Perinatal Sacroiliitis Diagnostic Challenges: A Case Report
Background: Lumbo-pelvic (LPP) pain is common and non specific problem during pregnancy and post partum. Despite the fact that perinatal pyogenic sacroiliitis (PSI) during this period is rare, it should be considered as a vital differential diagnosis in women who have debilitating lower back and pelvic girdle pain. Case: A 34 years old primigravida presented to the emergency department with extreme right sided lower back pain radiating to the right gluteal region and down to the back of the right thigh. This pain began twelve days prior to her presentation and eventually worsened to the point that she couldn't stand or walk. Her vital signs were within normal limits, and she was febrile. Apart from a slight widening of the symphysis pubis, her pelvic and lumbo-sacral plain x-rays revealed no important findings. With the clinical impression of right LPP, the patient was admitted for pain management and further inquiries. Conclusion: Despite the fact that lower back and pelvic girdle pain are normal throughout pregnancy and the postpartum period, perinatal PSI is uncommon. It's a tough diagnosis to make because the symptoms and signs aren't clear, and the tests aren't definitive. When pathognomonic clinical and radiologic signs indicate an infectious process and isolation of pathogenic bacteria is not possible, medical management with empirical antibiotics should not be delayed.
