Early diagnosis of thoracic spinal dural arteriovenous fistula using lumbar magnetic resonance imaging: A case report

Abstract

In middle-aged and older men, clinicians often suspect lumbar spine disease when gait is impaired with intermittent claudication, but spinal dural arteriovenous fistula (SDAVF) may be the etiology. An understanding of the key magnetic resonance imaging findings of SDAVF is necessary for early diagnosis, appropriate treatment, and minimization of complications.
