Abstract: Objective:To explore the imaging features of sacral agenesis in children and the role of CT and MRI in diagnosing this disease.Methods:19 cases of sacral agenesis were retrospectively analyzed,8 male cases and 11 female cases.All cases were examined with MRI,and 6 cases of which underwent spiral CT scanning simultaneously.Results:According to the appearance of the residual sacrum,all patients were classified into 3 types,9 cases belonging to typeⅠ,9 typeⅡ and 1 case type Ⅲ.Meanwhile,upper spinal malformations were shown in 10 cases.Spinal cord deformities were found in 18 patients,and 12 of which showed the signs of tethered cord syndrome.In addition,renal malformations were found in 6 cases,neurogenic bladder in 2 cases.Conclusion:Spiral CT combined with MRI can exactly manifest the appearance of the sacrum,spinal cord,nerve roots and other deformities of the affected children,hence being more helpful in diagnosing sacral agenesis.
