Summary Two weeks after trauma a young man developed signs and symptoms of cervical radiculopathy and myelopathy. Myelography revealed an extradural mass in the spinal canal at the cervicothoracic junction. At operation an epidural hematoma was found, the pathological features of which suggested that it had been present since the injury. This case is exceptional in that spinal epidural hematomas are nearly always associated with rapidly progressing neurological syndromes.

USA Summary A young man presented with visual loss and field changes suggesting direct chiasmal compression by a neighboring neoplasm. Contrast radiography demonstrated obstructive hydrocephalus secondary to a pineal tumor. The markedly dilated third ventricle was intrasellar in location and was causing chiasmal compression. The radiological and ophthalmological findings are discussed and correlated with of the operative findings with a review of the pertinent literature.

Hawkins Department of Neurological Surgery and Radiology Addenbrooke's Hospital Hills Road Cambridge England Summary The results of a retrospective review of the clinical and radiological records of 63 patients with proven cerebral arteriovenous malformation are reported. Patients with dural arteriovenous malformations, and malformations with atypical angiographic features were excluded from the study. Of these 63 patients, 52 had a proven or suspected subrachnoid haemorrhage and 8 patients showed angiographic evidence of cerebral arterial spasm. Two of these patients had an associated intracranial aneurysm and were excluded from the study. The other 6 patients were shown to have spasm between two to thirteen days after a subarachnoid haemorrhage. The incidence of vasospasm associated with subarachnoid haemorrhage in this series was at most 12%. The probable explanation for the relative rarity of vasospasm associated with arteriovenous malformations of the brain, reported by other authors and confirmed by this study, is that the majority of these malformations are peripherally or deeply situated and subarachnoid bleeding is less likely to reach the base of the brain where arterial spasm mainly occurs as compared with haemorrhage from an aneurysm arising from the circle of Willis.

Skalpe Department of Neuroradiology Ullevål Hospital Oslo Norway Summary Fifteen cervical myelographies were carried out with the nonionic watersoluble contrast medium metrizamide. The medium was injected by a lateral puncture between the laminae of the first and second cervical vertebrae. The quality of the radiographs was good. Minor, insignificant side effects were observed in a few patients, but neither the puncture nor the contrast medium caused any serious complications.

Bergquist Department of Diagnostic Radiology University Hospital Uppsala Sweden Summary A patient in whom the posterior temporal and internal occipital branches of the posterior cerebral artery originated separately from the carotid siphon is reported. The possible embryological mechanism underlying this anomaly is discussed.

Oberson Department of Radiology University and State Hospital Lausanne Switzerland Section of neuroradiology Kantonsspital Institute for medical radiology CH-4000 Basel Switzerland Summary The bone changes observed in 7 cases at the site of origin of meningiomas of the anterior chiasmatic angle are described. These consist of intracranial hyperplasia of the sphenoids and/or the posterior ethmoid sinus cells (pneumosinus dilatans) with additional hyperostosis. The upward deformity of the usually straight sphenoethmoidal line seems easier to recognize than hyperostosis on a lateral plain skull film. Special attention is drawn to the problem of early diagnosis.

Germany Abstract A 14 year old child who had three episodes of subarachnoid haemorrhage, was found by spinal arteriography to have a cervical extramedullary arterial aneurysm combined with an intramedullary arteriovenous angioma. The source of the bleeding, the aneurysm, was excised surgically but the intramedullary arteriovenous angioma was not accessible for operation.

Scotti Department of Radiology, Neurological Clinic University of Milan Italy Summary The incidence of the pseudonotch or canal of the medial portion of the lateral masses of the atlas has been studied in 100 normal subjects and in 20 patients with anomalies at the craniovertebral junction. This was found bilaterally or unilaterally in 49% of normal subjects; it is significantly more frequent in elderly than in younger subjects. In the pathological group it was found in half the patients with abnormalities of the occipital vertebra while it was apparently more rare in patients with occipitalization of the atlas.

Sereghy Research Institute of Rheumatology, Faculty of Preventive Medicine Charles University Prague Czechoslovakia Neurological Clinic, Faculty of Preventive Medicine Charles University Prague Czechoslovakia Summary An analysis of 102 PDGs is given with regard to the anatomy of the peridural spaces and of 98 PDGs verified at operation as to their diagnostic value. The anatomical picture and its variations (including anomalies and some pathological findings) are explained by the geometrical shape of the lumbosacral spinal canal which is oval in the upper, triangular in the lower lumbar and slit-like in the sacral region. From the anatomical analysis, as well as from our clinical material, it can be deduced that PDG has about the same diagnostic value as PMG, offering the advantage of the extradural application of contrast material, i.e. harmlessness and applicability in out-patients.
