Increasing numbers of active tuberculosis in Germany were recorded in the last years. Thus, also extrapulmonary manifestations of tuberculosis gain clinical significance as differential diagnoses, especially when a metastatic tumor disease is suspected. We report the case of a 77-year-old male patient who presented with unilateral leg pain and B symptoms. Further investigations revealed an osteolytic mass in the sacrum as well as CT-morphological findings consistent with metastatic gastric cancer. However, transgastric biopsies showed necrotising granuloma with giant cells leading to molecular and cultural detection of Mycobacterium tuberculosis instead of suspected neoplastic tissue. A nine-month treatment regimen for suspected disseminated tuberculosis with bone involvement was initiated according to national guidelines. Clinical and radiological follow up examinations after treatment completion showed complete remission.      «
