The volume of the encephalic ventricles was determined from computerized tomographic (CT) and magnetic resonance imaging (MRI) scans of seven subjects without apparent pathology and three subjects with enlarged ventricles. Since there are many conditions in which the encephalic ventricles become enlarged such as Alzheimer's disease and hydrocephalus,(More)
Four patients with clinical criteria of cerebral death were evaluated by computerized cranial tomography (CT). Upon intravenous infusion of meglumine diatrizoate, the intracranial vascular structures failed to enhance. Two of the patients also had electroencephalographic evaluation, and one patient underwent cerebral angiography, confirming the absence of(More)
Two cases of traumatic pseudoaneurysm and arteriovenous fistula involving the middle meningeal artery are reported with a review of the world literature on these specific entities. The two conditions appear to evolve through similar mechanisms and may lead to a confusing clinical picture. High quality angiography is important in making an early diagnosis,(More)
Intracranial hemorrhage developed in two patients with meningioma without other apparent risk factors predisposing to hemorrhage. Bleeding has been reported to be associated with meningiomas regardless of the sex or age of the patient or the location of histological nature of the tumor. It can occur acutely without antecedent symptoms, often masking the(More)
Computed tomography has been the procedure of choice in evaluation of cerebral hemiatrophy, particularly in those instances where plain radiographic studies of the skull are nondiagnostic. Our experience suggests that magnetic resonance (MR) can easily accomplish the same task. Furthermore, by virtue of its exquisite soft tissue detail, MR can afford(More)
BACKGROUND Myelopathy in Klippel-Trenaunay-Weber syndrome is uncommon but has been reported secondary to spinal vascular malformations. REPORT A patient with Klippel-Trenaunay-Weber syndrome who presented with spinal cord compression from a spinal extradural mass lesion (angiomyolipoma) is described. DISCUSSION This association has not been reported(More)
BACKGROUND Although maxillofacial injuries in the elderly population frequently result from falls and motor vehicle crashes, the association between osteoporosis and fractures of the maxillofacial region remains poorly defined. OBJECTIVE To evaluate the relationship between osteoporosis and maxillofacial trauma in the elderly. DESIGN, SETTING, AND MAIN(More)
A 27-year-old woman with a small cerebral arteriovenous malformation and a primitive trigeminal artery had subarachnoid hemorrhage. This case and a review of the literature suggest that some of the "spontaneous" subarachnoid hemorrhages reported in patients with a primitive trigeminal artery may have been due to rupture of an unrecognized small(More)
OBJECTIVE AND IMPORTANCE This is the first report of delayed cervical epidural hemorrhage caused by an onlay silastic graft placed over the dura after laminectomy. There are several reports of intracranial hemorrhage associated with silastic implants in the literature. CLINICAL PRESENTATION A 49-year-old woman suddenly developed severe neck pain and(More)
