Facet joints are the important articular pillars of spine. Several pathologies can occur in and around facet joint, including extra ossicles, traumatic dislocation, osteoarthritis, synovial cyst, axial spondyloarthritis, rheumatoid arthritis, calcium pyrophosphate deposition disease, septic malignant benign neoplasms. Imaging is mainstay to detect characterize these diseases. In this review, we...
