234 24 24 4 4 A. Valavanis J. Wellauer M. G. Yaşargil Department of Diagnostic Radiology University Hospital Zurich Switzerland Department of Neurosurgical Clinic University Hospital Zurich Switzerland Summary The angiographic and CT findings in seven cases of cerebral venous angioma are presented and analyzed. Two cases were also examined with dynamic CT. The radiological literature on the subject is reviewed and a new classification of cerebral venous angioma based on its pattern of drainage is proposed. It is concluded that with the use of thin slices and coronal cuts both the angioma and its pattern of venous drainage can be indentified on CT in a high proportion of cases. In addition, with dynamic CT the specificity of CT in diagnosing cerebral venous angioma may further increase.

234 24 24 4 4 S. Holtås S. Cronqvist T. Renaa Department of Diagnostic Radiology, Section for Neuroradiology University Hospital Lund Sweden Medical Department Nyegaard & Co. Stockholm Sweden Summary The new non-ionic contrast medium iohexol was compared with Amipaque in selective cerebral angiography in a double blind study in 60 patients. There were no adverse reactions or reports of discomfort during the examinations or in the 24 h follow-up period. No differences were observed with regard to image quality or cerebral circulation time.

Kaude Department of Radiology University of Florida College of Medicine Gainesville Florida USA Department of Pediatrics University of Florida College of Medicine Gainesville Florida USA Summary This study focuses on comparison of computed tomography and ultrasound in premature infants with intracranial hemorrhage and its complications. It was determined that close correlation (95%) exists between CT and ultrasound for evaluation of ventriculomegaly. Although there is reasonable correlation for the identification and localization of periventricular, intraventricular and choroidal hemorrhages, ultrasound defined such lesions at higher rates. Subarachnoid blood and periventricular edema were diagnosed better or exclusively by CT.
Contrast enhanced brain CT comparison between iohexol and metrizoateHoltås, S.; Cronqvist, S.; Renaa, T.

234 24 24 4 4 S. Holtås S. Cronqvist T. Renaa Department of Diagnostik Radiology, Section for Neuroradiology University Hospital Lund Sweden Medical Department Nyegaard & Co. Stockholm Sweden Summary The commonly used contrast medium metrizoate (isopaque Cerebral ® ) or the new nonionic iohexol were injected intravenously for enhancement of cranial CT in a randomized double blind study. Each group consisted of 105 patients. No serious reactions occurred. Ten patients receiving metrizoate had minor reactions of mainly allergic type, whereas only one patient receiving iohexol reacted. No differences in enhancement efficiency could be observed.
The toxicity of non-ionic water-soluble monomeric and dimeric contrast media in selective vertebral angiographySkalpe, I.

234 24 24 4 4 I. O. Skalpe Institute for Clinical Medicine University of Tromsø Tromsø Norway Department of Roentgenology University Hospital N-9012 Tromsø Norway Summary Selective vertebral angiography was performed in 29 rabbits in order to compare the adverse effects of three monomeric (iopamidol, iopromide, metrizamide) and one dimeric (iodecol) non-ionic water-soluble contrst medium. The dose was 10 ml and the iodine concentration 350 mg/ml. Marked, but transitory changes were seen in the electrocardiographic and blood pressure recordings with all the contrast media. The monomers seemed to have a higher tendency than the dimer to cause spasm in the intracranial arteries, while the changes in the cardiovascular recordings were more marked with the dimer. One animal died and one animal developed a permanent neurological deficit following the injection of the dimer. All the other animals recovered completely and seemed quite unaffected within half an hour after completion of the experiment.
Solitary metastasis of systemic malignant lymphoma to the cerebellopontine angleNakada, T.; John, J.; Knight, R.

Knight Department of Neurology University of California, Davis, Veterans Administration Medical Center Martinez California USA Department of Neurosurgery University of California, Davis, Veterans Administration Medical Center Martinez California USA Summary Systemic malignant lymphoma rarely produces solitary metastasis to the brain. We report such a case in the cerebellopontine (CP) angle mimicking an acoustic neurinoma. CT scan showed a large, round mass in the CP angle which enhanced homogeneously following contrast infusion. The internal auditory meatus appeared to be eroded. The clinical, radiological, and pathological findings are presented.
CT in a case of intracranial penetration of a pencilKaiser, M.; Rodesch, G.; Capesius, P.

234 24 24 4 4 M. C. Kaiser G. Rodesch P. Capesius Department of Radiology Centre Hospitalier Luxembourg Luxembourg-City, Grand-Duchy of Luxembourg Summary A case is reported of an unusual foreign body, a pencil, penetrating the right temporal lobe through the squamous temporal bone in a fall. Wood has low attenuation coefficients, so that the appropriate CT examination includes multiple window settings to permit accurate assessment of bone fragment displacement as well as recognition of detached wood splinters. CT scanning and early surgery are important steps in the management of these injuries to reduce significantly the overall mortality as well as immediate and long term complications. The necessity for meticulous surgical technique when removing the foreign body is stressed as retained wood can not easily be visualized against the hypodense background due to postoperative changes.
