The case histories of 125 children with hypertension and no apparent primary CNS disease were analyzed for neurological symptoms or complications. Eleven children had neurological symptoms of high blood pressure. In only one of these patients was the diagnosis of arterial hypertension made before the observation of the neurological findings. The symptoms were severe headache in eight children, convulsions and coma in four, hemiplegia in two, and impaired vision and apraxia in one child. Symptomatology was rapidly reversed by antihypertensive treatment in four children, while six had long-term stigmata and one child died in hypertensive crisis. Because elevated arterial pressure can cause severe neurological disease, routine blood pressure measurement in children--especially those with neurological symptomatology--is stressed.

Frontal agraphia has always been a subject of interest, although very few documented case reports have been published. A 57 year old male clerk, suffering from adenocarcinoma of the signoid colon, presented with mild headache and difficulty in writing. Minor features of dysphasia could be detected, but there were no alexia, agnosia or apraxia. Brain scan and angiography confirmed a metastasis in the posterior part of the left prefrontal region. The patient was able to write single letters, and had no difficulty with automatic writing or copying. The writing of words and of sentences was more affected. After a brief review of the literature and discussion, the authors concluded that frontal agraphia is related to frontal lobe diorders, especially the inability to translate verbal signals into motor behaviour (i.e. writing).

Higher cerebral dysfunctions such as aphasia, apraxia and agnosia have seldom been reported in multiple sclerosis (MS). 12 year-old right-handed boy felt unsteadiness of the body and headache for several days. Two months later, he had the same episode and complained of visual disturbance, and weakness and sensory disturbance on the face and the extremities. Additionally, he showed amnestic aphasia, acalculia, ideomotor apraxia, finger agnosia and right-left disorientation. Cerebrospinal fluid examinations revealed increases IgG, myelin basic protein and neuron specific enolase (11%, 25 ng/ml and 28.8 ng/ml, respectively). X-ray CT scan and MRI-CT examinations revealed sclerotic lesions on the left parietal white matter and the right mid-brain. The diagnosis was made as MS. He was treated with m-PSL (methyl-prednisolone) pulse therapy for three weeks and consecutively treated with PSL for four weeks. He recovered gradually, but visual disturbance and facial palsy remained. After seven months MRI-CT showed a high signal intensity on the left parietal white matter in spite of the disappearance of the lesion on X-ray CT scan. We suggest that these higher cerebral dysfunctions may result from the lesion of the left parietal white matter which produces a disconnection between each cortical area.

Reported is the case of a patient who underwent surgical resection of a brain metastasis from a hepatocellular carcinoma. The 62-year-old male was admitted to hospital because of headaches and a left hemiparesis. Six years earlier he had undergone transcatheter arterial embolization for a hepatocellular carcinoma. Further, one year ago the lower lobe of his right lung had been resected because of a pulmonary metastasis from the same tumor. A neurological examination on admission revealed disorientation, dressing apraxia, and a left hemiparesis. A CT scan revealed two highly dense masses with peripheral low dense areas in the right temporoparietal region, which were heterogenously enhanced with a contrast medium. Right carotid angiogram showed tumor stains in the same region. Also, a magnetic resonance T1 weighted image showed highly intense masses, and a T2 weighted image showed low intensity masses with prominent brain edema. Thus, a right fronto-temporo-parietal craniotomy was performed, and the two masses were removed. Histological examination revealed hepatocellular carcinoma. The postoperative course was uneventful, and the left hemiparesis improved gradually, enabling the patient to walk without assistance. A brain metastasis from a hepatocellular carcinoma has been rarely reported in the literature since the survival period is very short due to rapid disease progression at the primary site, so that most reports have been based on postmortem examination. The MRI, CT, and the angiographic findings are included in this report.

A 12-year-old boy with corticosteroid-responsive mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) is described. His mother proved to have an asymptomatic mitochondrial myopathy on examination of a muscle biopsy specimen. Three weeks after the onset of vomiting, headache, ataxia and visual and speech impairment, he presented with a background of somatic growth retardation, deafness and school failure. Examination revealed disorientation, dysphasia, dyspraxia, optic atrophy, hemianopia, hemiparesis and sensory inattention. A cranial computed tomographic scan disclosed a large, low-density area, which was consistent with infarction, in the left posterior hemisphere and marked calcification of the basal ganglia bilaterally. Within two weeks of the commencement of corticosteroid treatment, the neurological dysfunction resolved. Attempts to decrease the dosage of dexamethasone caused an exacerbation of symptoms repeatedly. Two weeks after ceasing corticosteroid therapy, the patient developed a serious neurological relapse and a new, large, low-density area, which resembled an infarction, in the right posterior hemisphere on a computed tomographic scan. The reintroduction of corticosteroid therapy again resulted in the rapid resolution of all symptoms. It became evident that the patient had an exquisitely sensitive corticosteroid dependency, whereby a reduction in the dexamethasone dosage of even 0.25 mg a day caused confusion, headaches and increasing lactic acidaemia. Although it is difficult to assess the impact of various therapies in MELAS because of the episodic natural course of the disease, this remarkable corticosteroid responsiveness also has been noted in four previously reported patients with MELAS syndrome; therefore, it would seem reasonable to suggest that corticosteroid therapy now should be considered as standard treatment for this condition. However, corticosteroid therapy in other forms of mitochondrial disorders still awaits careful evaluation.

A case of multiple cerebral hemorrhage in the bilateral parietal lobes related to cerebral amyloid angiopathy (CAA) is reported. A 66-year-old man was admitted to our hospital because of headache and vomiting on Feb. 21, 1983. He had no history of hypertension, diabetes mellitus, recent head injury, or dementia. Four days prior to admission, he had behaved as if he were blind, but, had denied any blindness. On examination, he was confused and disoriented. Blood pressure was 130/80 mmHg. Abnormal findings on neurological examination included memory disturbance, apraxia for dressing, right-left disorientation, finger agnosia and Balint's syndrome. A CT scan showed multiple subcortical hematomas in the bilateral parietal lobes. Intracerebral hemorrhage related to CAA was suspected. Confirmation of the presence of amyloid in the cerebral vessels was established by examination of brain biopsy specimens. The characteristics of cerebral hemorrhage related to CAA are as follow--occurrence in elderly, sometimes demented people; localization to the cortex and subcortical white matter, with direct extension into the subarachnoid space; frequent multiple occurrence in time and/or at several sites within the cerebral hemispheres; sometimes occurrence after operative procedures or head injuries. A specific diagnosis of CAA can only be made by histological examination, but the indication of brain biopsy should be carefully decided because of hemostatic difficulty and tendency to rebleed. In conclusion, CAA should be considered as a cause of hemorrhage in elderly patients who are often normotensive and demented.

An autopsy case of subacute encephalopathy with disseminated necrosis was reported. The patient, a 34-year-old male, complained of headache and generalized convulsion. He also showed constructional apraxia and dementia. These symptoms progressed slowly. Neurological examinations revealed no abnormalities except for a slight optic nerve atrophy. Laboratory examinations disclosed a high ratio of the titer of antibody of rubella virus. Based on the findings mentioned above, he was diagnosed as atypical subacute encephalopathy, and because of his usage of thinner for 10 years, intoxication by it was also suspected. An autopsy of the brain revealed disseminated small necrosis in the gray matter over the whole brain. The relationship between the genesis which provoked the atypical clinical course and pathological findings was discussed.

A case of astrocytoma whose first clinical presentation was diagnostic dyspraxia was reported. A 38-year-old right-handed male experienced funny motion of his left hand triggered by voluntary movement of his right hand. One day, he tried to insert a coin into the vending machine with his right hand, then the left hand was against the other. One month after that event, he experienced headache and vertigo. On admission, there were no abnormal findings on neurological examination. On neuropsychological examination, he was cooperative, well orientated and attentive, and there were no callosal disconnection symptoms. Frontal lobe function tests were slightly impaired. T1-weighted MRI demonstrated irregular mixed signal intensity mass lesion extending from the genu to the body of the corpus callosum and the cingulate gyrus. This lesion was slightly enhanced with Gd-DTPA. Biopsy was performed and histological diagnosis was fibrillary astrocytoma. After irradiation and chemotherapy, he was discharged from the hospital without evident neurological deficit. About 20 cases of diagnostic dyspraxia have been reported and almost all of them were caused by cerebro-vascular disease. This is the first case of brain tumor who presented diagnostic dyspraxia.

Three patients with large or huge meningiomas of the pineal region presented with headache, vomiting, gait and visual disturbance, apraxia, agnosia, and transient amnestic aphasia. Computed tomographic scans revealed round, high-density areas of 8 x 7 x 7 cm, 5 x 5 x 4 cm, and 3 x 3 x 3 cm in the pineal region. Angiography revealed that the bilateral internal cerebral veins and the great vein of Galen were stretched and significantly displaced upward in one patient, and downwards in the other two. The meningiomas appeared to originate from the verum interpositum and falcotentorial junction, respectively. The tumors were removed subtotally or totally via an occipital interhemispheric transtentorial approach and/or infratentorial supracerebellar approach. The postoperative courses were uneventful, and no neurological deficit was detected postoperatively. Pineal region tumors with a maximum diameter of 5 cm or larger should be operated on via a unilateral or bilateral occipital interhemispheric transtentorial approach, regardless of the angiographic findings, because this permits a wide operative field and can be followed, if necessary, by an infratentorial supracerebellar approach. Selection of the operative approach for a relatively small pineal region tumor should depend on the angiographic findings: downward displacement of the bilateral internal cerebral veins and the great vein of Galen indicates an occipital interhemispheric transtentorial approach, whereas upward displacement indicates an infratentorial supracerebellar approach.

A case of ruptured distal anterior cerebral artery aneurysm presenting with diagnostic dyspraxia is presented. A 54-year-old female was referred to our hospital with the complaint of sudden onset of headache followed by disturbance of consciousness. CT and MRI revealed subarachnoid hemorrhage with hematomas in the interhemispheric fissure and the supracallosal area, and CAG revealed a left-sided callosomarginal artery aneurysm. During and after hospitalization, she showed diagnostic dyspraxia characterized by behavior of both her hands opposite to what might be expected e.g. when she tried to pick up a bowl, both her hands moved forward and held it at once; she wiped her head and face with toilet paper after urination. At times her hands behaved in opposite ways. For example, while folding cloths, her right hand tended to fold them while the left hand tended to unfold them; when she put on a sweater, as the right hand put it on, the left hand took it off; when she put her shirt into her trousers, one hand pushed it in while the other hand pulled it out. This unusual behavior was considered to be caused by the impairment of the corpus callosum due to compression by the hematoma. It disappeared gradually over a period of one year. Involuntary motor behavior of the left hand while the right hand is in voluntary action is known as diagnostic dyspraxia. Although this symptom has rarely been reported so far in cases of ruptured distal anterior cerebral artery, it may become noticed more frequently through careful observation.
