Pyogenic sacroiliac arthritis is a rare entity. The most common bacterial organism is Staphylococcus aureus. More than 50% of cases have underlying diseases, for instance, trauma, immune deficiency, psoriasis, rheumatoid arthritis, post acupuncture and pelvic inflammation etc. In healthy persons, the arthritis is connected to sport medicine, over exercise, bike riding, and running and so on. Mild and nonspecific symptoms fever, lower back pain, gluteal or hip pain are presented. Radiographic image, compute tomography (CT) and/or magnetic resonance image (MRI) with gadolinium (Gd) study are recommended. Adequate and appropriate antibiotics are the initial treatment. Surgical needle aspiration and drainage is essential in case of no response to antibiotics, and is recommended in chronic form debridement and arthrodesis.
