Unilateral Septic Sacro-iliitis Importance of the Anterior View of the Bone Scan

Abstract
Two cases of unilateral septic sacro-iliitis are reported. Importance of the anterior view of sacroiliac joints on the radionuclide bone scan is stressed. Limitation of the posterior view in evaluation of sacroiliac joints may lead to misdiagnosis and false-negative results in unilateral sacro-illiac disease.
