Streptococcus salivarius meningitis and sphenoid sinus mucocele. Case report and literature review.

We report a case of meningitis caused by Streptococcus salivarius in a 49-year-old woman with a previously undiagnosed cerebrospinal fluid fistula due to a sphenoid mucocele. We reviewed the literature concerning meningitis caused by this uncommon organism and to the best of our knowledge this is the first case of S. salivarius meningitis associated with sphenoid mucocele.

STIR sequence in infectious sacroiliitis in three patients.

Magnetic resonance imaging (MRI) provides the most detailed evaluation of the sacroiliac (SI) joint and surrounding soft tissue. Therefore, this technique represents the most sensitive and specific method in early diagnosis of infectious sacroiliitis. Among three patients diagnosed as having infectious sacroiliitis in our hospital, the short tau inversion recovery sequence (STIR) was found to be more effective than the T1 contrast-enhanced sequence, particularly in delineating all findings of the SI joint inflammation and allowing for the early detection of septic sacroiliitis.
