Sacroiliitis is inflammation affecting the sacroiliac joints where the spine meets the pelvis.
Symptoms may include pain in the lower back, buttock, or back of the hip, stiffness after rest, and pain that can worsen with standing, walking, or climbing stairs.
Imaging helps when inflammatory back pain is suspected, when doctors need to look for early sacroiliac joint inflammation, or when another cause of pelvic or lower back pain needs to be excluded.
X-rays, CT, and especially MRI help detect early inflammatory change, structural damage, or other causes of pelvic pain.
Management may include rheumatology review, anti-inflammatory treatment, physiotherapy, and control of the underlying condition.
This entry explains the condition. The next step is having a radiologist interpret your specific scan, not a general definition.
