Slow-flow spinal epidural AVF with venous ectasias: two pediatric case reports.

We report the clinical and imaging findings in the cases of two children who initially presented with back pain related to epidural AVF in the cervicothoracic spine. Both lesions were of particular interest because of their exclusive epidural and paraspinal venous drainage and the presence of the prominent venous pouches in the epidural space. Angiography revealed that one was multifocal and of relatively slow flow. We think that these unusual features have important implications for treatment.
