How to Explore Fetal Sacral Agenesis Without Open Dysraphism: Key Prenatal Imaging and Clinical Implications

Abstract: The estimated prevalence of fetal caudal dysgenesis is 1 per 100,000 births. The functional prognosis of sacral agenesis is dominated by the large spectrum of associated caudal malformations. Except for cases associated with hydrocephalus secondary to open spinal dysraphism or chromosomal anomalies, association with mental deficiency is rare. We propose a systematic prenatal approach to cases of fetal sacral agenesis based on 9 etiologic items: clinical context, type of sacral dysgenesis, associated spinal cor… Show more

“…It is recognised that early fetal MRI is the gold standard in detecting CRS [21,22]; but in the Low and middle income countries 'context patients do not attend prenatal visits and if attended they cannot have access to such imaging tools. That is why in some studies like ours CRS is diagnosed in the neonatal period in most cases, in the childhood and some exceptions in the adulthood.…”

“…La agenesia caudal es un desorden complejo del desarrollo espinal, que no involucra únicamente las alteraciones del sacro y cóccix, sino también los componentes neural, gastrointestinal y urológico. Tiene su origen embriológico en la alteración del desarrollo de la eminencia caudal, la notocorda caudal y neurulación secundaria, lo que explica la gran variedad de fenotipos de la enfermedad (1)(2)(3) . Puede presentarse como ausencia parcial o total de los cuerpos vertebrales del cóccix, sacro, columna lumbar o torácica, con un grado variable e inconstante de malformaciones espinales, nefrourológicas, anorrectales o cardiacas.…”

“…Puede presentarse como ausencia parcial o total de los cuerpos vertebrales del cóccix, sacro, columna lumbar o torácica, con un grado variable e inconstante de malformaciones espinales, nefrourológicas, anorrectales o cardiacas. En ocasiones, forma parte de síndromes tales como VATER (siglas en inglés de vertebral anomalies, anal atresia, tracheo-esophageal fistula, renal/radial anomalies), OEIS (omphalocele, cloacal exstrophy, imperforate anus, spinal defects) y Currarino (triada de agenesia sacra, masa presacra y anomalía anorrectal) (1)(2)(3) .…”
