Background: Intramedullary spinal cord abscess (ISCA) is an extremely rare disease, which has had fewer than 250 reported cases since its initial description in 1830. The condition is limited to level V evidence, limiting the ability for surgeons to characterize and treat it.
Objective: To report the cases of 2 patients with ISCA and their surgical management: a 59-year-old woman who presented with progressive right hemiparesis and a 69-old man who presented with acute gait instability and significant bilateral shoulder pain. In addition, to report findings from a systematic literature review and associated logistic regression analysis.
Methods: A MEDLINE and Embase search was conducted using the keywords "intramedullary," "spinal cord," "abscess," and "tuberculoma" and the results were screened for case reports. A logistic regression model was fit 100 times on data to retrieve predictor odds ratios.
Results: Two hundred case reports of ISCA were identified between 1965 and 2022. Logistic regression determined that the only variables of significance were age (P < 0.01) and antibiotics (P < 0.05).
Conclusions: Treatment of ISCAs has significantly improved over the years. However, ISCAs are still poorly understood. Our recommendations can be used to guide diagnosis and treatment.
