title: Pyogenic sacroiliitis. Diagnosis and significance.
abstract: Two patients are described with unilateral pyogenic sacroiliitis, 1 complicating intravenous heroin addiction and the other complicating a septic skin lesion. The need for diagnostic alertness in the early recognition of this uncommon condition is illustrated and the apparent lack of relationship of pyogenic sacroiliitis to idiopathic ankylosing spondylitis is discussed.
