Isolated posterior element Potts spine -MRI

Spinal tuberculosis is more common in the eastern countries than in the western world. Recently, there has been a renewed interest in tuberculosis in the west because of its re-emergence, especially in immunocompromised patients (e.g., HIV). The classic radiologic picture of "two vertebral disease with the destruction of the intervertebral disc" is easily recognized and readily treated, but its atypical forms are often misdiagnosed and mistreated. In tuberculosis of the posterior element of the spine, MRI is extremely useful in evaluating the extent of involvement and response to therapy of isolated tuberculosis of posterior elements. Involvement of posterior elements due to tuberculosis is not so uncommon.
