The case report is presented of a 24-year-old male who developed the clinical signs and syptoms of pseudotumour cerebri (intracranial hypertension) twice during the course of protracted rejection 1 and 4 months after renal transplantation. Clinically, headache, nausea, hypertensive crisis and, finally, severe coma with an acute mid-brain syndrome was observed. Neurologically a mild left-sided hemiparesis was found on the second occasion. Examination of the fundi revealed bilateral papilloedema. Electroencephalograms showed pathological changes of a diffuse nature, later followed by abnormal delta range activity in the right frontotemporal projection. The withdrawal of corticosteroid therapy may have been responsible for the pseudotumour cerebri in this case.

Arterial hypertension causes the formation of small lacunes, or ischemic brain infarcts, which may result in transient ischemic attacks, hemiparesis, sensory loss, ataxic hemiparesis, or dysarthria. Usually these effects are reversible with physical therapy, but multiple lesions may lead to dementia. Prevention of lacunar disease is possible with vigorous control of hypertension.

Seven cases of SLE with concomitant neurological syndromes are reported. In 2 cases brain stroke with right-sided hemiplegia and aphasia developed, in the remaining cases brain-stem stroke with subarachnoid haemorrhage, progressive hemiparesis and signs of intracranial hypertension, chorea, status epilepticus in terminal uraemia were observed. In one case myasthenia coexisted. Severe neurological syndromes were preceded by signs of involvement of other organs and in most cases by low-grade signs of central nervous system involvement. Treatment with corticosteroids and immunosuppressants resulted in significant improvement without complete remission. A retrospective survey of clinical material showed that modern therapeutic methods have improved the prognosis in systemic lupus erythematosus independently of central nervous system involvement.

A 45-year-old man suddenly developed right hemiparesis and aphasia during work and lost conciousness next day, when he was admitted to us. Lumbar puncture showed bloody C.S.F. with the initial pressure of 220 mm H2O. Physical examination revealed hypertension and arteriosclerosis. Cerebral angiogram revealed an arteriovenous malformation in the left frontoparietal-parasagittal region and a saccular aneurysm at the left internal carotid-posterior communicating artery junction. In addition, the existence of putaminal hematoma was suspected on account of the displacement of the left anterior cerebral artery and the left lenticulostriate arteries. On the fourth day after admission his consciousness returned and the right hemiparesis gradually improved. One month later the disappearance of the displacement of the anterior cerebral artery was demonstrated by cerebral angiogram. A frontoparietal craniotomy was done and no hematoma was found around the arteriovenous malformation and the basis of the aneurysm did not adhere to the temporal lobe. Taking these findings into consideration, it is presumed that the hematoma in putaminal region was due to neither arteriovenous malformation nor aneurysm but was a hypertensive intracerebral hemorrhage.

A very rare case of a myxosarcoma with metastases to the brain is reported. A 33-year-old female was admitted to our hospital because of lassitude, fever, slight left hemiparesis, headache and other signs of intracranial hypertension and cardiac symptoms such as dyspnea and palpitation. She had the cardiac symptoms once 14 years before, which reappeared and rapidly aggravated two months before the admission. Cerebral angiography revealed a mass in the right temporal lobe and physical and laboratory examinations revealed mitral value failure and hyperthyroidism. On the next day, March 19, 1976, a grossly cystic 60 gm tumor was totally removed which was largely imbedded in the subcortex of the right temporal lobe. The symptoms except for the cardiac symptoms and disseminated intravascular coagulopathy rapidly improved, but headache and left hemiparesis returned 13 days postoperatively. She died suddenly 18 days after the operation due to acute cardiac failure. Autopsy revealed two separate hard and solid tumors both attached to the mitral valve and occupied the whole left atrium and another metastasis to the frontal lobe which had not been diagnosed before the death. Microscopic examinations including electronmicroscopic study established the diagnosis of myxosarcoma in all the four tumors.

Among 337 male patients who were hospitalized because of chronic ischemia of the leg, 103 (=30.6%) were shown to suffer from concomitant occlusive vascular disease of supraaortic branches. This was evaluated by simple examination like auscultation, bilateral blood pressure measurements, and palpation of pulses. In 52% the patients history revealed dizziness, hemiparesis and transient ischemic attacks (TIA). Arteriell hypertension promotes supraaortic vascular diseases as is shown by a relative frequency of 0.52 in contrast to 0.39. Combined occlusions of the iliac and femoropopliteal arteries are accompanied by supraaortic vascular disease in 40%, in femoropopliteal occlusion alone in only 20%. If the basic diagnostic approach is improved by directional ultra-sonic examinations of the carotid arteries, approximately 20% of all patients with advanced vascular disease of the iliac and femoropopliteal arteries have to be operated on for cerebrovascular disease.

Neuropathologic findings in 2 cases of cerebral lymphomatoid granulomatosis with sequelae are presented. A 30-year old male with macular rash and pulmonary lymphomatoid granulomatosis responded to Prednisone terapy but developed acute intracranial hypertension with coma. A necrotizing hemorrhagic lesion was evident in the left putamen surrounded by diffuse and perivascular atypical lymphoplasmacytic infiltration. An 18-year old girl developed pulmonary lymphomatoid granulomatosis, diplopia, slurred speech and right hemiparesis. Brain scan, angiography and EEG suggested a left fronto-parietal mass assumed to represent lymphomatoid granulomatosis. She responded well to cerebral irradiation, intrathecal methotrexate and cytoxan but relapsed with seizures and increasing respiratory insufficiency. At autopsy, stigmata of cerebral lymphomatoid granulomatosis were absent but a parenchymatous degeneration consistent with disseminated necrotizing leukoencephalopathy following antileukemic therapy in children, was found.

Two cases of delayed radiation necrosis of the brain were reported. Case 1 was a 50-year-old man who had right hemiparesis and disorientation 26 months after Linac irradiation (5,000 rad), preceded by the operation for right maxillar carcinoma. A left carotid angiogram demonstrated a left temporal mass lesion, extending the frontal lobe. Case 2 was a 41-year-old man who had previously the operation for right intraorbital plasmocytoma, followed by two times Co irradiation (6,400 rad, and 5,000 rad). He had the signs and symptoms of intracranial hypertension 36 months after last irradiation. A left carotid angiogram demonstrated a left temporal mass lesion. Both cases were treated by administration of steroid hormone, which alleviated the signs and symptoms, followed by the temporal lobectomy. Microscopic examinations showed necrosis of the brain tissues associated with hyaline degeneration of blood vessel walls and perivascular cell infiltration. The signs and symptoms of intracranial hypertension subsided postoperatively. The other thirteen cases as same as ours were collected from literature, which showed the signs and symptoms simulating a brain tumor (like a metastic brain tumor) after the irradiation to extracranial malignant tumors, and the diagnosis of radiation necrosis were made by the operation or autopsy. A follow-up for a long time is necessary, because the pathological changes in the brain may be progressive and extending in some cases, although the decompressive operations for mass lesion are excellent in result.

A case of central nervous system actinomycosis is reported. A 33-year-old male complained of headache, vomiting and blurred vision lasting for eight days prior to admission. On examination, a right hemiparesis, as well an intracranial hypertension were detected. The cerebrospinal fluid showed mild lymphomononuclear hypercytosis. Necropsy disclosed three abscess in the cerebral hemispheres, in addition to moderate cerebral edema on the left side but without purulent leptomeningitis. Actinomyces filaments and granules were demonstrated in the cerebral and lung abscessess. The Brazilian literature on actinomycosis is reviewed and six published cases with nervous system involvement were found. Relevant clinical and anatomical aspects of the cases and of the present one are discussed.

The authors report a boy aged 9 years in whom a giant meningioma of the small wing of the sphenoidal bone was removed surgically. Attention is called to the rarity of these tumours in the first decade of life. Developmental retardation, speech beginning at the age of 4 years, large head and epileptic seizures developing at the age of 7 years without signs of intracranial hypertension suggested the possibility of organic brain disease and development of massive hemiparesis, speech disturbances and choked disc in the last period of the disease were the cause of referral of the child to a neurosurgical unit. Plain skull films and angiography demonstrated changes typical of raised intracranial pressure and presence of an expanding lesion in the left cerebral hemisphere. Meningioma was found on operation hidden within the left frontal and temporal lobes but connected by means of a narrow band to the dura of the small wing of the sphenoidal bone. A good result was obtained. Follow-up examination after 2 years demonstrated slight neurological abnormalities and a very good general state of the child.
