We report a rare case of dorsal-lumbar spine hydatidosis. The patient is a 15-year-old girl from Chincha, Ica who, due to persistent low back pain and progressive severe paraparesis of a year of evolution, is transferred to the Maria Auxiliadora Hospital. Radiographs, computed tomography, and MRI scans showed multiple vertebral cystic images at L1 and L2 levels with severe invasion of the vertebral canal, which were reported as probable aneurysmal bone cyst. The patient underwent previous percutaneous exploration and appropriate precautions for exploratory and decompressive surgery, evidencing multiple cystic vesicles compatible with spinal hydatidosis, which was later confirmed by pathological anatomy. The clinical recovery was gradual and without cystic recurrence
Showing total recovery with last control at 4 years of the intervention.
