An Intramedullary Tuberculous Abscess of the Conus in a 5-Year-Old Child Presenting with Urinary Dysfunction

To the best of the authors' knowledge, an intramedullary conus tuberculous abscess in a young child presenting with urinary dysfunction has never been reported. Perhaps hematogenous spread of M. tuberculosis within the conus, encapsulated proliferation and caseating necrosis (owing to delayed-type hypersensitivity), and an osmotic increase in the fluid content were responsible for its genesis and for the lack of arachnoidal adhesions around the cord. Surgical decompression of the abscess established the diagnosis, increased penetrability of ATT, and decreased the biologic load of bacteria, achieving a good recovery.
