Tuberculosis is a major scourge, posing a serious public health problem in countries where it is endemic. Osteoarticular involvement accounts for 3 to 5% of all tuberculosis cases and 10 to 15% of extrapulmonary tuberculosis cases. We report a case of tibial osteitis caused by Mycobacterium tuberculosis in a 52-year-old female patient who presented to the trauma department at the Mohammed V Military Teaching Hospital with a painful swelling of the lower part of her left leg. Standard X-rays and computed tomography (CT) scans revealed bone involvement, specifically in the tibia. Additional investigations revealed pulmonary consolidation and splenic nodules. Microscopy (Ziehl-Neelsen staining), GeneXpert MTB/RIF, and histopathological examination all returned positive results for Mycobacterium tuberculosis. In an endemic context, any persistent and atypical bone lesion should raise suspicion of osteoarticular tuberculosis to enable rapid diagnosis and appropriate therapeutic management. In the absence of malignancy and other differential diagnoses, the diagnosis of skeletal tuberculosis must be considered, even in the absence of specific clinical signs.
