Low back pain is one of the most common symptoms, having a broad range of etiologies in differential diagnosis, such as inflammatory and degenerative disorders, malignancy and infections. Herein, we present an interesting patient who initially presented with sacroiliitis and was ultimately diagnosed with stage IV lung cancer. She was initially misdiagnosed as having axial spondyloarthritis. We aim to emphasize red flags in the differential diagnosis of sacroiliitis.
