular hemorrhage (IVH) is an extremely rare complication of carotid artery stenting (CAS). Fully dilated terminal arteries of a chronic, severely stenosed proximal artery could be ruptured by impaired autoregulation of cerebral blood flow. Hyperperfusion syndrome can occur even if there is no blood pressure fluctuation during the CAS. We report a case of an isolated IVH that occurred hours after CAS.

Mitochondrial encephalomyopathy with lactic acid and stroke-like episodes (MELAS) is a multisystem mitochondrial disorder that is rarely observed in adulthood. We report a case of MELAS syndrome diagnosed in a 22-year-old man presented with status epilepticus (SE) without a preceding stroke-like episode. Genetic testing revealed a mutation of heteroplasmic m.3243A>G. MELAS should be suspected in patients with recurrent, uncontrolled SE with unexplained severe lactic acidosis.

Diffusion-weighted imaging (DWI) hyperintensities corresponding to ischemic areas have been regarded as an ischemic core. However, several studies have demonstrated the reversibility of DWI hyperintense signals in hyperacute stroke patients. We experienced the DWI reversibility of posterior circulation ischemia after revascularization of the proximal extracranial vertebral artery. The perfusion of the posterior circulation might be significantly reduced due to bilateral vertebral art ery occlusion. Considering this case, early improvement of the perfusion of the ischemic area might key role of DWI reversibility.
