Fig 2.

A 69-year-old man with fever 15 days after an operation for mechanical obstruction. Sagittal T1-weighted (A) and enhancement (B) MR images show low bone marrow signal change with enhancement at T12 and the L1 body and abscess formation at the anterior epidural space of the T12-L1 level. Percutaneous biopsy was performed at the T12 lower body with a left unilateral transpedicular approach under fluoroscopic guidance, which is demonstrated on anteroposterior (C) and lateral (D) spot radiographs. Pathologic findings were consistent with infectious spondylitis. The isolated causative organism was Klebsiella pneumoniae.
