1/2680. 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.

2/2680. 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. ( info)

3/2680. 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.

4/2680. 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.

5/2680. Massive haemorrhage into acoustic neurinoma related to rapid growth of the tumour.

    Massive haemorrhage into a acoustic neurinoma is very rare. A large size, mixed Antoni type and secondary vascular changes are thought to be causative factors. We describe a patient with a rapidly growing acoustic neurinoma which led to a massive haemorrhage. Rapid growth of the tumour seems to be another risk factor for haemorrhage. ( info)

6/2680. Pure apraxic agraphia with abnormal writing stroke sequences: report of a Japanese patient with a left superior parietal haemorrhage.

    A 67 year old Japanese male patient had pure agraphia after a haemorrhage in the left superior parietal lobule. He developed difficulty in letter formation but showed no linguistic errors, consistent with the criteria of apraxic agraphia. He manifested a selective disorder of sequencing writing strokes, although he was able to orally state the correct sequences. The patient's complete recovery after 1 month, without new learning, showed that he had manifested a selective disorder of writing stroke sequences. These findings indicate that the final stage of the execution of writing according to acquired sequential memory shown as a stroke sequence can be selectively disturbed, and should be considered to be distinct from the ability of character imagery and the knowledge of the writing stroke sequence itself. This case also indicates that the left superior parietal lobule plays an important part in the execution of writing. ( info)

7/2680. 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. ( info)

8/2680. A case of amnestic syndrome caused by a subcortical haematoma in the right occipital lobe.

    A case of an amnestic syndrome caused by a subcortical haematoma in the right occipital lobe is reported. A 62-year-old right-handed man presented with a sudden onset of headache to the hospital. On admission, he had a left homonymous hemianopsia, disorientation and recent memory disturbance, but had normal remote memory and digit span. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a subcortical haematoma in the right occipital lobe. These findings suggest that the patient's amnesia was caused by a lesion of the retrosplenial region in the non-dominant hemisphere. ( info)

9/2680. Intracranial meningioma with hemorrhage.

    Intracranial meningioma with hemorrhage is not frequently reported. The available articles in the literature regarding intracranial meningioma with hemorrhage are reviewed to the best of our knowledge, and the sixty-one cases have so far been reported. The authors report three cases. In about half of the 64 cases including ours, the tumor was located at the convexity, and histologically classified as meningotheliomatous meningioma. The site of hemorrhage was mainly in the subarachnoid space. In most cases the onset of presenting signs and symptoms was acute. The mean age at the time of tumor hemorrhage was 51 years. There was no sex difference statistically. The importance of the diagnosis of associated hemorrhage and subsequent surgical intervention is emphasized. ( info)

10/2680. Cerebral bleeding, infarcts, and presumed extrapontine myelinolysis in hypernatraemic dehydration.

    The neuroimaging findings in an infant with hypernatremic dehydration are presented. brain parenchymal haemorrhage and extensive multiple infarcts were present in the acute stage. Follow-up CT showed bilateral, symmetrical changes presumed to indicate extrapontine myelinolysis in the thalamus and globus pallidus. MRI confirmed sparing of the pons. Only three previous cases of neuroimaging abnormalities due to hypernatraemia have been described in the radiological literature. ( info)
