Plexiform neurofibroma of the cauda equina. Case report.
J Neurosurg. 1999 Jul; 91(1 Suppl):112-5.JN

Abstract

Plexiform neurofibroma of the cauda equina has been reported only twice previously. The authors report the first pediatric patient in whom such a tumor has been found. A 4-year-old boy presented with low-back pain that radiated bilaterally into the L-4 and L-5 dermatomes. A dermal sinus noted at the midthoracic level was surrounded by a hemangiomatous lesion. Magnetic resonance imaging confirmed the presence of the dermal sinus and revealed a well-defined lumbosacral mass that showed heterogeneous intensity with irregular enhancement. Intraoperatively, a solid mass, which engulfed the entire cauda equina, could not be dissected from the roots. The dermal sinus tract, however, was excised from the thoracic spine. The patient underwent radiotherapy to control the tumor and relieve his pain. Plexiform neurofibromas of the cauda equina are characterized by an insidious and progressive clinical course. The tumor mass may engulf all the roots of the cauda equina. No plexiform neurofibroma of the cauda equina has been reported to be associated with neurofibromatosis Type 1. The authors assume that the thoracic-level dermal sinus observed in this child was an incidental finding.
