Abstract

Objectives: To describe the clinical presentation, spinal magnetic resonance imaging (MRI) findings and outcome of HIV-infected patients with tuberculosis (TB)-associated syringomyelia and to compare these findings between all HIV-infected and -uninfected cases published in the literature.

Methods: A retrospective observational study conducted over a 12.5-year period at a public-sector referral hospital in South Africa. HIV-infected adults with neurological TB in whom MRI confirmed a syrinx were included. We searched PubMed to identify all published syringomyelia cases.

Results: Ten patients were enrolled. Syringomyelia complicated neurological TB within four years of initial diagnosis in all patients (median: 21 months, range: 0-39) after initial diagnosis. Six patients were treated conservatively (TB treatment = 5, no treatment = 1); four improved, but only one was ambulant during follow-up. Four patients underwent syringoperitoneal shunting; three improved and one died three months later. Our literature review identified 50 additional cases (HIV-infected = 2, HIV-uninfected = 9, HIV status not documented = 39 [presumed HIV-uninfected]). Clinical and imaging findings and outcomes were similar between HIV-infected and -uninfected cases, except for time of presentation following neurological TB diagnosis, which was delayed (>4 years) in 46% of HIV-uninfected cases, compared to 8% of HIV-infected cases. Conclusions Syringomyelia is a disabling complication of neurological TB that usually presents early after neurological TB diagnosis in HIV coinfected patients.
