|Sacroiliac joint. How to differentiate inflammatory and non inflammatory conditions|
-BME is common to both inflammatory and non inflammatory conditions.
-SIJ edema is common in asymptomatic patiens and should not be misinterpreted as inflammatory.
-It is important for radiologist to be familar with the anatomy and biomechanics of the SIJ to make the right diagnosis.
- Lesion distribution is key when dealing with small BME foci especially in young active individuals since middle and upper third is a weight bearing area and highly susceptible to mechanical damage.
-The associated findings (erosions being, by far, the most important) should also be considered, since they add specificity to the diagnosis of inflammatory sacroiliitis.
