✓ The authors describe their microsurgical lateral orbital approach to intraorbital tumors. In seven patients ultrasonic scanning, computerized axial tomography, polytomography, orbital venography, and arteriography have allowed precise intraorbital tumor localization relative to the optic nerve. The authors believe that circumscribed tumors superior, lateral, or inferior to the optic nerve can be safely and completely removed through a 30–35-mm lateral skin incision with microsurgical dissecting techniques. A combined neurosurgical-ophthalmological team approach is emphasized.

✓ Six cases are presented to show that the intracranial arterial spasm accompanying subarachnoid hemorrhage can be associated with an abnormal brain scan beginning 1 to 3 weeks after the onset of the spasm. The scan abnormality gradually disappears over a few months, and is presumably due to cerebral infarction.

✓ Currently available diagnostic tracers for brain tumors are not specific. Tumor-specific tracers would improve the detection of brain tumors by gamma encephalography. Glucose is an important substrate for tumor metabolism and is known to be taken up in large amounts. The authors have studied five labeled carbohydrates in an attempt to find a tumor-specific tracer: three were tritiated (L-galactose-1-3H, L-fucose-3H, and 4,6-dideoxy-xylo-hexose-3H) and two were radioiodinated (methyl-6-125I-6-deoxy-D-glucoside and 6-125I-6-deoxy-D-glucose). The uptake of these tracers by a transplantable mouse ependymoblastoma after intravenous injection was determined by liquid and well scintillation counting. The highest tumor-to-brain ratio was 7.1 to 1 for the tritiated tracers and 6.2 to 1 for the radioiodinated tracers. Although these ratios are not high enough for gamma encephalography, one of the iodinated tracers may be useful for enhancement of contrast in computerized axial tomography.

✓ The authors present the cases of two young adults with low-grade astrocytomas limited to the aqueductal region of the tectum of the mesencephalon. The characteristic presentation of hydrocephalus without brain-stem signs is described. Careful radiological examination, including computerized axial tomography, failed to reveal any evidence of tumor. The diagnosis was established at postmortem examination. Literature review yielded 12 previous cases of similar presentation.

✓ The authors present a case in which primary Ewing's sarcoma of the right petrous pyramid in a 9-year-old girl showed no uptake on a 99mTc-pertechnetate nuclide angiogram. Intense uptake was present on a 99mTc-polyphosphate bone scan, but a static brain scan was only minimally abnormal. The diagnosis and treatment of Ewing's sarcoma are reviewed.

✓ Eighteen patients with chronic subdural hematomas were studied by both brain scans and echoencephalography. All cases were verified by cerebral angiography. Brain scanning was accurate in predicting hematomas in 93% of the cases, and echoencephalography in 44%. When hematomas were bilateral or when frontal clots caused no shift in the diencephalic midline, the routine echoencephalogram often was negative. The two procedures are complementary, and serial studies may be helpful in the study of changing clinical situations.

✓ The authors compared radionuclide cerebral dynamic studies, brain scans, and clinical evaluation as indicators of recurrence of intracranial anaplastic gliomas and found cerebral dynamic studies more sensitive to tumor growth than static brain scans. The former may show changes prior to clinical evidence of tumor progression.

✓ The results of posterior fossa brain scanning in 37 patients with proven posterior fossa tumors were reviewed. Pertechnetate-99m was used as the scanning agent, and attention was paid to careful positioning of the patient. Perchlorate was used to block the parotid gland. The overall detection rate was 78%, particularly good results being obtained with meningiomas, ependymomas, juvenile astrocytomas, metastases, and acoustic neuromas, in that order.
