Duplicate filum terminale noted in an adult: A rare finding

Abstract

This is the first reported case of an adult presenting with tethering symptoms, limb discrepancy on physical examination, a low-lying spinal cord, and duplicate filum terminale discovered intraoperatively. Intraoperative imaging and pathological analysis of a specimen confirmed the diagnosis of duplicate filum. This is the first reported adult case with duplication of the filum terminale. Release of both fila was necessary in this case to relieve the tethering symptoms.
