Abstract

Thoracolumbar paraspinal myonecrosis can be developed with various etiologies. It can induce compartment syndrome of spinal muscles and cause elevated pressure on back muscles, resulting in severe back pain. Thoracolumbar paraspinal myonecrosis is a very rare disease. There are only a few studies about paraspinal myonecrosis. Here we report a case of a spontaneous thoracolumbar paraspinal myonecrosis in a patient who had asymptomatic abdominal aortic dissection. Through this case, etiologies, clinical features, radiologic findings, and treatment options for thoracolumbar paraspinal myonecrosis are discussed.
