234 18 18 3 3 H. J. Gelmers Department of Neurology, Prinses Irene Ziekenhuis, Almelo and Neurosurgery University Hospital Groningen The Netherlands Summary The adverse side effects in a series of 439 myelographies with metrizamide were analyzed. The most frequent side effect was headache, which could be differentiated as early onset headache, related to hydrodynamic modifications in the spinal fluid following lumbar puncture, and late onset headache related to a metrizamide effect. The frequency of late onset headache was at least 27%, but all together 46% of the patients had postmyelographic headache. Meningeal irritation was seen in 5%, sometimes in a severe form, mimicking a septic complication. Spinal irritation and epileptic fits were rarely seen. Striking was the occurrence of an acute psycho-organic syndrome, frequently observed after cervical myelography which was performed with a higher than usual dose of iodine. We can not confirm the general opinion that the central nervous system has a good tolerance for metrizamide.

U. de Purpan Toulouse France Summary A simplified map of the cervicovertebralcarotid channels is presented with a description of the arterial supply to the cervical nerves. The aim of the work is also to open the field for endovascular therapy of malignant lesions distal to carotid ligation with greatest security, and to discuss a new approach to some upper cervical neuropathies.

234 18 18 3 3 H. van Crevel Department of Neurology Erasmus University, Academisch Ziekenhuis Dijkzigt Rotterdam Netherlands Summary RIHSA cisternography was abnormal in all of 24 patients with supratentorial tumours. The most common finding was asymmetry caused by ipsilateral obstruction of the sylvian fissure and the subarachnoid space around the convexity. Another frequent finding was partial or total obstruction at the tentorial notch, often in combination with reduced or absent activity along the superior sagittal sinus. These disturbances of CSF flow may explain the pathogenesis of raised CSF pressure with cerebral tumours.

234 18 18 3 3 F. Jensen E. Reske-Nielsen E. Ratjen Department of Neurosurgery, Neuropathology and Neuroradiology Aarhus Kommunehospital Aarhus Denmark Summary A case with delayed development of obstructive hydrocephalus most probably caused by Pantopaque myelography is reported. At autopsy it was found that the foramina of Magendi and Luschka were occluded by granulation tissue in which the most common findings were multinucleated giant cells containing calcareous and unstained vacuoles, frequently surrounding empty hollows, many lymphocytes and plasma cells. As compared with two other similar cases and several animal investigations this shows that the reaction of the tissue is typical of a Pantopaque reaction.

234 18 18 3 3 A. R. Valentine Lysholm Radiological Department National Hospital for Nervous Diseases Queen Square London UK Summary Traumatic arteriovenous fistulae, resulting in delayed damage to the cervical spinal cord and roots, are well documented. This report concerns an iliac arteriovenous fistula with damage to the cauda equina.

Vannineuse Neurosurgical Service Centre Hospitalier de Luxembourg Luxembourg Neuroradiological Service Centre Hospitalier de Luxembourg Luxembourg Summary A case of intracerebral extravasation of contrast medium is reported. In cases of head injury this occurrence is rare and is manifested by persistent images on both frontal and lateral views of the angiogram. This indicates severe cerebral trauma with active hemorrhage and the prognosis is generally bad. A possible mechanism seems to be contrecoup.

234 18 18 3 3 O. Flodmark C. R. Fitz D. C. Harwood-Nash S. H. Chuang Department of Radiology, Division of Pediatric Neuroradiology Hospital for Sick Children Toronto Ontario Canada Summary A case of primary leptomeningeal melanoma in a child is presented. The patient was studied with multiple neuroradiological methods, however computed tomography (CT) provided the most important information. The CT findings with leptomeningeal tumor, although not completely specific, do suggest the diagnosis, thus providing important information to explain the acute onset of symptoms in a previously healthy child. This case also differs from previously reported cases in terms of the type of hydrocephalus associated with the tumor.

Lessell Department of Ophthalmology, Neurology and Anatomy Boston University School of Medicine Boston Massachusetts USA Summary A patient with an amyloid tumor of the orbit was studied by computed tomographic scanning. The tumor density was 10 delta units unenhanced and 72 units enhanced.

Chiu Jr. Miriam Christ Department of Radiology Evanston Hospital-Northwestern University Evanston Illinois USA Department of Pathology Evanston Hospital-Northwestern University Evanston Illinois USA Department of Surgery Northeastern Ohio College of Medicine Youngstown Ohio USA Summary Aneurysmal bone cysts occurring within the calvarium are uncommon. The following case report describes the radiological and pathological findings of a temporal bone aneurysmal bone cyst with intra- and extracranial manifestations. The pertinent literature is reviewed.
