By this case, it is emphasized that spinal hydatid cyst should come to mind in the differential diagnosis of spinal cord compression, and the importance of prevention, early diagnosis, and treatment is highlighted because of high mortality and morbidity.

Spinal hydatid disease is an infestation characterized by multivesicular diffuse infiltration of the cancellous bone, including corpus vertebrae, pedicles, and the lamina. This is a rare condition leading to severe neurological problems. In the spinal area, the most commonly involved part is the thoracic region. Diagnosis is difficult and frequently delayed until signs and symptoms of spinal cord and nerve compression develop. There are no characteristic signs and symptoms. Most common signs are low back pain, radicular pain, paraparesis or paraplegia, sensation disorders, and bladder/intestine dysfunction. Magnetic resonance imaging (MRI) is the most sensitive diagnostic method. In the treatment of spinal hydatid cyst, surgery is still accepted as the "gold standard". Antihelmintic agents and benzimidazole derivatives can also be combined with surgical treatment, particularly for preventing recurrences. After review of the related literature, it is emphasized that physicians should be careful in the differential diagnosis of patients applying with spinal pain, radicular pain, progressive myelopathy or spinal cord compression syndrome. Because of high mortality and morbidity; importance of early diagnosis and treatment is highlighted along with emphasizing eradication of disease.
