Sacrolitis in the Post-Operative Period : A Rare Complication In a Young Female Following Ectopic Pregnancy Surgery : A Case Report

Sacroiliitis, the inflammation of one or both sacroiliac joints, often leads to lower back pain and leg discomfort. Its diagnosis is complicated due to the SI joint's complex anatomy and function. A 20-year-old female patient with a history of laparoscopic surgery for ectopic pregnancy and a previous cesarean delivery presented with bilateral lower limb weakness, sacral pain, left leg parasthesias, and constipation. MRI revealed increased STIR signal intensity in the left sacroiliac joint, confirming left-sided sacroiliitis. The patient was managed conservatively with a regimen of corticosteroids, non-steroidal anti-inflammatory drugs, and other supportive medications. This case highlights the importance of considering sacroiliitis in patients with post-surgical or pregnancy-related lower back pain and the role of imaging in diagnosis.
