Radiological investigations include plain and contrast radiographs, ultrasound, computed tomography and magnetic resonance imaging (MRI). ‘Scimitar’ sign, a smooth curved unilateral sacral defect simulating shape of Arabic sabre on plain X-ray, is considered to be pathognomonic of ASM ¹⁾.

Contrast enema, which may show displacement of rectum, sigmoid colon and urinary bladder, is now obsolete for diagnosis. Abdominal and spinal sonography should be the first diagnostic investigation and can diagnose ASM and differentiate it from other cystic lesions in the pelvis ²⁾.

Imaging for screening for ASM and presacral teratoma should be directed at identifying the presacral mass rather than sacral bony defect. Thus computed tomography or MRI is recommended as the screening modality ³⁾.
