Fifteen cases of intervertebral disc calcifications have been diagnosed in Umeå during a period of 14 years. In the literature up to now about 100 cases of intervertebral disc calcification have been reported. Our findings suggest that these calcifications are not as rare as has been stated. There are both symptomatic and silent cases. When present the(More)
In a series of 715 patients operated on by microsurgical techniques for intracranial saccular aneurysms between 1970 and 1980, part of the aneurysmal sac was not obliterated in 28 aneurysms in 27 patients (3.8% of 715 cases). Clinical follow-up evaluation for 8 years (range 4 to 13 years) and angiographic follow-up studies for 6 years (range 2 to 10 years)(More)
PURPOSE Two new signs of lumbar nerve-root affection have been reported in recent years on the basis of MR examinations, namely: thickening in nerve roots; and contrast enhancement in nerve roots. The aim of this study was to assess contrast enhancement in nerve roots in a standardised way, and to evaluate the clinical significance of contrast enhancement(More)
OBJECTIVE To study the results after fractionated radiotherapy of large arteriovenous malformations (AVMs). METHODS Twenty-eight patients harboring large AVMs were treated between 1980 and 1985 with fractionated radiotherapy with up to 3.5 Gy per fraction twice a week to a total dose of 41 to 50 Gy. All but 5 patients were examined with an angiogram at(More)
Recurrences of erysipelas are especially prevalent in patients suffering from local impairment of circulation and intervention might thus be of benefit. Therefore a prospective, randomized, open study was undertaken to evaluate whether daily antibiotic prophylaxis would reduce the risk of recurrence. Patients with venous insufficiency or lymphatic(More)
CT scans have been made on 39 of 41 patients who presented with subarachnoid hemorrhage. Blood could be visualized in the cisterns of 18 of 32 examinations performed within five days of the hemorrhage all having aneurysms. Among the other 14 there were three in whom no aneurysm was found on angiography. The distribution of blood in those that showed it was(More)
The authors report outcomes in 18 patients with arteriovenous malformations (AVMs) who were treated with gamma knife radiosurgery and in whom magnetic resonance (MR) imaging was obtained a mean of 14 years (range 8-23 years) after treatment and 10 years (range 4-17 years) after confirmed obliteration of the AVM. All patients were asymptomatic after(More)
The reports of rupture of an aneurysm during carotid angiography are very few but the actual incidence is doubtless higher than recorded. The case presented is documented with the demonstration of a large middle cerebral artery aneurysm with an intratemporal hematoma, and, in sequence, the rupture of the aneurysm during the height of the injection and the(More)
Gamma knife radiosurgery is an effective alternative to embolization or microsurgical removal of small arteriovenous malformations, particularly in eloquent areas of brain tissue. Stereotaxic angiography is a useful diagnostic and targeting adjunct to gamma knife radiosurgery, and the authors present their experience (1,100 patients) with methods and(More)
