ABSTRACT: The management of anorectal atresia depends on the level of the lesion and the presence of fistulae or associated genitourinary and sacral anomalies. If the lesion is low and the infant is well then a primary anoplasty may be performed in the early neonatal period. However, for high or intermediate lesions an initial colostomy followed by definitive repair later is recommended. We report a newborn infant with anorectal atresia investigated at six hours of age using MRI to locate the level of atresia. Conventional x-ray utilises bowel gas as contrast to outline the terminal section of the gut. Hence, x-ray is often not performed until 18 hours when adequate gas, to provide contrast, is present in the distal bowel. MR imaging utilises the high signal of meconium on T1 weight scans to delineate the terminal section of the bowel thus removing the need to wait for a delayed plain radiograph. This enables a decision to be made regarding the surgical procedure before the distal bowel is gas filled, hence, the bowel is in better condition for surgery. A further advantage is that it may confirm the presence of associated anomalies including accompanying fistulae and spinal or renal tract malformations.
