A 9-year-old boy presented with a 12-month history of headaches and recent grand mal seizures. Computed tomography and magnetic resonance imaging of the brain revealed an enhancing right frontal convexity lesion. The preoperative diagnosis was meningioma. However, histological examination was diagnostic of Rosai-Dorfman disease. Rosai-Dorfman disease… (More)
This case report describes a patient with sciatica resulting from lumbar root compression by a gas-containing cyst in the extradural space. Removal of the cyst provided prompt relief. The origin and anatomic distribution of gas collections in the spine are considered based on a review of the literature.
PURPOSE This study evaluated factors affecting reading performance in a sample (N = 544) of older adults (mean age 72.8 years, range 58 to 102) with good high-contrast acuity (> or = 20/32). METHODS Using the Pepper Reading Test, the relationship between reading rate and several vision measures was assessed. RESULTS Mean corrected reading rate fell… (More)
A group of 48 patients, consecutive apart from exclusions, from a 1-year series of 60 cases of aneurysmal subarachnoid haemorrhage (SAH), was reviewed, in respect of clinical and radiological features, surgical management, clinical outcome, psychological distress and psychometric status, the neuropsychological assessment being compared with a… (More)
The association between findings on the neurologic examination and the clinical diagnosis of Alzheimer's disease was investigated among 467 individuals from a geographically defined community population. Participants were selected by stratified random sampling based on their memory performance in a population survey of community residents 65 years of age… (More)
The purpose of the present study was to define the late effects, both physical and psychological, of treating low-grade astrocytomas with radiotherapy. Fifty patients, half of whom received radiotherapy, underwent an assessment of neurological and neuropsychological function. There was no difference in neurological function between the two groups. The… (More)
A girl aged 13 years presented with spontaneous intracerebral haemorrhage. Initially, no cause could be found but she was later found to have a low grade pilocytic astrocytoma. This very uncommon presentation was not considered before surgery.
The position of an intracerebral haematoma shown on computerised tomography (CT) of patients who have suffered a recent spontaneous subarachnoid haemorrhage is a powerful indicator of the source of the bleed. In the absence of such a parenchymal clot, does the distribution of intraventricular blood have similar predictive value? The scans of 22 patients… (More)
AIMS Fluoroscopic-guided right ventricular (RV) endomyocardial biopsy (EMBx) is the conventional method for obtaining myocardial samples to assess for rejection following heart transplantation. This study was designed to assess the feasibility and accuracy of guiding RV sheath and bioptome tip position using real-time three-dimensional echocardiography… (More)
A rare case of metastasis to the spinal subarachnoid space from a non-neuraxial primary tumor is presented. Dissemination was shown by computerized tomography to be via the cerebrospinal fluid from secondary deposits in the central nervous system and meninges. This route would seem to be the most common mode of spread to the spinal subarachnoid space.
