Apéndice cutáneo sacro asociado a lipoma del filum terminal y médula anclada: un caso de diagnóstico prenatal Translated title: Sacral cutaneous appendage associated with lipoma of the filum terminale and anchored medulla: a case of prenatal diagnosis

Abstract

RESUMEN Los disrafismos espinales cerrados tienen una prevalencia aún desconocida e involucran una gran variedad de formas. El lipoma del filum terminal es considerado dentro de los lipomas espinales y suele asociarse a médula anclada. Los estigmas cutáneos lumbosacros no siempre son indicadores de disrafismo espinal cerrado. Reportamos un caso de diagnóstico prenatal de apéndice cutáneo sacro con sospecha de médula anclada, confirmado al nacer como lipoma del filum terminal con médula anclada.

Translated abstract

ABSTRACT Closed spinal dysraphisms have a still unknown prevalence and involve a wide variety of forms. Lipoma of the filum terminale is considered within spinal lipomas and is usually associated with tethered medulla. Lumbosacral cutaneous stigmata are not always indicative of closed spinal dysraphism. We report a case of prenatal diagnosis of sacral cutaneous appendage with suspected tethered cord, confirmed at birth as lipoma of the filum terminale with tethered cord.
