case_images: A subcutaneous fluctuation, which seemed to be the size of a large egg, was palpable at the tip of the deformity (Fig. 1a). Five milliliter of bloody serum was aspirated from the fluctuation (Fig. 1b).
case_images: A lateral plain radiogram showing a kyphosis of 35  at T12/L1 (a). Reconstructed CATs demonstrating a fracture line through the spinous process, the pedicle, and the upper vertebral body in the L1 vertebra. A lesion containing gas at the T12/L1 intervertebral disc and the upper vertebral body of the L1 vertebra (b)

case_images: A lateral plain X-ray demonstrated a kyphosis of 35  at T12/L1 (Fig. 2a). T12/L1 intervertebral disc and the upper vertebral body of the L1 vertebra, whereas no bony protrusion was present in the spinal canal at the affected level (Fig. 2b). These investigations suggested a diagnosis of a chronic FDI with a bursitis or hematoma on the split spinous process in L1.
case_images: A subcutaneous fibrous cystic lesion connected with the split L1 spinous (a). Pathological diagnosis was bursitis. H&E: magnification; x40 (b)

case_images: Pathological diagnosis was a bursitis (Fig. 3a, b).
case_images: Plain radiograms demonstrating a solid boney fusion with a minimal kyphosis of 5  at T12/L1 (a and b). Reconstructed CATs showing an intense bone bridging (c and d)

case_images: Plain radiograms and reconstructed CAT demonstrated a solid boney fusion with a minimal kyphosis of 5  at T12/L1 (Fig. 4a-d).
