Hydatid cysts may occur in any area of the body, but usually localize to the liver and the lungs. Primary localization in muscle isn’t common, accounting for 2-3 % of all sites. We presented a patient with hydatid cyst, diagnosed by ultrasonography and computed tomography, and the cyst was located in the paravertebral muscle of the patient. Surgical and medical treatment combination.The intact intramuscular cyst was completely excised. Postoperatively, the patient began receiving albendazol 400 mg twice daily, for 6 months. At two years postoperatively, a clinical and radiological examination yielded no evidence of recurrence.
