Angiographically 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 کاملMR 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 کاملClinical Features of Angiographically Occult Vascular Malformation
=Abstract=A retrospective review of 22 cases of angiographically occult vascular malformations (AOVMs), treated at our institution during the past 6 years, was conducted to define better the clinical and radiological manifestations as well as the effective treatment modality of these lesions. There were 12 (54.5%) arteriovenous malformations (AVMs), 8 (36.4%)cavernous angiomas, 1 (4.5%) venous ...
متن کاملGlioma coexisting with angiographically occult cerebrovascular malformation: A case report
Angiographically occult cerebrovascular malformation (AOVM) is a type of complex cerebrovascular malformation that is not visible on digital subtraction angiography (DSA). Vascular malformation coexisting with glioma is clinically rare, and glioma coexisting with AOVM is even more rare. To the best of our knowledge, the present study is the first to report glioma coexisting with AOVM in the lit...
متن کاملAngiographically occult arteriovenous malformation in the septal region--case report.
An occult arteriovenous malformation (AVM) in the septal region occurred in a 14-year-old boy, manifesting as headache and vomiting. Computed tomography showed a high-density mass in the septal region, faintly enhanced postcontrast. Mild hydrocephalus was also seen. Angiography revealed no abnormalities other than hydrocephalic signs. The lesion was totally removed by the transventricular appro...
