Seven pontine angle meningiomas were examined with computed tomography (CT). The result was compared with that of a study of 61 acoustic neuromas. These two tumor types differ in manner of growth, volume, shape,attenuation, attachment to bone, cisternal deformation, frequency of calcification, peripheral edema, and bone changes.
Sixty-one acoustic neuromas were examined with computed tomography (CT). For differential diagnosis the tumors were thoroughly analyzed for manner of growth, shape, volune, calcification, attenuation pattern, contrast enhancement, presence of peripheral edema, and cisternal deformation.
To eliminate the occurrence of artefacts produced by clips on the CT images, the use of titanium clips is suggested. Testsin vitro andin vivo indicate that clips manufactured from 0.2 mm thick 99.9 per cent titanium do not cause artefacts. They are resistant to corrosion, nontoxic, effective, easy to handle, relatively cheap, and are visible on plain X-ray… (More)
The changes of the enhancement of the lesion with time after intravenous administration of contrast medium were measured with computed tomography (CT) in 23 cases of acoustic neuroma. The pattern of high initial enhancement followed by a fairly rapid decrease is confirmed. A more rigorous study of the enhancement pattern using a mathematical description of… (More)
Forty-seven patients with 48 nonoperated acoustic neuromas have been studied by computed tomography (CT) with respect to bone changes. CT and conventional X-ray examination of the skull were compared. The importance of using a small collimator, proper selection of the plane of the CT section, and changing of the window level is stressed. CT detects porus… (More)
Chronic microvascular compressions of the eighth nerve induce a slowing down of signal transmission in the auditory nerve, electrophysiologically characterized by IPL I-III prolongation. The authors hypothesize this is compensated by an active slowing down of signal transmission of the contralateral input at the level of the brainstem, characterized by… (More)

At the time of operation advanced carcinomas of the urinary bladder often have developed subclinical metastases. In 20 patients with metastases, inoperable carcinoma of the bladder responded to chemotherapy with a combination of adriamycin and 5-FU. 55% of the patients experienced either a complete or incomplete remission, which lasted long in some cases.… (More)
Encapsulated pleural effusion was investigated radiographically in 4 patients by injection of a non-ionic water-soluble contrast medium (Amipaque) into the encapsulated site. Demonstration of the presence and extent of the cavities and their size and form was thereby achieved.
