Internuclear ophthalmoplegia has been infrequently described in patients with systemic lupus erythematosus. We report a 23-year-old woman with lupus who presented with bilateral internuclear ophthalmoplegia and skew deviation. Additional neurologic findings included dysarthria, hemifacial weakness, hemiparesis, and dysmetria. Computed tomography of the patient's brainstem was unremarkable while magnetic resonance scanning demonstrated two areas of infarction. Magnetic resonance imaging is superior to computed tomography in both neuroradiographic study of the brainstem as well as evaluation of patients with neurologic complications of lupus.

Lacunar strokes result from occlusion of penetrating arteries in the deeper, subcortical parts of the cerebrum and brain stem. Approximately 19 percent of all strokes are of the lacunar variety with lacunar strokes representing the most common cerebrovascular complication of chronic hypertension. Four major clinical syndromes are pure motor hemiparesis, pure sensory stroke, ataxic hemiparesis, and the dysarthria-clumsy hand syndrome. The advent of computed tomography (CT) has allowed the antemortem study of lacunar disease and has shed new light on the pathogenesis and clinical course of lacunar strokes. Recently, it has been demonstrated that lacunar strokes may be embolic or hemorrhagic in causation, are not invariably associated with hypertension, and may be larger and associated with hypertension, and may be larger and associated with neurological manifestations that do not conform to the classic patterns. In most instances, however, recognition of the characteristic clinical presentation and confirmation of the diagnosis with noninvasive studies spare many patients unnecessary risks associated with anticoagulation, arteriography, or vascular surgery.

Dolichoectatic intracranial arteries (DIA) have been given several names, e.g. fusiform aneurysms, dolichomega-arteries. It is not an uncommon condition and it raises interesting points: 1) symptoms and signs result from compression (cranial nerve palsies; hydrocephalus) from ischemic or hemorrhagic episodes; 2) the diagnosis is made easier with CT since the arterial wall is often calcified; 3) the pathophysiology has long been assumed to be atherosclerotic in nature, but controversial assumptions are discussed; 4) associated arterial abnormalities are common: one of our cases and approximately half of the post mortem reported DIA were associated with aneurysm of the abdominal aorta. Two cases are reported here: 1) A 56 y/o male presented with progressive gait disorder, deafness and ischemic episodes. CT showed DIA and hydrocephalus. DIA involved the basilar artery, both intracranial carotid arteries, the abdominal aorta and probably one renal artery. A ventriculo-atrial shunt was performed unsuccessfully. Post mortem findings are reported; 2) A 52 y/o male had suffered from trigeminal neuralgia for about one year and from trigeminal permanent pain for two weeks. He had developed left hemiparesis and dysarthria. DIA involved the basilar artery and the left intracranial internal carotid artery. The right internal carotid artery and the right vertebral artery were hypoplastic. Clinical, radiographical and pathophysiological features are reviewed.

A 31-year-old woman was admitted because of severe headache and dysarthria in December 1985. Neurological examination on admission revealed severe impairment of consciousness, anisocoria, absent light reflex on the right side, and evidence of left hemiparesis, but other brainstem reflexes were intact. A CT scan taken shortly after arrival demonstrated a large hematoma in the right temporal lobe and the right cerebellum. Breathing became irregular and intubation was needed. An emergency operation was performed. After the operation the patient remained comatose without any spontaneous respiration or brainstem reflexes. The next day she was still comatose without any spontaneous movement and other neurological finding remained unchanged. An initial EEG obtained at this time showed an 8- to 9-Hz alpha rhythm of about 15-40 microV with preponderance over the posterior and central regions. Some spontaneous variability was noted. The same day, investigations of brainstem auditory evoked potential (BAEP), visual evoked potential (VEP), and somatosensory evoked potential (SEP) were performed. BAEP showed only the first, second and third waves (I-III) bilaterally. VEP was able to elicit the primary response (II-III) without the secondary response. SEP could not be obtained from the early cortical response to left median nerve stimulation, but showed N14 bilaterally and small N20 upon right median nerve stimulation. On the second day of hospitalization, a repeated EEG showed generalized slowing with loss of alpha frequency rhythms and it proved impossible for SEP to elicit N20 bilaterally. At this time, BAEP showed bilateral I-IIIth waves and VEP still showed primary response.(ABSTRACT TRUNCATED AT 250 WORDS)

We examined case of intracerebral hemorrhage presenting as lacunar syndrome. Of 115 cases, 10 presented with a lacunar syndrome: 3 presented with pure motor hemiparesis, 1, pure sensory stroke, 1, ataxic hemiparesis, 5, sensorimotor stroke, and, none, dysarthria--clumsy hand syndrome. The sites of hemorrhage were capsular in 1, pontine in 1, thalamic in 4, and putaminal in 4. In these 10 patients, 9 were hypertensive, and the signs characteristics of parenchymal hemorrhage, e.g., headache, nausea, vomiting, and stiffness of neck, were absent or rare.

Aneurysm of the vein of Galen is a very rare disease. The authors present a case of secondary aneurysm of the vein of Galen which was confirmed by characteristic clinical symptoms, brain CT and angiographic findings. The patient was a 14-year-old right handed girl with intermittent headache, nausea, vomiting, dysphasia and gait disturbance. Neurologic examination revealed dysarthria, nasal voice, blurring of both margins of optic discs, truncal ataxia and dysdiadochokinesia. Sensory function was normal but right hemiparesis was seen. Roentgenogram of the skull revealed diffuse thinning of the calvarium, widening of sella turcica and erosion of clinoid processes. Computed tomogram of the brain showed dilatation of all ventricles and round hyperdense mass behind the third ventricle in the midline. The lesion was enhanced markedly and homogeneously. Left and right internal carotid angiograms showed arteriovenousmal-formation with drainage to the aneurysm of the vein of Galen.

Although spontaneous thrombosis of a giant intracranial aneurysm is comparatively common, its parent artery occlusion is rare. Recently we experienced two cases in which spontaneous thrombosis of giant intracranial internal carotid artery aneurysm and occlusion of its parent artery were occurred. Case 1. A 49-year-old man, complaining esotropia was referred to us by an ophthalmologist. He had no particular past history. Neurological examination revealed left oculomotor, abducens palsy and disturbance of left trigeminal first branch. CT scan revealed a round high density mass in the left middle fossa. The size was 3 cm in diameter. Left CAG revealed severe stenosis of left internal carotid artery and in delayed phase, faint shadow was seen near posterior clinoid process. MRI revealed a high intensity mass of the intraaneurysmal thrombus in the left middle fossa with small low intensity area indicating residual lumen. With conservative treatment, the symptom was gradually improved and one month after admission, complete occlusion of the left internal carotid artery was seen by angiography. The patient returned to his previous occupation. Case 2. A 21-year-old man was admitted to our hospital complaining dysarthria and left hemiparesis. He had been diagnosed as left internal carotid giant aneurysm 5 years before when he had suffered from right visual disturbance. Neurological examination revealed left hemiparesis and dysarthria. CT scan revealed high density mass which extended from the base of the right middle fossa to the third ventricle.(ABSTRACT TRUNCATED AT 250 WORDS)

A rare case of persistent primitive first cervical intersegmental artery (proatlantal artery II) is reported. A 58-year-old man was admitted to our hospital with dysarthria and left hemiparesis. On admission he was stuporous with bilateral gaze palsy and left hemiparesis. CT scan on admission showed low density areas in the right cerebellar hemisphere and ventricular part of the pons. Right retrograde brachiography revealed occlusion of the basilar artery, aplasia of the right vertebral artery and an abnormal vessel connecting the right external carotid artery and the right vertebral artery. This anastomotic vessel was thought to be a persistent primitive first cervical intersegmental artery (Proatlantal artery II). Left carotid angiography revealed the left posterior cerebral artery was visualized through the posterior communicating artery, leading from the internal carotid artery. Left retrograde brachial angiography showed that the left vertebral artery terminated just distal from the branching of the left posterior inferior cerebellar artery. After admission the left hemiparesis deteriorated gradually and tracheotomy was done due to respiratory difficulties. The patient was then transferred to the rehabilitation center on his 34th day in hospital with neurological deficits.

A case of multiple spontaneous intracerebral hematomas is presented. A 67-year-old man with 7 years history of hypertension had sudden clumsiness in his right hand and an hour later dysarthria appeared. A CT scan taken 3 hours after the onset revealed two well demarcated high density areas in the left putamen and in the parietal subcortex. A diagnosis of multiple intracerebral hematomas was made. On neurological examination he was midly stuporous (13 points of Glasgow Coma Scale). Dysarthria, right hemiparesis and right extensor plantar response were seen. CT scan of 6 hours later disclosed the same findings as the previous study. He recovered well and neurologically free in a few days. On the following CT scans both hematomas were isodense 2 weeks later, and ring-like enhancement effect was noted. CT scan showed normal appearance 7 weeks later. On MRI using 0.5 T unit t-1 and t-2 weighted spin echo images of these hematomas also showed the similar chronological changes. The history, these CT and MRI studies suggest that two hematomas of this case occurred almost simultaneously in one cerebral hemisphere. No causative factors such as blood dyscrasias, AVM, angioma, septicemia, malignancies or sinus thrombosis was identified. We consider that a hypertensive intracerebral hematoma of the putamen was followed by the parietal intracerebral hematoma within a few hours, although amyloid angiopathy was not completely excluded because no cerebral biopsy of the lesion was performed.

A prospective long-term semiquantitative evaluation of the results of ventral intermediate-posterior ventral oral nucleus thalamotomy on the different aspects of dystonia was made in 29 patients with secondary disease, 12 with nonfamilial, eight with (non-Jewish) familial, and seven with atypical DMD. The effect of disease progression, even in secondary patients, on surgical outcome was reviewed. Thalamotomy resulted in a long-term improvement in limb function of more than 25% to 50% in 23% of the patients, over 50% in 34% of patients, but midline features responded poorly. Manual dexterity was little changed in secondary cases because of underlying paralysis but improved 38% in cases of DMD. Involvement of neck and trunk, of three to four limbs, and progressive disease prognosticated for a poorer result, but phasic and tonic, familial, and nonfamilial dystonia respond equally well and age at surgery made no difference. Significant complications in 29 secondary cases included one death 31 days postoperative, one case of worsened hemiparesis, two cases of worsened dysarthria, two cases of worsened locomotion, one case of hydrocephalus requiring shunting, and one case of need for permanent tracheotomy. In 27 cases of typical and atypical DMD, there were two instances of hemiparesis, two of significant speech deterioration, three of hand ataxia, one of postoperative seizures, and one of hydrocephalus requiring shunting for an overall significant morbidity rate of 21%. The limiting factor in treating secondary dystonia is the underlying spastic paralysis but that in DMD is the relentless postoperative progression. The overall results of this study are remarkably similar to those of other published series: a quarter of the patients improved by 25% to 50%, a quarter to a third by more than 50%. The analysis of effect on specific features of the disease may be useful in the future for predicting outcome in a particular patient.
