Familial juvenile type III spinal cord arteriovenous malformation: urodynamic findings

Two sisters with juvenile type III spinal cord arteriovenous malformations were studied urodynamically. Micturitional dysfunction was prominent in the clinical presentation of both cases. Although both patients had similar lesions 1 demonstrated detrusor-sphincter dyssynergia and detrusor hyperreflexia, while the other showed only detrusor hyperreflexia. This is the first report of a familial occurrence of juvenile type III arteriovenous malformation and of the associated urodynamic findings.
