One-month-old male infant presented with low back fatty swelling and ARM. A Sagittal T2WI showing agenesis of S3, 4, 5 sacral elements and coccyx in keeping with sacral agenesis type II (white arrow). B Midline sagittal T2WI showing low lying conus medullaris ending at level of L3–4 disk yet with normal tapering appearance (black arrow), note also evidence of high-level ARM; above puborectalis muscle, with rectourethral fistula (Black empty arrow). C Sagittal T1WI showing herniation of subcutaneous fat through dural defect into spinal canal (white arrow). D Sagittal T1WI showing lipoma-placode interface outside spinal canal (star). E Sagittal USG image showing conus medullaris tip at level of L4 (black arrow), with subcutaneous fatty mass seen herniating into spinal canal (white arrow). F Axial USG image showing herniation of neural placode (dashed arrow) outside the confinement of spinal canal (curved black arrow, lamina). G Axial USG image at level of L4 showing lamina (white arrows), epidural fat (star) and cauda equina nerves (black arrow). Type of spinal dysraphism: Lipomyelomeningeocele with partial sacral agenesis
