Eight-month-old male infant presented with upper dorsal atypical skin dimple (crater) associated with cardiac congenital anomaly (TGA). A An upper dorsal cutaneous deep wide dimple (crater) with mild hypertrichosis. B Sagittal MRI T2WI showing fibrous tract extending from skin surface at level of D1/D2 vertebrae passing deeply into spinal canal with tethering and slight tenting of spinal cord at that level (black arrow), dorsal CSF flow artifact (star). C Axial MRI T2WI showing the fibrous tract passing though spinal bifida of D2 vertebra (black arrow) with minimal syrinx at that level (curved black arrow). D Sagittal USG image showing minimally dilated central canal (black arrow). E Axial USG image showing the fibrous tract extending from skin surface into spinal canal. F Sagittal T2WI at level of lumbar spine showing conus tip at level of L2 vertebrae (black arrow) with relatively thickened filum terminale. G Axial T2WI showing thickened filum terminale (white arrow). H, I Axial and Sagittal USG images showing thickened echogenic filum terminale measuring 2.1 mm. J M mode USG image at L5-S1 level showing absent movement of nerve roots. Type of spinal dysraphism: Dorsal LDM with focal syrinx and tight filum terminale
