Primary iliac bone tuberculosis: a case report.

Tuberculosis (TB) remains one of the world's leading causes of morbidity and mortality. It occurs in both pulmonary and extra-pulmonary forms. Primary iliac bone TB remains a rare clinical entity, even in endemic areas. The diagnosis of the disease can be challenging due to its similarity to other bone diseases. We report a rare case of primary iliac bone TB in a 63-year-old patient who was on peritoneal dialysis and had a medical history of hypertension and type II diabetes, which was complicated by diabetic retinopathy and diabetic kidney disease. Magnetic resonance imaging revealed osteomyelitis in the iliac bone, while real-time polymerase chain reaction using the GeneXpert system on a gluteal collection sample confirmed the diagnosis of TB. The integration of advanced molecular tools, such as GeneXpert, represents significant progress, enabling rapid and accurate diagnosis of TB and facilitating early initiation of treatment.
