Multiple cerebral arteriovenous malformations--case report.

Multiple cerebral arteriovenous malformations occurred in a 48-year-old male complaining of headache, after orthopedic treatment for a leg fracture. He was free from neurological deficits and signs of hereditary hemorrhagic telangiectasia. Postcontrast computed tomography showed two abnormally enhanced lesions in the right occipital and left parietal regions. Magnetic resonance imaging showed these lesions as tiny vascular flow void signs, with neither new nor old hemorrhages. Angiography showed these lesions to be arteriovenous malformations. He declined treatment, and was followed as an outpatient.
