Multifocal Extensive Spinal Tuberculosis Accompanying Isolated Involvement of Posterior Elements: A Case Report

ABSTRACT

STUDY DESIGN: A case report. OBJECTIVES: To report a rare case of atypical spinal tuberculosis. SUMMARY OF LITERATURE REVIEW: In spinal tuberculosis, non-contiguous multifocal involvement and isolated involvement of posterior elements of the spine have been considered atypical features. There have been a few reports of each of these atypical features but no reports have described spinal tuberculosis with both of these atypical features. MATERIALS AND METHODS: A 39-year-old man presented with back pain and progressive weakness of both lower extremities. He was diagnosed with spinal tuberculosis from the cervical to sacral spine, showing multifocal non-contiguous involvement with multiple abscesses on magnetic resonance imaging. Notably, in the thoracic spine area, isolated involvement of posterior elements was found with an epidural abscess compressing the spinal cord. He underwent a total laminectomy of the thoracic spine and multiple abscesses were drained with pigtail catheter insertions into the cervical, thoracic, and lumbar spine. RESULTS: At the 8-month follow-up, the patient's neurologic status had improved to Frankel Grade D, and the patient was able to walk with the support of a walker. At the 3-year follow-up, the patient had recovered completely without any neurologic deficit. CONCLUSIONS: Since atypical spinal tuberculosis may show various patterns, examination of the entire spine is important for early diagnosis. Treatment should be provided properly from minimally invasive procedures to open surgery depending on the extent of structural instability and neurologic deficit.
