✓ Computerized tomography (CT) has replaced pneumoencephalography and ventriculography in the diagnosis of intraventricular cysticercosis. The authors present a refinement in the use of CT by introducing a positive contrast medium into the ventricles to increase the definition of plain and contrast-enhanced scans in the diagnosis of intraventricular cysticercosis. Eleven cases of Cysticercus cyst are presented, 10 of which were precisely delineated by CT-iodoventriculography. In the remaining case, lack of definition was due to obstruction of the cerebral aqueduct. Surgical confirmation was obtained in all cases.

✓ Jefferson fractures in children are exceedingly rare. A case in a 2-year-old is reported, and the other only case in the literature is reprinted. The mechanism of fracture is probably separation of the lateral masses by a force transmitted from the vertex. Because these fractures are not usually associated with neurological deficits, and because of the poor detail obtained with conventional radiography in a child, these fractures may be overlooked. Computerized tomography provides superb definition of this lesion. The preferred mode of treatment is immobilization.

✓ Two patients with benign intracerebral cysts are reported and a brief review of the literature is given. Although computerized tomography (CT) scanning is useful in detecting a variety of intracerebral cysts, the CT findings are not specific for any lesion. An exploratory operation with establishment of an adequate route of drainage and a histological examination of the cyst wall are mandatory in the management of patients with a progressive but benign lesion.

Object. Despite a long and controversial history, psychosurgery has persisted as a modern treatment option for some severe, medically intractable psychiatric disorders. The goal of this study was to review the current state of psychosurgery. Methods. In this review, the definition of psychosurgery, patient selection criteria, and anatomical and physiological rationales for cingulotomy, subcaudate tractotomy, anterior capsulotomy, and limbic leukotomy are discussed. The historical developments, modern procedures, and results of these four contemporary psychosurgical procedures are also reviewed. Examples of recent advances in neuroscience indicating a future role for neurosurgical intervention for psychiatric disease are also mentioned. Conclusions. A thorough understanding of contemporary psychosurgery will help neurosurgeons and other physicians face the ethical, social, and technical challenges that are sure to lie ahead as modern science continues to unlock the secrets of the mind and brain.

✓ The production model of the Brown-Roberts-Wells (BRW) computerized tomography (CT) stereotaxic guidance system is described. Hardware and software modifications to the original prototype now allow the system to be used independently of the CT scanner after an initial scan with the localizing components fixed to the skull. The system is simple and efficient, can be used universally with all CT scanners, and includes a phantom simulator system for target verification. Preliminary experience with 74 patients at two institutions is described. It is concluded that CT stereotaxic guidance systems will become important tools in the neurosurgical armamentarium, as they allow accurate approach to any target identifiable on the CT scan.

✓ In a consecutive series of 39 cases of acute subdural hematoma (SDH), encountered since computerized tomography diagnosis became available, 61.5% were found to be the result of bleeding from a small cortical artery, 25.6% were of venous origin, 7.7% resulted from cerebral contusions, and 5% were acute bleeds into chronic subdural hematomas. Craniotomy was performed promptly on admission, but there was no difference in survival (overall 51.3%) between patients with arterial and venous bleeds. The only apparent factor affecting survival in this series was the preoperative neurological status: 67% of patients who were decerebrate and had fixed pupils prior to operation died. Of patients with less severe neurological dysfunction, only 20% failed to survive.

Age Related Changes

Object. The purpose of this study was to establish a standard curve to demonstrate normal age-related changes in the proportion of intracranial cerebrospinal fluid (CSF) space in intracranial volume (ICV) during each decade of life. Methods. Using volumetric computerized tomography (CT) scanning and computer-guided volume measurement software, ICV and cerebral parenchymal volume (CPV) for each decade of life were measured and the intracranial CSF ratio was calculated by the following formula: percentage of CSF = (ICV − CPV)/ICV × 100%. The standard curve for age-related changes in normal percentages of intracranial CSF was obtained. Conclusions. Based on this standard curve, the percentage of intracranial CSF rapidly increased after the sixth decade, seeming to reflect the brain atrophy that accompanies increased age.
