Biopsy of a vertebral lesion - tuberculosis

This 36-years old man had back pain. His MRI had shown a lesion in the L2 vertebral body. The assumption was of tuberculosis, but the findings were not pathognomic. A CT guided biopsy was advised. The CT scan shows an osteolytic lesion with sclerosis with minimal adjacent soft tissue. Instead of biopsying the soft tissue, it was felt that the best thing would be to go through the sclerotic bone into the osteolytic lesion - this was done and the biopsy material obtained was proven to be tuberculosis.
