A 61-year-old farm laborer presented to the orthopedic outpatient clinic complaining of severe back pain radiating down his right leg. He had a history of a previous episode 7 years ago when he underwent posterior spinal surgery without instrumentation. He was unsure of his previous diagnosis but had been told that the cause was "parasites." On examination, he had multiple skin nodules and a posterior midline surgical scar from T11 to L5 region. The neurologic examination proved normal with only subjective weakness in his right leg. Radiographs demonstrated T12 vertebra plana. Echinococcus Granulosum serology was negative. Magnetic resonance imaging was performed to further work-up the patient (Figures 1–4).
