case_images: Preoperative magnetic resonance imaging of the patient: (a) Axial T2 view, (b) sagittal T2 view, (c) sagittal T1 view, (d) myelogram, and (e) short tau inversion recovery (STIR) view showed expansile and heterogeneous cystic bone lesion with fluid signal intensity (T1: Hypointense with T2 and STIR hyperintense) and thin internal septation and cord compression at the T6 vertebra.

case_images: An MRI scan revealed a cystic tumor with internal septations involving the spinous process, lamina, pedicle, and body of the T6 vertebra [Figure 1].
case_images: Follow-up magnetic resonance imaging study of the patient, ten days after the first surgery: (a) T1 with contrast axial view, (b) T2 axial view, (c) myelogram, (d) T1 with contrast sagittal view, (e) T2 sagittal view, and (f) T1 sagittal view showed an expansile and heterogeneous cystic bone lesion with fluid signal intensity (T1: Hypointense with T2 and short tau inversion recovery (STIR) hyperintense) and thin internal septation and cord compression at the T6 vertebra. As shown above, laminectomy and cord decompression were performed. Tumor remnants at the pedicle and posterior parts of the body can be seen. The spinal cord is decompressed relatively.

case_images: A follow-up MRI showed minimal lesion residue with slight thecal sac compression [Figure 2].
case_images: Magnetic resonance imaging study of the patient before the second surgery (21 days after the first surgery): (a) T2 axial view, (b) T2 sagittal view, (c) T1 sagittal view, (d) sagittal short-tau inversion recovery (STIR) view, and (e) myelogram showed an expansile and heterogeneous cystic bone lesion with fluid signal intensity (T1: Hypointense with T2 and STIR Hyperintense) and thin internal septation and fluid-fluid level and significant cord compression at the T6 vertebra. As seen above, the tumor remnant grew rapidly, leading to cord compression.

case_images: MRI revealed rapid tumor growth and significant spinal cord compression [Figure 3].
case_images: Postoperative plain radiography of the second surgery (a) Lateral view and (b) AP view demonstrated T6 posterior vertebral column resection with posterior T3-T9 pedicle screw fixation.
