Transient Dorsal Cord Syndrome After Splanchnic Neurolysis: A Case Report

Image-guided splanchnic neurolysis has been performed for decades to relieve abdominal pain due to cancer. Severe complications associated with the procedure are rare but could happen. Different from the previously reported cases of paraplegia due to anterior artery (cord) syndrome, here we presented a case of transient dorsal cord syndrome involving bilateral lower extremities after splanchnic neurolysis.

The patient had numbness and impaired proprioception of both legs, ataxic gait, and bowel and bladder dysfunctions shortly after bilateral splanchnic neurolysis. Magnetic resonance imaging of the spine shows new abnormal signals in the dorsal column. Based on the presentations and image findings, the diagnosis of dorsal cord syndrome was made. The majority of the symptoms were resolved in 2 weeks after the treatment of oral steroids and physical therapy.

Severe neurological complications could happen after image-guided splanchnic neurolysis. Close motoring, early imaging, and multidisciplinary collaboration with different services are strongly recommended to promote a speedy recovery and prevent a permanent deficit.
