We present a case of a 30-year-old woman, without any notable pathological history, admitted with a slow spinal cord compression. The spinal MRI showed an extensive cystic lesion from D8 to D11 compressing the spinal cord with signs of myelopathy, costal and paraspinal soft tissues invasion, compatible with vertebral hydatidosis. The surgical procedure was a decompression by laminectomy and incomplete cystectomy with osteosynthesis. histological analysis confirmed the diagnosis of vertebral hydatidosis. vertebral location remains rare, but severe, of delayed diagnosis due to the absence of specific clinical signs, it is evoked by radiology and confirmed by histological analysis. Its prognosis remains poor with frequent recurrences. The optimal treatment is the prevention of the disease.
