RESUMEN
Tuberculosis is a top 10 leading cause of death worldwide. Lungs are primarily involved organs in tuberculosis. The rest of cases are extrapulmonary tuberculosis (14% reported in 2017). Extrapulmonary tuberculosis always presents with non-specific symptoms, thus at risk of delay diagnosis and management. In genitourinary tuberculosis, kidney alone and kidney with urinary bladder or ureter is affected in more than 70% of cases. The ureter and urinary bladder infections are almost always secondary to tuberculous involvement of the kidney. Bacilli haematogenic spreading is a known transmission pathway to the kidney. In this case, we diagnosed isolated urinary bladder tuberculosis caused by direct gastrointestinal tuberculosis infiltration, a rare occurrence of extrapulmonary tuberculosis. We illustrate the multiorgan involvement in tuberculosis infection including pulmonary, gastrointestinal, peritoneal and urinary bladder.
