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.

The authors report a case of ataxic hemiparesis (dysarthria-clumsy hand syndrome plus crural hemiparesis with homolateral ataxia), secondary to a single cerebellar lacuna (CT scan), in a left rostral para-vermian position in the vicinity of the peduncle and secondary to arterial hypertension. They discuss the nosological aspects of this recently established entity and the origin of particularly severe and persistent dysphagia in their case (cerebellar dysphagia?)

A 58-year-old female suffered frequent attacks of unconsciousness due to vertebrobasilar insufficiency. She had a slight left hemiparesis, dysarthria, gait disturbance, and decreased vibration sense. Angiography revealed remarkable stenoses of the bilateral vertebral artery origin with inadequate collateral flow from the anterior circulation. Percutaneous transluminal angioplasty (PTA) was performed on the more severely narrowed left vertebral artery through transfemoral approach. This was followed by PTA on the right one through transbrachial approach after an interval of 3 weeks. The procedure cleared off the signs and symptoms; neuroradiological studies including angiography and Xe-CT scan confirmed the improvement. PTA has been performed on stenotic lesions at the origin of the vertebral artery and the common carotid artery with more safety than on stenotic lesions of the other cerebral arteries, because of the smooth luminal non-ulcerated lesions of the former. In spite of the possibility of restenosis after PTA, in selected cases, PTA leads to good results, less complications and shorter stay in hospital. These factors are of major benefit to the patients. In the future, PTA may be an alternative method for treating arterial stenotic lesions in the field of neurosurgery.

Various types of associated movements of eyeballs with other cranial muscles have been described in the literature. Only a few observations, however, have been reported on the relation of ocular movements and facial muscles innervated by the facial nerve, especially the orbicularis oculi muscles. We report two cases presenting gaze-evoked involuntary contraction of the orbicularis oculi muscle and unilateral eyelid closure. Case 1 was a 38-year-old housewife who was admitted to our hospital because of gait disturbance and sensory deficits below the neck. She had a 5-year history of left facial palsy, disturbed horizontal eye movements, retrobulbar optic neuritis, spastic paraparesis and bladder and rectal disturbances, some of which had relapsed a few times. Neurological abnormalities were summarized as follows: bilateral pale discs, right Horner's sign, horizontal nystagmus, left facial nerve palsy of peripheral type, spastic paraparesis with left-sided predominance, sensory disturbances below the third cervical segment, truncal and limb ataxia, and bladder and rectal disturbances. Gaze-linked synchronized contraction of the left facial muscles was observed and on the left lateral gaze marked spasm of the left orbicularis oculi muscle with occasional lid closure was evoked. Case 2 was a 72-year-old female with cerebellar hemorrhage. Neurological abnormal findings included mild disorientation, meningeal irritation signs, horizontal nystagmus on lateral gaze, reduced response of reflex eye movement to the left, minimal weakness of the left facial muscles, ataxic dysarthria, mild left hemiparesis and hemisensory deficits with face, truncal and limb ataxia. She could move eyeballs to any direction but with effort to the left.(ABSTRACT TRUNCATED AT 250 WORDS)

Distinct chronic posttraumatic syndromes, ascribed to neurological deficits of patients suffering severe head injuries and being in prolonged coma, are much less frequently encountered in the literature than acute traumatic syndromes. The major components of the posttraumatic midbrain syndrome, resulting from compressive necrosis or vascular infarction at the midbrain level, are ipsilateral cerebellar signs (the predominant one being intention tremor), contralateral pyramidal signs (the predominant one being a spastic-dystonic hemiparesis), dysarthria, and mild to moderate intellectual impairment. Significant bilateral cerebellar dysfunction following head injury, without pyramidal, extrapyramidal, or pseudobulbar signs, constitutes a posttraumatic cerebellar syndrome. Its most disabling component, namely posttraumatic intention tremor, may be alleviated by thalamotomy. Following severe closed head injury, an infrequently encountered posttraumatic entity of dystonic hemiplegia or hemiparesis, which may be alleviated by thalamotomy, can occur, but does not have a specific neuroanatomical basis. Intention tremors following severe head injuries, rarely associated with hydrocephalus and without other significant cerebellar findings, can develop as a dysfunction of the cerebellofugal outflow system. While chronic posttraumatic syndromes can be complex and difficult to treat, cerebellar stimulation has been utilized ipsilaterally to modulate limb spasticity, and bilateral ventrolateral cryothalamectomies staged 4-6 months apart have been successful in alleviating severe (intractable) intention tremors.

We reported a 71-year-old male with lateral medullary syndrome presented acute respiratory arrest after ataxic respiration. The patient had experienced transient diplopia repeatedly for about 2 weeks and then the developed persistent diplopia and vertigo. On the third day he was admitted to our hospital because of neurological deterioration and aspiration pneumonia. He showed left Horner's sign and double vision. And he had sensory disturbances of pain and temperature in the left face and the right side of the body, left limb ataxia and truncal ataxia. He showed dysarthria, severe dysphagia and left mild central facial paresis, but no hemiparesis. This case was clinically considered to be a typical case of left lateral medullary syndrome. When he was admitted to our hospital, he showed hypoxia with hypercapnea in spite of no history of chronic obstructive pulmonary disease. This condition was considered to be a central alveolar hypoventilation. He had two episodes of sudden-onset respiratory arrest following ataxic respiration on the 4th and 5th days, but no cardiac arrest. He was supported his respiration by mechanical ventilation until he was able to breathe spontaneously on the 29th day. The 22nd day MRI disclosed high intensity area in the left lateral and dorso-medial medulla in T2-weighted image, and this lesion was 1.5 cm in length. Therefore this case was diagnosed medullary infarction. This case developed ipsilateral facial pain in chronic stage. Pain existed around the eye and in the cheek, and pain was like toothache and unbearable like thalamic pain.(ABSTRACT TRUNCATED AT 250 WORDS)

The term lacuna or lacunar cavity defines the pathological lesion while the clinical pictures due to lacuna or lacunes are referred to as 'lacunar syndromes'. The lacunar syndromes include: (1) the typical lacunar syndromes or lacunar syndromes proper--pure motor hemiplegia, pure sensory stroke, ataxic hemiparesis including dysarthria and clumsy hand, sensorimotor stroke and abnormal movement syndromes, (2) reversible ischemic attacks (TIA and/or PTIA or RIND), (3) other clinical syndromes which may be due to lacunar lesions such as suprabulbar palsy; lacunar dementia, or subacute arteriosclerotic encephalopathy (or Binswanger's disease). The different clinical pictures are reviewed, some mechanisms underlying the lacunar lesion are briefly discussed and the old label 'small vessel diseases' in cases with lacunes is reconsidered.

Eighteen patients with subcortical lobar hematomas were reviewed. Arterial hypertension was the leading cause and three had arteriovenous malformation and were treated surgically. More than half of cases had hematomas of either the temporooccipital or occipital lobes. Common neurologic findings were headaches, vomiting, alertness, dysarthria, hemiparesis and hemianopsia. All patients survived and had better resolution of neurological deficits, suggesting that surgical intervention is not necessary.

A previously healthy 6-year-old boy, suddenly developed a complete right hemiparesis and dysarthria while playing at school without any history of trauma. All laboratory examinations were normal except for CT brain scan that revealed a small ischemic infarct in the left middle cerebral artery territory. Four vessel cerebral angiography demonstrated a left internal carotid artery dissective obstruction while filling of the right or left vertebral artery resulted in the simultaneous retrograde appearance of the respective middle cerebral artery possibly via the posterior communicating artery. In contrast to the literature data, the patient showed a significant recovery with conservative treatment. This uncommon stroke type in children and the possible protective role of the posterior communicating artery's collateral are further discussed.

A child affected by cardiomyopathy from the age of 12 months suddenly manifested right hemiparesis and dysarthria at the age of 48/12 years. Emergency brain CT showed a hemorrhage in progress in the left thalamic area. A severe form of hypertension was concomitant and resisted all pharmacological treatment. Retrograde transfemoral aortography pointed out an atrophy of the right renal artery. This finding, together with the high renin and aldosterone values, indicated a nephrogenic hypertension causing both the cardiomyopathy found at 12 months of age and the endocranial hemorrhage. Right nephrectomy led to normalization of blood pressure.
