The authors present the clinical and pathological features of a malignant triton tumour (MTT) in the lateral ventricle with neurofibromatosis type 1. A 57 year-old man presented with disorientation and memory disturbance. A Computed tomographic scan and magnetic resonance imaging studies revealed an enhancing lesion in the left lateral ventricle. A(More)
MRI was performed on 120 patients who sustained closed head injury of varying severity. Patients ranged in age from 4 to 87 years (average, 32 years). All patients had an initial MRI within 28 days (median 12 days) of injury. MRI disclosed areas of abnormal signals in the corpus callosum of 21 (18%) of the 120 patients; 1 (2%) of the 44 patients who(More)
A rare case of multiple traumatic aneurysms, arising from the distal anterior cerebral artery (ACA), associated with a diffuse axonal injury is presented. An 18-year-old male sustained a frontal impact injury in a traffic accident on February 19, 1988. He immediately lost consciousness and was transported to a local hospital where his Glasgow Coma Scale(More)
Two rare cases of entirely suprasellar Rathke's cleft cyst were reported. Case 1. A 62-year-old man was admitted to our hospital on the 14th of January, 1988, complaining of headache and diplopia. A plain skull x-ray showed the sella turcica was normal. CT scan and MRI demonstrated a lesion mass located entirely in the suprasellar cistern. Right(More)
OBJECTIVE Using auditory and visual stimuli including facial affective stimuli, we analyzed the P300 components of event-related potentials (ERPs) in patients after traumatic brain injury (TBI) to assess their cognitive characteristics. DESIGN Twenty TBI patients and 32 age-matched control subjects were recruited. Using conventional oddball paradigms,(More)
The importance of coexisting diffuse axonal injury (DAI) and outcome were studied in 107 patients with diffuse and focal brain injury. Comprehensive neuropathological study was undertaken in 26 fatal patients. There was a clear rank order of the mortality rate in the lesion type. The rank order of good recovery and moderate disability was also similar to(More)
Five unusual cases with massive haematoma of the corpus callosum caused by blunt head trauma are presented. Aside from the callosal haematomas, intraventricular and subarachnoid haemorrhages or small haemorrhagic foci in the basal ganglia or thalamus were common concomitant lesions on the computerized tomographic (CT) scan. The sites of the impacts were the(More)
Intracranial haemodynamics were studied in 20 patients with diffuse and focal brain injury and experimental animals with acute intracranial hypertension by the use of TCD ultrasound. The mean flow velocity in the middle cerebral artery (MCA) commonly decreased on the side of the haematoma depending on intracranial pressure (ICP) elevation and cerebral(More)
Among primary lacrimal gland tumors, adenoid cystic carcinoma (ACC) is the most common malignant epithelial neoplasm; it is characterized by local intracranial invasion. A case with unusual dumbbell-type intracranial extension representing cavernous sinus syndrome is described. A 49-year-old woman was admitted to our hospital with right cavernous sinus(More)
To the best of our knowledge, this is the first reported case of combined intracranial and extracranial hemorrhage due to aspergillus cerebral arteritis. Knowledge of the imaging and the importance of early diagnosis and treatment are emphasized. A 78 year old man developed progressive right-sided visual impairment and diplopia. Magnetic resonance imaging(More)
