1/1590. Intracranial hemorrhage due to cerebral metastasis of lung cancer - a case report.lung cancer often metastasizes to brain. However, hemorrhage of the metastatic lesions is uncommon. We report a case of a 68-year old man with lung cancer who underwent right upper lobectomy of the lung and presented in 15 months with a cerebral hemorrhage from a metastatic lesion of the brain.- - - - - - - - - - ranking = 1keywords = cerebral, brain (Clic here for more details about this article) |
2/1590. Intracerebral hemorrhage caused by cerebral amyloid angiopathy: a case report.cerebral amyloid angiopathy (CAA) accounts for approximately 10% of spontaneous intracerebral hemorrhages (ICH), and typically occurs in the cortex and subcortical white matter. It is characterized by the deposition of amyloid fibrils in the leptomeningeal, cortical and subcortical arteries. Pathologically, amyloid is stained pink with congo red and shows yellow-green birefringence when viewed under polarized light. Although there have been many reports of CAA in the literature, it has rarely been described in taiwan. This is the report of a case of a 75-year-old man with ICH caused by CAA. The postoperative course was uneventful. The incidence of this disease increases with age. The authors, therefore, suggest conducting a brain biopsy and special stain for CAA in each operative case of spontaneous ICH, especially in the elderly.- - - - - - - - - - ranking = 1.7844424327281keywords = cerebral, brain (Clic here for more details about this article) |
3/1590. Angiographical extravasation of contrast medium in hemorrhagic infarction. Case report.Leakage of the contrast medium was noted on angiograms of a patient whose autopsied brain disclosed typical pathological findings of hemorrhagic infarction. The case was a 63-year old woman with mitral valve failure, who suddenly had loss of consciousness and right-sided hemiplegia. The left carotid angiography performed six hours after onset demonstrated middle cerebral arterial axis occlusion, and the second angiography performed three days after onset displayed recanalization of the initially occluded artery as well as extravasation of the contrast medium. Fourteen days after onset the patient died and an autopsy was performed. The brain demonstrated perivascular punctate hemorrhages in the area supplied by the middle cerebral artery, and neither hematoma nor microaneurysm was disclosed pathologically. A short discussion is given on the possible relationship between recanalization and hemorrhagic infarction. The clinical assessment of hemorrhagic infarction has not been established successfully.- - - - - - - - - - ranking = 0.40718041566396keywords = cerebral, brain (Clic here for more details about this article) |
4/1590. Multiple postoperative intracerebral haematomas remote from the site of craniotomy.A postoperative haemorrhage is a common and serious complication of a neurosurgical procedure. It usually occurs at the site of the surgery, but on occasion a postoperative haematoma is found at a distance from the previous craniotomy. Multiple postoperative haemorrhages are extremely rare. We report the case of a 63-year-old woman, operated on for the removal of a supratentorial astrocytoma, who developed in the early post-operative period multiple bilateral intracerebral haematomas without involvement of the surgical bed.- - - - - - - - - - ranking = 0.98803264056007keywords = cerebral (Clic here for more details about this article) |
5/1590. Fatal haemorrhagic infarct in an infant with homocystinuria.Thrombotic and thromboembolic complications are the main causes of morbidity and mortality in patients with homocystinuria. However, it is unusual for thrombosis and infarction to be the presenting feature leading to investigation for homocystinuria and cerebrovascular lesions in the first year of life. We describe a previously healthy 6-month-old infant who presented with a large middle-cerebral-artery territory infarction and died of massive brain swelling. homocystinuria due to cystathionine beta-synthase (CBS) deficiency was diagnosed by metabolite analysis and confirmed by enzymatic activity measurement in a postmortem liver biopsy. homocystinuria should be considered in the differential diagnosis of venous or arterial thrombosis, regardless of age, even in the absence of other common features of the disease. We recommend systematic metabolic screening for hyperhomocysteinemia in any child presenting with vascular lesions or premature thromboembolism.- - - - - - - - - - ranking = 0.25036714647246keywords = cerebral, brain swelling, brain, swelling (Clic here for more details about this article) |
6/1590. Abrupt exacerbation of acute subdural hematoma mimicking benign acute epidural hematoma on computed tomography--case report.A 75-year-old male was hit by a car, when riding a bicycle. The diagnosis of acute epidural hematoma was made based on computed tomography (CT) findings of lentiform hematoma in the left temporal region. On admission he had only moderate occipitalgia and amnesia of the accident, so conservative therapy was administered. Thirty-three hours later, he suddenly developed severe headache, vomiting, and anisocoria just after a positional change. CT revealed typical acute subdural hematoma (ASDH), which was confirmed by emergent decompressive craniectomy. He was vegetative postoperatively and died of pneumonia one month later. Emergent surgical exploration is recommended for this type of ASDH even if the symptoms are mild due to aged atrophic brain.- - - - - - - - - - ranking = 0.0059836797199628keywords = brain (Clic here for more details about this article) |

8/1590. Acute hemorrhagic leukoencephalitis in patients with acute myeloid leukemia in hematologic complete remission.The authors describe the cases of three patients affected by acute myeloid leukemia, in complete remission, who rapidly developed neurologic symptoms leading to death. Neither clinical characteristics, nor radiological or microbiological procedures, allowed an etiological diagnosis of the neurologic syndrome. Post-mortem examination of the brain showed both macroscopic and microscopic findings compatible with acute hemorrhagic leukoencephalitis. The difficulty in distinguishing this entity from other CNS disease-related complications (e.g. leukemia infiltration, drug toxicity, hemorrhages) should not lead to an underestimation of the true incidence of this complication. We believe that with more attention to the possibility of this complication there would probably be both a greater possibility of collecting clinical informations about the real impact of this dramatic disease and a stronger hope of finding the right treatment for it.- - - - - - - - - - ranking = 0.0059836797199628keywords = brain (Clic here for more details about this article) |
9/1590. Intraventricular hemorrhage as a false localizing sign of a thoracolumbar arteriovenous malformation: case report.BACKGROUND: Spinal arteriovenous malformation (SAVM) is a relatively rare disease characterized by a high incidence of intramedullary and subarachnoid haemorrhage. When the hemorrhage is profuse and the SAVM is in the cervical region the symptoms (disturbance of consciousness, papilledema, cranial nerve palsies, and convulsions) may be so severe and rapid in their onset that they may be mistaken for intracranial hemorrhage. We report here on a patient with a SAVM at T10-12, which bled intracranially, mainly intraventricularly, and resulted first in respiratory arrest and unconsciousness. CASE DESCRIPTION: The patient had been well until he was 28 years old when, during intercourse, he suffered a terrible headache and suddenly lost consciousness, with a transient respiratory arrest. He was also noted to have right hemiparesis. A computed tomography scan demonstrated intraventricular hemorrhage. After a 24-hour period of artificial ventilation the patient regained consciousness and the right arm paresis completely recovered, but a gradual worsening of the motor function of the left leg developed. Digital subtraction angiography did not demonstrate any intracranial source of bleeding, whereas spinal angiography revealed a SAVM located at the medullary cone, which was totally removed by surgery. CONCLUSION: The case reported here raises several important issues. First, the advisability of spinal magnetic resonance imaging in the investigation of intraventricular (and subarachnoid) hemorrhage in patients with no demonstrable intracranial source. Secondly, the benefits of early diagnosis and reestablishment of the spinal cord circulation before the onset of thrombosis and the progressive phase of myelopathy. Finally, the necessity of complete obliteration and treatment of SAVMs even in patients with fixed neurologic deficits, because rebleeding of lower thoracic or lumbar SAVMs can lead to impairment at a higher level with severe or lethal consequences.- - - - - - - - - - ranking = 0.00061927602718949keywords = edema (Clic here for more details about this article) |
10/1590. Unidirectional dyslexia in a polyglot.Alexia is usually seen after ischaemic insults to the dominant parietal lobe. A patient is described with a particular alexia to reading Hebrew (right to left), whereas no alexia was noted when reading in English. This deficit evolved after a hypertensive right occipitoparietal intracerebral haemorrhage, and resolved gradually over the ensuing year as the haematoma was resorbed. The deficit suggests the existence of a separate, language associated, neuronal network within the right hemisphere important to different language reading modes.- - - - - - - - - - ranking = 0.19760652811201keywords = cerebral (Clic here for more details about this article) |
