 Again seen are multiple compression fractures throughout the thoracic spine including T5, T7, T10, and T11 with evidence of cement augmentation at the T7, T10, and T11 levels. Minimal cement extravasation dorsally to the T10 vertebral body is again seen. No evidence of interval height loss, edema, or evidence of new compression fracture in the thoracic spine. Again seen is evidence of prior laminectomy and posterior fusion from T4 to T6 including placement of two cages at the T5 level. Paraspinous rods and pedicle screws are unchanged better assessed on same-day CT. Areas of solid bony bridging from T4 to T6 better assessed on same-day CT.Mild exaggeration of the thoracic kyphosis with apex at the T5 level is again noted. Osseous retropulsion at the T5 level is again noted into the anterior epidural space with the spinal canal surgically decompressed posteriorly at this level. Unchanged mild deformity of the ventral cord at the T5 level without cord signal abnormality. Remainder of the thoracic spine demonstrates mild multilevel degenerative changes without significant spinal canal stenosis. There is moderate T8-T9 and right T10-T11 neural foraminal stenosis and to a milder degree at additional levels. Prominent facet arthropathy at the T10-T11 level again seen with mild effacement of the posterior lateral thecal sac.Bone marrow signal abnormality at the T5 compression fracture is not well assessed due to the hardware. There is no however appreciable change or new soft tissue mass to suggest tumor growth. No evidence of epidural tumor or neoplastic involvement at additional levels. LUMBAR SPINE
1. Multiple compression fractures involving the thoracic and lumbar spine as described above are again seen. No evidence of interval height loss, new bone marrow edema, or new compression fracture since 10/15/2013.2. No suspicious enhancement within the thoracic or lumbar spine to definitively suggest neoplasm. Heterogeneous bone marrow including areas of mild enhancement in the pelvis are not significantly changed and compatible with history of lymphoma. Suggest correlation with PET for any evidence of active disease.3. Postoperative changes of fusion from T4 to T6 again seen and better assessed on CT thoracic spine from same day.4. Unchanged effacement of the ventral epidural space and mild deformity of the ventral cord at the T5 level related to osseous retropulsion. Spinal canal is posteriorly decompressed at this level. No new mass effect or evidence of cord signal abnormality.
