✓ The case of a patient with multiple small cerebral gummata presenting with severely raised intracranial pressure is reported. The diagnosis, which was quite unexpected, was based on positive serological tests for syphilis. Computerized tomography (CT) showed small enhancing lesions with intense cerebral edema. The patient was treated successfully with penicillin, and resolution of the lesions was observed on CT scanning over a 1-year period. The importance of “routine” serological testing is noted.

✓ The authors report a case of frontal lobe oligodendroglioma associated with a cavernous angioma. The patient presented with signs and symptoms of raised intracranial pressure. Computerized tomography with contrast enhancement failed to detect the vascular component. The clinical and pathological significance of the presence of this vascular malformation in an oligodendroglioma is discussed.

✓ 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.

✓ Eleven cases of cerebral hydatid cyst, diagnosed by computerized tomography (CT), are presented. The importance of CT in minimizing the possibility of accidentally tapping or tearing the cyst membrane is stressed. Repeat CT scanning after removal of the cyst revealed atrophy in the affected hemisphere.

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.

✓ A healthy young woman developed a rapidly progressive pontomedullary lesion 24 hours after delivery of her first child. The lesion was shown on computerized tomography (CT) to be a primary hematoma. Stereotaxic aspiration was carried out, and the patient recovered. Angiography and CT scanning demonstrated a vascular lesion compatible with an arteriovenous malformation.

Object. The authors confirm the usefulness of extravasation detected on three-dimensional computerized tomography (3D-CT) angiography in the diagnosis of continued hemorrhage and establishment of its cause in patients with acute intracerebral hemorrhage (ICH).Methods. Thirty-one patients with acute ICH in whom noncontrast and 3D-CT angiography had been performed within 12 hours of the onset of hemorrhage and in whom conventional cerebral angiographic studies were obtained during the chronic stage were prospectively studied. Noncontrast CT scanning was repeated within 24 hours of the onset of ICH to evaluate hematoma enlargement.Findings indicating extravasation on 3D-CT angiography, including any abnormal area of high density on helical CT scanning, were observed in five patients; three of these demonstrated hematoma enlargement on follow-up CT studies. Thus, specificity was 60% (three correct predictions among five positives) and sensitivity was 100% (19 correct predictions among 19 negatives). Evidence of extravasation on 3D-CT angiography indicates that there is persistent hemorrhage and correlates with enlargement of the hematoma.Regarding the cause of hemorrhage, five cerebral aneurysms were visualized in four patients, and two diagnoses of moyamoya disease and one of unilateral moyamoya phenomenon were made with the aid of 3D-CT angiography. Emergency surgery was performed without conventional angiography in one patient who had an aneurysm, and it was clipped successfully.Conclusions. Overall, 3D-CT angiography was found to be valuable in the diagnosis of the cause of hemorrhage and in the detection of persistent hemorrhage in patients with acute ICH.

✓ With the advent of computerized tomography (CT), a new method of visualizing the spinal canal in cross-section has been created. Before the introduction of CT scanning, evaluation of the cross-sectional anatomy of the spinal canal was accomplished chiefly by the Toshiba unit. This study compares these two forms of tomography and discusses their relative effectiveness in diagnosing constrictive lesions of the spinal canal.

✓ The nonsurgical treatment of a case of interhemispheric subdural empyema is reported. At the time of diagnosis, the patient had a mild decrease in consciousness and only moderate focal neurological deficits. Computerized tomography (CT) confirmed the limited (interhemispheric) extent of the intracranial infection. After drainage of the nasal sinuses and antibiotic treatment, the patient recovered, although the lesion was initially increased in size on CT scanning.

Cystic Meningiomas

✓ A group of eight cystic meningiomas is considered, with particular reference to preoperative radiological evaluation. Computerized tomography (CT) scanning alone is inadequate for diagnosis, and the authors offer an assessment of the current methods for preoperative identification of cystic supratentorial tumors, while reviewing the multiple etiologies suggested for the CT appearance. No single process explains all the aspects of peri- or intratumoral cyst formation in meningiomas.

✓ Lipomas of the infundibulum are extremely rare and may not be recognized radiologically, even on computerized tomography (CT) scanning, if the tumor is less than 20 mm in diameter. A questionable CT diagnosis in the presence of endocrinological symptoms may justify an operation by microsurgical technique on the retrochiasmatic region. In the case reported, microsurgical removal of a small infundibular lipoma was successfully accomplished.
