Large bone defects and lipoma beyond the bone defects are shown. The spinous process of the lower lumbar spine is hypoplastic and the vertebra fusion is incomplete. Two black arrows show the soft tissue continuity from the skin to the lipoma. Two white arrows show the cessation of tissue continuity from the lipoma to the cephalad soft tissue
