Magnetic resonance imaging findings in spinal tuberculosis: Comparison of HIV positive and negative patients

Indian Journal of Orthopaedics, 03/16/2012

There is no difference in the incidence of cord signal or presence of non–contiguous lesions. HIV positive patients show a trend to a greater epidural abscess volume. This difference may be explained by the reduced autoimmune response of the type 4 hypersensitivity reaction caused by the HIV infection.
