Disease resolved in 63.2% after 6 weeks of antibiotics. Mortality was 21.1%. Age, diabetic control, duration of diagnostic delay, cranial nerve involvement, and inflammatory markers were not found to predict prognosis. Erythrocyte sedimentation rate and C\u2010reactive protein levels correlated with disease activity and can be used to monitor progress. Clival involvement was associated with persistent disease (<jats:italic>P<\/jats:italic> =. 002).
