A case of axial spondyloarthritis with Paget's disease: A rare coexistence

Paget's disease (PD) is one of the most common bone disease which bone destruction and construction cycle is abnormally accelerated. Disease develops under the influence of environmental factors at genetic background. Pain is the most common complaint. Especially the waist and hip region pain might be confused with inflammatory spondyloArthritis. High serum alkaline phosphatase value is important in diagnosis. Direct X-rays, computed tomography, magnetic resonance imaging and bone scintigraphy are the most important imaging methods for suspected patients. In rare cases these two diseases can be seen together and distinguish these diseases might be difficult. In our case, referring to PD accompanying an axial spondyloArthritis patient who complained of low back pain is presented. Keywords: Alkaline phosphatase, Paget's disease, SpondyloArthritis.
