Pyogenic sacroiliitis in a 14-year-old girl
- 88 Downloads
Pyogenic sacroiliitis (PS) is an uncommon joint infection. Clinical presentation may be misleading, since it can resemble more common conditions such as sciatica, acute abdomen or septic arthritis of the hip.
We report a 14-year-old girl with PS. She presented at another hospital with fatigue and a six-day history of progressive low back pain radiating down to the right knee. Plain X-ray examination and computed tomography (CT) scans of the spine were normal. She was discharged with analgesic therapy. As she developed high fever over 40°C, worsening pain and immobility, she was admitted to our emergency department. Although the temperature at that moment was only 37.2°C, she appeared ill. The right sacroiliac joint and buttock were tender. Internal and external rotation, extension and flexion of the hip were decreased and painful. Compression of the sacroiliac joint was very painful. Further clinical examination was normal.
