ABSTRACT

Objective: To review main clinical Magnetic resonance applications in congenital malformations of the spinal cord in pediatric patients.
Materials and methods: One LG of 1.5 tesla Resonance-Compatible Incubator was used. 95 cases turned to the Pediatric National Institute (Instituto Nacional de Pediatría) between March 10, 2005 and August 25, 2007. According to the Department protocol, images of sagital, coronary and axial planes were obtained with relaxing times in T1, T2 with gadolineum and myelographic effect.
Results: Of the 95 children, 40% showed spinal cord anomalies, from which, in frequency showed: open and occult spinal dysraphism. 30 (70%), disorders derived from non disjunction 15 (39%), disorders derived from premature disjunction 8 (21%), anomalies of the caudal cell mass 10 (26%), malformations of the medulla division 5 (13%).
Conclusion: Magnetic resonance proves pathological anatomical changes in the pediatric spinal cord. Boys predominated compared to girls 4-2 associated to anorectal and genitourinary malformations. Sacrum and spinal cord were thoroughly evaluated since most of spinal dysraphysms were associated to Tethered cord syndrome showed lesser gastrointestinal and urogenital alterations, as VACTERL. MR is a non-invasive method and an optimal technique for the post-operation follow up of these patients.
