Transient Dorsal Cord Syndrome After Splanchnic Neurolysis: A Case Report

Area of Science:

• Neurology
• Interventional Radiology
• Oncology

Background:

• Image-guided splanchnic neurolysis is a long-standing procedure for cancer-related abdominal pain.
• While rare, severe neurological complications can occur post-procedure.
• This report details a unique case of transient dorsal cord syndrome following splanchnic neurolysis.

Observation:

• A patient developed bilateral leg numbness, impaired proprioception, ataxic gait, and bowel/bladder dysfunction post-procedure.
• Spinal MRI revealed new abnormal signals in the dorsal column.
• Clinical presentation and imaging confirmed dorsal cord syndrome.

Findings:

• The patient experienced transient neurological deficits affecting bilateral lower extremities.
• Symptoms resolved within two weeks with oral steroids and physical therapy.
• This contrasts with previously reported anterior artery (cord) syndrome complications.

Implications:

• Image-guided splanchnic neurolysis carries a risk of severe neurological complications.
• Close patient monitoring and prompt neuroimaging are essential.
• Multidisciplinary collaboration aids in preventing permanent deficits and promoting recovery.
