FIG 2. Images of a 79-year-old man with back pain.

A, Pre-vertebroplasty sagittal view T1-weighted MR image shows bone marrow edema of T12 and L1.

B, Pre-vertebroplasty sagittal view T2-weighted MR image shows bone marrow edema of T12 and L1.

C, Sagittal view contrast-enhanced T1-weighted MR image shows enhancement, indicating acute T12 and L1 compression fractures.

D, Post-vertebroplasty sagittal view reformatted CT scan shows cement leakage (arrow) into the L1–L2 disk. Of note, leakage of cement into the T11–T12 disk also occurred. However, T11 was treated with vertebroplasty at the same time as T12 and T11 therefore could not be evaluated for a possible new fracture.
