3.1 | Neurological symptoms of SDAVF
A typical patient with SDAVF has symptoms associated with thoracic
myelopathy, epiconus syndrome, and conus medullaris syndrome1. Thoracic myelopathy includes motor weakness of the
proximal lower extremities, posterior funiculus dysfunction, and
exaggerated deep tendon reflexes. Epiconus syndrome encompasses a
gradual onset of numbness that initiates in the distal regions of the
lower limbs, and progresses upward. Conus medullaris syndrome includes
bowel and bladder dysfunction. Claudication has been associated not only
with walking but also with bathing, drinking, sleeping, gardening, and
even singing 1, 3. These symptoms are specific to
SDAVF and differ significantly from those of spinal stenosis1, 3. If symptoms cannot be explained by common spinal
stenosis, the possibility of SDAVF should be considered.
