MR Imaging of Angiographically Occult Vascular Malformations
Eleven patients with 15 angiographically occult arteriovenous malformations were studied by magnetic resonance (MR) imaging and computed tomography (CT). Five patients had biopsy proof; six were clinically diagnosed from the long-term clinical follow-up (more than 3 years) and imaging features. Of the 15 lesions, 11 were recognized by both CT and MR. Each method was falsely negative for two les...
متن کاملAngiographically occult arteriovenous malformations of the brain.
Six patients with cerebral arteriovenous malformations which did not show any pathological circulation at angiography are described. Computed tomogram appearances of such lesions may be difficult to distinguish from tumours. The need for surgical exploration in localised high attenuation lesions of uncertain nature is stressed, and the literature is reviewed.
متن کاملClinical Features of Angiographically Occult Vascular Malformation

The rheumatism clinics may be the first to see those cases in which syphilitic disease has attacked the bones or joints of small infants, older children, teenagers, and adults. Because early infectious syphilis was extremely prevalent during and immediately after the second world w...
متن کاملThe computerized tomographic appearance of angiographically occult arteriovenous malformations of the brain.
Eight patients with a histologically proven angiographically occult arteriovenous malformation of the brain had plain and infused computed tomographic (CT) examinations. In five cases angiography revealed a hypovascular mass in three cases the angiogram was normal. On CT examination a high density lesion (six cases) and ventricular asymmetry (five cases) were demonstrated. In three patients pre...
