A 77-year-old female presented with a rare aneurysmal subarachnoid hemorrhage accompanied by a remote hypertensive intracerebral hemorrhage. With a past history of hypertension, she suddenly developed right hemiparesis followed by delayed loss of consciousness. Left carotid angiography demonstrated a left internal carotid-posterior communicating artery aneurysm. The intracerebral hematoma was located in the posterior limb of the internal capsule ipsilateral to the ruptured aneurysm. The aneurysm was clipped with a fenestrated clip 3 weeks after the onset. The rise in blood pressure at the onset of intracerebral hemorrhage probably caused the rupture of the internal carotid-posterior communicating artery aneurysm.

A 20 year old woman was admitted to our Department 15 days after the onset of typhoid fever treated with chloramphenicol. The patient showed intracranial hypertension with generalized seizures, slight right hemiparesis and a left VI cranial nerve deficit with diplopia. Magnetic Resonance Imaging (MRI) showed occlusion of the superior longitudinal, right transverse, right sigmoid sinus combined with a single hemorrhagic infarct in the left occipito-parietal area. Serum tests were positive for Salmonella Paratyphi A and B. The results of cerebrospinal fluid (CSF) examination were normal and blood cultures were negative. Clinical data, laboratory and MRI examinations indicate that the neurological signs are the result of aseptic cerebral sinus thrombosis; the physiopathologic mechanisms of the case are discussed.

A 53-year-old man with hypertension was admitted to our hospital, for somnolence, horizontal gaze palsy, right hemiparesis and right sensory disturbance. Brain CT scan revealed a high density area from the left lower pontine tegmentum to the left tegmentum of the lower midbrain. As he became alert, he reported visual hallucination. Two weeks after onset of stroke, he complained tactile hallucination on his right half body with sensory disturbance. After disappearance of the visual hallucination, the tactile hallucination had been persisted. This is the first report of peduncular hallucinosis with long-persisted tactile hallucination due to brainstem bleeding. Tactile hallucination was suggested to be associated with sensory disturbance and extensive destruction of the brain stem tegmentum.

We reported a rare case of marked dilatation of the bilateral common carotid artery (CCA) associated with stenosis of the left middle cerebral artery (MCA). A 64-year-old female was admitted with right hemiparesis and dysarthria. She was hospitalized 2 years ago for cholecystitis. For 5 years, she has been under medical treatment for hypertension, diabetes mellitus, hyperlipidemia, cardiac failure associated with hypertrophic cardiomyopathy, and atrial fibrillation. Brain CT scan showed infarction of the left corona radiata. Angiography revealed marked dilatation of the bilateral CCA and the internal carotid artery (ICA), moderate dilatation of the innominate artery and the right subclavian artery, kinking of the right CCA, diverticular outpouching of the left ICA, and stenosis of the right external carotid artery and the left MCA. Breast CT scan revealed moderate dilatation and marked calcification of the ascending aorta and the aortic arch. Laboratory examination did not show any sign of inflammation, rheumatoid factor (RA), antistreptolysis-O (ASLO) and antinucleotic antibody. Based on the clinical course, radiological findings and laboratory data, possible diagnosis of the dilatation of the bilateral CCA was discussed with particular emphasis on arteriosclerotic aneurysm and aortitis syndrome.

Polyarteritis nodosa (PN) is frequently cause of both central and peripheral neurological disorders. However, involvement of the central nervous system is rare at the beginning of the disease. In this paper we report a case of a 38-year-old woman hospitalized in our Neurosurgical Service because of left hemiparesis in presence of cutaneous arteritis (PN). At computed tomography (CT) an intracerebral hemorrhage was found. No radiographic evidences of vasculitis of the visible arterial branches, at angiography, were seen. Cerebral arteritis should be suspected as a cause for intracranial hemorrhage in patients without hypertension or other risk factors.

We report a 47 year old woman that presented to the hospital with an intracranial hypertension syndrome, a right hemiparesis and a several months history of progressive malaise and behavioral disturbances. During the hospital stay, positive HIV antibodies were detected and CAT scan showed a profound left parietal rounded hypodense lesion. The patient died 21 days after admission and the postmortem pathological study showed a deep abscess in the left basal ganglia, with recognizable Toxoplasma gondii trophozoites.

Left pure motor hemiparesis occurred in a 42-year-old woman with a history of hypertension and diabetes mellitus. The left hemiparesis affected the arm and leg equally. The face was almost spared, with only a very slight facial asymmetry. Brain CT and MRI showed a small infarction located in the external 2/3 of the right cerebral peduncle. Cerebral angiography did not reveal significant abnormalities.

A 61-year-old woman was admitted to the hospital on September 18, 1991 because of left hemiparesis, dysphagia, and dysarthria since five days before. She was formerly pointed out diabetes mellitus and hypertension, but she did not receive any treatment. The MRI showed a high signal area in the right paramedian portion of the upper pons on T2 weighted image and proton image. The angiography showed that persistent primitive proatlantal artery originated from the left internal carotid artery and joined to the horizontal portion of the left vertebral artery. The image of carotid-vertebrobasilar system and proatlantal artery showed so severely arteriosclerotic. This is the first report of brainstem infarction with persistent primitive proatlantal artery. In this case, the pontine infarction was thought to occur on the basis of the arteriosclerosis of blood vessels and change of blood flow of carotid-vertebrobasilar system due to persistent primitive proatlantal artery.

A 50-year-old man with a history of hypertension developed right hemiparesis in February, 1985. Four years later, he noted tremor and involuntary extension of the neck (retrocollis) which was aggravated by walking or emotional stimuli. In addition to retrocollis, which was most pronounced upon turning the head to the left or backward, there also was upward deviation of the eyes (oculogyric crisis) and contraction of the left orbicularis oculi muscle. Magnetic resonance imaging study revealed one small old hematoma in the left posterior putamen and two in the right lenticular nucleus (one in the posterior putamen and the other in the globus pallidus). The findings in this case and in other reported cases of symptomatic retrocollis suggest that bilateral lesions of the putamen are associated with this type of focal dystonia.

Coarctation of the aorta (CoA) in adults is often accompanied by hypertension, but CoA combined with a cerebral arterial aneurysm is rare. We performed successfully descending thoracic aorto-aortic bypass grafting for CoA in an adult who had a cerebral bleeding and a cerebral arterial aneurysm. The patient was a 46-year-old female who had the history of hypertension. She suddenly suffered from left hemiparesis due to cerebral bleeding, then a left middle cerebral arterial aneurysm and CoA were detected at the same time. Aortography showed that the internal diameter of the portion of the coarctation was 2.8 mm and the poststenotic dilatation was prominent. The peak systolic pressure gradient across the coarctation was 60 mmHg. We took the precedence of the surgical repair for CoA over that for the cerebral arterial aneurysm, because her cerebral arterial aneurysm was judged to have less risk to rupture from the viewpoint of its size and shape by neurosurgeons. We performed proximal descending thoracic aorto-distal descending thoracic aortic bypass grafting with a woven double velour graft of 16 mm in internal diameter and 9.5 cm in length. Intraoperative cerebrovascular hypertension can be avoided by this procedure. Furthermore the peak systolic pressure gradient has disappeared immediately after grafting. In general, the coarctectomy with direct end-to-end anastomosis is prevalent for CoA in adults. On the other hand, the descending thoracic aorto-aortic bypass grafting for CoA in adults has rarely been reported.(ABSTRACT TRUNCATED AT 250 WORDS)
