Arachnoiditis ossificans is a rare disorder characterized by the development of calcifications of the arachnoid membrane of the thoracic and lumbar spines. It is an extremely rare cause of spinal canal stenosis and consequent neurological compromise, and its origins and optimal management remain unclear. We review of the literature that illustrates the challenges of diagnosis and treatment of arachnoiditis ossificans. A patient with arachnoiditis ossificans is discussed to illustrate the presentation, treatment, and prognosis of the disease.
