Case 10: 2-month-old girl with SSD and associated questionable coccygeal agenesis. Case 10: 2-month-old girl with SSD and associated questionable coccygeal agenesis. A, Lateral radiograph at age 1 day shows severe hypoplasia and posterior dislocation of L2 (arrow) with absence of posterior vertebral elements. There is marked kyphosis in the upper lumbar spine and questionable absence of the coccyx, as its ossification may be incomplete in the neonate.B–D, Sagittal SE (600/20/4) (B) and axial SE (600/16/2) (C and D) T1-weighted MR images at age 12 months show that the upper cord ends at the midthoracic level in a wedge shape (open arrow, B) and contains a thin hydromyelic cavity. Below, no cord is discernible even on the axial images (C and D). At the apex of the kyphosis, the spinal canal is extremely narrowed (black arrow, B). Below, a bulky, low-lying lower cord is visible in the thecal sac (white arrow, B) and appears to fill it almost completely (D). Paolo Tortori-Donati et al.
