Pyogenic sacroiliitis is rare and difficult to diagnose because of its deep location and the absence of definitive clinical signs. Delayed diagnosis can result in complications such as abscess or sequestration formation, prolonged sepsis, and chronic joint deformity. MRI is a well-known, noninvasive imaging technique with a high sensitivity and specificity for osteomyelitis diagnosis. Here, we present the MRI findings for pyogenic sacroiliitis, 3 days after symptom onset, in an 11-year-old girl and confirm its value in early diagnosis of pediatric pyogenic sacroiliitis.
