A 54-year-old woman presented with an expansive mass in the anterior cervical region (front of the neck) with abscess. Laboratory tests and thyroid profile proved normal. Surgical exploration revealed a hydatid cyst in the left lobe of the thyroid gland with parasitic metastasis of the left lateral cervical lymph node chain. Postoperative examination of the nodule showed it to be a solitary primary thyroid hydatid cyst.
