A 15-year-old boy suddenly developed a headache, followed by progressive weakness of the right extremities. A computed tomographic scan obtained on admission showed a low-density area in the left putamen extending to the internal capsule. No neurological deficits were observed other than slight dysarthria and right hemiparesis. Left carotid angiography showed the characteristic "string of beads" deformity of fibromuscular dysplasia (FMD) extracranially and complete occlusion of the internal carotid artery at the C2 portion. The right carotid artery and both vertebral arteries were normal. Anastomosis of the left superficial temporal and middle cerebral arteries was performed 1 month after the onset. The patient recovered quickly from the hemiplegia and was discharged with no neurological deficits. Angiograms obtained 3 months later showed not only patency of the bypass, but also recanalization of the intracranial internal carotid artery. Cervico-cephalic FMD mainly affects middle-aged women, and is uncommon in children; only nine childhood cases have been reported. This disorder may play an important role in the genesis of strokes among children.

Anterior corpus callosotomy was performed in a patient with pseudobulbar palsy, mild mental retardation and intractable epilepsy related to congenital bilateral perisylvian cortical dysplasia. Before surgery, she had daily atonic drop attacks, rare and mainly sleep-related oromotor seizures, and multifocal and diffuse paroxysmal EEG discharges; after callosotomy, less abrupt atonic drop attacks recurred monthly and the EEG epileptiform abnormalities disappeared. Video-EEG sleep recordings revealed the clinically unsuspected serial recurrence of oromotor seizures, probably related to the clinically observed aggravation of dysarthria. New surgical techniques, in addition or alternative to callosotomy, should be developed in order to avoid or reduce the risk of aggravating some types of partial seizures in patients with bilateral cortical displastic lesions, intractable epilepsy and epileptic falls.

Foix-Chavany-Marie Syndrome or anterior opercular syndrome constitutes the cortical form of pseudobulbar palsy. Its most common etiology is stroke in the region of either operculum. Clinically it can be characterized by severe dysarthria and facio-pharyngo-glosso-masticatory dysplasia with automatic-voluntary dissociation. An inversion of this classical dissociation can be seen in patients with emotional paralysis in the face, in whom asymmetry of emotional expression but conservation of voluntary movement can be seen. The lesional topography of this inverse dissociation corresponds to the supplementary motor area. both processes support the existence of an anatomical base which is different for emotional movements and voluntary types. We describe the clinical case of a 65 year old woman with a history of breast cancer who presented a subacute and progressive clinical picture of dysphagia and severe dysarthria. Upon neurological examination slight velo-palato-pharyngea was noticed; most relevant was paralysis of the facial muscles for either emotional or automatic movements while voluntary innervation was maintained. Neuroradiological studies show the presence of brain metastasis located in both Roland opercula. Although the neuroanatomic bases for automatic-voluntary dissociation remain unclear, our case lends weight to the evidence that impulses for voluntary and emotional movements originate in different cortical areas or else take a different route through the brain. We have been unable to find any cases of biopercular lesion with inverse dissociation described in the literature we reviewed.

Congenital bilateral perisylvian syndrome (CBPS) is a recently described, neuronal migration disorder, characterized by pseudobulbar palsy, epilepsy and mental retardation and bilateral perisylvian dysplasia. A 15-year-old boy was diagnosed with CBPS according to the typical clinical, and magnetic resonance imaging (MRI) features. The patient was suffering from atypical absence seizures, repeating daily in spite of antiepileptic drug therapy, since age 7 years. He had also experienced rare generalized tonic-clonic seizures and complex partial seizures. Neurological examination showed severe restriction of tongue movements, severe dysarthria, dysphagia, facial diplegia, mild pyramidal signs and moderate mental retardation. A computed tomographic (CT) scan demonstrated bilateral perisylvian enlargement. The diagnosis was corrected with MRI after six years. Frequent irregular generalized spike and wave abnormalities and focal sharp and slow waves over the posterior regions of both hemispheres were shown by electroencephalograms (EEG). The patient was treated with Na-Valproate, carbamazepine and lamotrigine but did now show any significant change in seizure frequency in the eight-year follow-up period. Intractable seizures, mental retardation and particularly congenital pseudobulbar palsy suggest this congenital entity. Those patients who exhibit these typically clinical features, must have MRI.

A 47-year-old man developed progressive muscular weakness in the left arm. MR images revealed low intensity signal lesions with ring enhancement by Gd-DTPA in right fronto-parietal lobes. At that time cerebral angiography was not performed because he refused. A tuberculin skin test showed strongly positive reaction and then administration of anti-tuberculous drugs was started. His symptom had remained stable for one year, but left facial palsy and dysarthria added about two years later. MR images revealed expansion of the lesions in right parietal lobe, adding cortical high intensity signal lesions with Gd-DTPA enhancement on T1-weighted images. Angiography disclosed tubular stenosis of right internal carotid artery at the portion of cervical to petrous segment and the local stenosis at right renal artery. These lesions were considered to be caused by fibromuscular dysplasia, but not atherosclerosis, because we could not find any atherosclerotic lesions in other arteries including right carotid bifurcation. His manifesting symptoms were ascribed to slowly progressive cerebral ischemia. And peculiar MRI findings in his early stage resembled those of inflammatory granulomatous diseases.

Around a quarter of Friedreich ataxia (FA) patients, despite being homozygous for GAA expansion within the FRDA gene, show atypical presentations. Our aim is to describe the case of three brothers with long-term follow-up suffering from late onset FA manifested with spastic ataxia. The three patients belong to a family with occipital dysplasia (OD) and Chiari I malformation previously reported by us. We have carried out serial examinations since 1977. Electrophysiological and neuroimaging studies, and molecular genetic analyses of hereditary ataxias are available in all three patients. Onset of symptoms occurred between 25 and 35 years. The clinical picture consisted of progressive spastic gait, truncal and limb ataxia, dysarthria, nystagmus, hyperreflexia with knee and ankle clonus and extensor plantar response, and mild hypopallesthesia. Ages at present vary between 50 and 59. One patient is wheelchair-bound but the other two are able to walk with support. Leaving OD aside, skeletal anomalies are not prominent. All three patients showed cardiomyopathy. MR imaging revealed atrophy of the cerebellum and spinal cord. Motor and sensory nerve conduction velocities were normal. Central conduction time of both motor and sensory pathways was delayed or unobtainable. All three patients were homozygous for the GAA expansion, the smaller expanded allele ranging between 131 and 156 repeats. Four heterozygotic carriers were detected among non-ataxic relatives including one with OD; furthermore, an asymptomatic OD patient showed normal genotype. We conclude that adult onset spastic ataxia is a distinctive FA phenotype associated with minimal GAA expansion. This phenotype represents a new cause of selective distal degeneration of central sensory axons. The present concurrence of OD and FA reflects coincidental cosegregation of two different inherited disorders.

Club foot is a common congenital deformity, for which a neurogenic process in utero has been proposed in some severe forms, but in most cases its cause remain uncertain. We report on four patients with an unilateral (three cases) or bilateral (one case) clubfoot and a bilateral perisylvian cortical dysplasia. All had severe dysarthria with mild mental retardation, epilepsy occurred in three cases. Direct evidence of fetal lesions of the spinal cord was occasionally present, such as signs of motor axonopathy in two cases analyzed by electrophysiological methods and syringomyelic cavitation at the thoracic level in one case. Even though the sensitivity of the investigations to demonstrate microcopic scars in the spinal cord remains weak, the presence of polymicrogyric rearrangements in the perisylvian cortex, known to proceed from a transient ischemic process occurring in the carotid territory during mid-gestation, strongly suggests that a similar mechanism occurred in the spinal cord. In fact, the foot deformity cannot be viewed as the consequence of lesions to brain regions that do not control the foot motility in the fetus. Extraneurological lesions such as jejunal atresia, possibly proceeding from localized vascular compromise, were also encountered. In one sibship, one sister was found to have a severe developmental anomaly of one foot, suggesting that genetic factors may be involved.

Congenital bilateral perisylvian syndrome (CBPS) is a rare neurological disorder characterised by pseudobulbar palsy, cognitive deficits and epilepsy associated with bilateral perisylvian cortical dysplasia on neuroimaging studies. We report a long-term follow-up of a 18-years girl diagnosed with CBPS according to the typical clinical and magnetic resonance imaging (MRI) features. The patient showed faciopharyngoglossomasticatory diplegia, severe dysarthria, ataxia, spastic quadriparesis and severe mental retardation. Brain MRI evidenced bilateral perisylvian cortical dysplasia. Since early life she suffered from complex febrile seizures and epilepsy consisting of complex partial attacks with affective manifestations associated with centro-temporal EEG abnormalities. During 18 years of follow-up she was treated with phenobarbital, carbamazepine, lamotrigine, gabapentin but did not show any significant clinical improvement. Subsequently, monotherapy with phenytoin (PHT) was followed by a significant clinical improvement. At age 17, because of adverse effects, PHT was gradually substituted by topiramate (TPM). Full control of seizures was obtained at the age of 17 years with TPM. EEG abnormalities throughout the years have been reduced according to the clinical course. These findings emphasised the importance of long-term follow-up, suggesting that the prognosis for epilepsy may not be predicted based on the early response to treatment or on the presence of structural encephalic abnormalities, as reported in the literature.

We have recently encountered a rare case of fibromuscular dysplasia (FMD) of the vertebral artery (VA) presenting as lateral medullary syndrome. A 39-year-old male was admitted to our hospital due to vertigo, dysarthria and numbness of the left face and the right limbs. A magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of brain revealed lateral medullary infarction in the territory of the left posterior inferior cerebellar artery (PICA). The angiography of the VA revealed tubular stenosis of the left extracranial VA and a focal vascular kinking as well as web in the right extracranial VA, confirming the diagnosis of FMD. We present this rare case to emphasize that FMD could be one of the risk factors causing lateral medullary syndrome in young people.

We report a 45-year-old woman with arrhythmogenic right ventricular dysplasia (ARVD). Because of congestive heart failure and atrial fibrillation, she underwent tricuspid valvular replacement and warfarin was prescribed. She suddenly had dysarthria, left hemiparesis and left hemispatial neglect. After brain CT examination, and cerebral angiography, she was diagnosed as cardiogenic brain embolism and infusion of low molecular heparin was started. On day 25, she suddenly had ventricular tachycardia and died in spite of treatment for arrhythmia. This is the first report of the case of cardiogenic brain embolism following ARVD. In this type of case, we must take care of arrhythmia besides the management of atrial fibrillation and brain infarction.
