Disseminated tuberculosis with rare coccygeal involvement: a case report.

Abstract

Tuberculosis (TB) is a preventable and usually curable disease but remains a major health problem worldwide, particularly in developing countries. TB of the lumbosacral junction is rare and occurs in only 1-2% of all cases of spinal TB. Moreover, isolated sacrococcygeal TB is extremely rare. We present a case of a 64-year-old patient with a history of diabetes who presented with chronic back pain and cough. Physical examinations revealed a perianal fistula and left elbow joint arthritis. The patient is diagnosed with disseminated TB with coccygeal involvement. Diagnosis was achieved non-invasively using Xpert MTB/RIF, confirming Mycobacterium tuberculosis infection. The patient experienced complete resolution of symptoms following the commencement of anti-TB therapy. We highlight the importance of this case due to the rare coccygeal localization of TB in an immunocompetent patient, diagnosed through non-invasive means.
