✓ Primary leptomeningeal gliomatosis is rare, and the diffuse form is even rarer with only three cases reported in the literature. A fourth case is described in this report. Computerized tomography (CT) findings showed hydrocephalus with enhancement of the cerebral cisterns, and analysis of cerebrospinal fluid obtained by lumbar puncture showed many atypical cells. Based on these findings, a diagnosis of leptomeningeal tumor was made. There was some improvement in neurological and CT findings following radiotherapy and chemotherapy.

✓ 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.

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.

Object. The goal of this study was fourfold: 1) to determine the incidence of traumatic subarachnoid hemorrhage (tSAH) in patients with traumatic brain injury (TBI); 2) to verify agreement in the diagnosis of tSAH in a multicenter study; 3) to assess the incidence of tSAH on the outcome of the patient; and 4) to establish whether tSAH itself leads to an unfavorable outcome or whether it is a sign of major brain trauma associated with severe posttraumatic lesions. Methods. Computerized tomography (CT) scans obtained in 169 head-injured patients on admission to 12 Italian intensive care units during a 3-month period were examined. The scans were collected for neuroradiological review and were used for the analysis together with data from a multicenter database (Neurolink). A review committee found a high incidence of tSAH (61%) in patients with TBI and a moderate agreement among centers (K = 0.57). Significant associations were observed between the presence and grading of tSAH and patient outcomes, and between the presence of tSAH and the severity of the CT findings. Logistic regression analysis showed that the presence of tSAH and its grading alone do not assume statistical significance in the prediction of unfavorable outcome. Conclusions. Traumatic SAH frequently occurs in patients with TBI, but it is difficult to detect and grade. Traumatic SAH is associated with more severe CT findings and a worse patient outcome.

Cystic Meningiomas

✓ Meningiomas have been reported to have associated areas of surrounding low density on computerized tomography (CT). These low-density areas may represent edema, widened subarachnoid spaces, loculated cerebrospinal fluid, demyelination, or adjacent tumor. Two cases are presented in which this adjacent area of low density represented a tumor cyst. Recognition is important as the CT appearance of these lesions may simulate a metastatic tumor.

✓ Demonstration of the exact site of dural fistulas in cases of cerebrospinal fluid rhinorrhea is difficult. Previous reports have described the use of metrizamide cisternography combined with either hypocycloidal tomography or computerized tomography; however, direct, dynamic, real-time visualization of the fistula is difficult with instillation of a minimal dose of metrizamide using those methods. A digital video subtraction fluoroscopy system can visualize the actual site of the fistula directly and dynamically using only a small amount of metrizamide.

✓ In a series of 48 patients with acoustic neurinoma removed by the suboccipital route, one patient developed cerebrospinal fluid rhinorrhea and another patient had delayed-onset meningitis. Each complication was attributed to opening the posteromedial air-cell tract in the posterior wall of the internal auditory meatus. In operations requiring removal of the posterior meatal wall, it is important to look for the air-cell tract which may not be apparent on computerized tomography. If the tract is opened the cells should be occluded by bone wax.

✓ The authors describe their technique for identifying and localizing posttraumatic cerebrospinal fluid fistulas. The method entails injection of radionuclide tracer into the subarachnoid frontal space with the patient in a sitting position followed by gamma camera scintigraphic recordings. The results in 308 patients are presented; these are compared with those of suboccipital radionuclide cisternography in 40 cases and metrizamide computerized tomography cisternography in nine cases. Transient complications occurred in only three patients.

✓ Two cases of intradural disc rupture are presented, and 43 cases found in the literature are reviewed. Dandy's original observations concerning this lesion correlate well with contemporary experience. Characteristics of the history and physical findings are uniform enough to suggest a clinically identifiable syndrome. Microscopic examination of the Cytospin cerebrospinal fluid specimen and the use of computerized tomography with metrizamide may suggest the diagnosis preoperatively. Despite significant neurological deficits associated with lumbar lesions, the prognosis following surgery is good.
