Spinal tuberculosis is the most common form of skeletal tuberculosis. Tuberculous involvement of the lower spine is rare. Sacral tuberculosis is very rare; most reported cases in the literature are case reports. Spinal tuberculosis may present atypically: neural arch involvement, skip lesions, sacral involvement, or as extradural tuberculosis.
Diagnostic bone biopsy is an integral part of patient work-up. Patients may be infected by a variety of micro organisms, especially patients who are HIV positive or those who have AIDS.
The gold standard technique for biopsy of the sacrum is CT-guided percutaneous biopsy. The technique has a very low complication rate in experienced hands. We describe a simple, safe and fast percutaneous biopsy technique we used to obtain biopsy of the upper sacrum. The details are stated in this report.
