Abstract

Bindal M, Krabak B. Acute bacterial sacroiliitis in an adult: a case report and review of the literature.

Bacterial septic sacroiliitis is an uncommon diagnosis that occurs most frequently in children and young adults. Nonspecific physical examination findings often make it difficult to diagnose the condition, thus delaying appropriate treatment. We review the case of middle-aged woman with sacroiliac joint (SIJ) pain after a torsional injury. Radiographic films showed the pelvis and left lower extremity to be normal. Despite anti-inflammatory medications, analgesics, a corticosteroid injection, and physical therapy, her pain persisted. Laboratory data showed an elevated erythrocyte sedimentation rate and C-reactive protein; otherwise, tests were normal, including negative blood cultures. Magnetic resonance imaging (MRI) revealed a left posteroinferior SIJ effusion and computed tomography (CT) showed an effusion and irregularity in the left SIJ. An SIJ biopsy revealed inflammation suggestive of osteomyelitis. After a course of intravenous antibiotics, the symptoms completely resolved, thus supporting our diagnosis of bacterial sacroiliitis. Repeat MRI and CT confirmed the complete resolution of the sacroiliitis.

Case Description

A 40-year-old woman without significant medical history presented to our clinic with a 2-week history of pain in the left gluteal region. She said her pain began after she lurched forward while carrying her luggage at the airport. The pain was sharp and progressed over the next several hours while she was on the aircraft, prompting her to seek an evaluation in the emergency department. Radiographs showed no abnormalities in the pelvis and hip. The patient was treated for a muscle strain and was

Discussion

Bacterial septic sacroiliitis is more typically seen in children and young adults than in middle-aged or elderly persons.5 In adults, there is often a history of intravenous drug use, skin and respiratory infections, or genitourinary tract infections. It is thought that the majority of septic sacroiliitis cases occur through hematogenous seeding from a preexisting infection from a distant site.2, 5 Others have suggested it is the result of local spreading of infection from a spinal or pelvic

Conclusions

Infectious SIJ disease can be difficult to diagnose, given the nonspecific symptoms and physical examination findings. Clinicians should be aware of the diagnosis, however, even in the acute setting or in unilateral cases. With appropriate laboratory and imaging workup, the appropriate treatment can be initiated without delay and without any long-term complications. As was true for our patient, the proper identification of bacterial septic sacroiliitis frequently leads to a positive outcome.

    In a review of 15 patients in the pregnant/postpartum period by Imagama et al. only 3 cases were managed with open drainage with a further single patient requiring a hysterectomy and oophorectomy [8]. Septic sacroiliitis remains an important differential given immunosuppression of pregnancy and hypothesised hormonal effects on joint laxity; albeit limited, literature certainly suggests pregnancy may be an independent risk factor for its development [6–8,12]. The case presented here represents another rare presentation of septic sacroiliitis with disseminated infection and haematogenous spread adding to a small but significant number of patients making septic sacroiliitis a differential to always consider in the post-partum patient presenting with non-resolving, severe pelvic pain.

    It is more typically seen in children and young adults than in the middle-aged or older adults. Diagnosis is often difficult due to the nonspecific clinical presentation [8]. Infection of the SI joint may occur via hematogenous seeding or from local extension of an infectious process.

    2014, Egyptian Rheumatologist
    Citation Excerpt :

    Infectious sacroiliitis is rare, involving between 1% and 2% of septic arthritis cases, which is probably due to the poor vascularization of this joint resulting in a low risk of infection via the haematogenous route [1,2]. Most observations are based on single case reports and review of the literature [3–8], small case series [9,10] or multicentre studies [11]. The diagnosis of osteoarticular infection is difficult in these anatomical sites and may be delayed due to the poor specificity of clinical signs and symptoms [1,12–14].
