Infantile spinal extradural schwannoma: A rare occurrence

Abstract

In comparison to spinal intradural and intradural–extradural schwannoma, purely extradural schwannoma is rare. There is no clearcut consensus about the origin of these tumors. There are very few cases reported in the pediatric population. On literature search, we have not found a similar case in the infantile age group. We report a case of purely spinal extradural schwannoma in a 5-month-male child who presented with paraparesis. Magnetic resonance imaging scan revealed a 7.5×2.5×1.2 cm size contrast-enhancing spinal extradural mass lesion extending from D4 to D10 vertebral level. The child underwent thoracic laminotomy, and the spinal extradural mass lesion was completely excised. Histopathological examination of the specimen revealed schwannoma. The child recovered well in the post-operative period. At 1 year follow-up, he has completely regained his power in both lower limbs.
