Hidatidosis cervical: compromiso de tiroides y glándula submaxilar en dos casos / Neck located hydatid cysts: report of 2 cases

Neck located hydatid cysts are of rare occurrence. We report two patients with such condition. A 66 years old male with a slowly progressive painless 4 cm nodule located in the right thyroid. It did not concentrate 131I and a fine needle aspiration cytology was informed as an acute thyroiditis. A 5 years old boy presented with a 5 cm painless right submaxillary cyst. Ultrasound examination showed that it was unilocular, and fine needle aspiration biopsy disclosed unspecific findings. In both cases surgical findings and the pathological study showed hydatid cysts. Both patients had normal chest x ray and abdominal ultrasound examinations. They had an uneventful postoperative evolution. Echinococcosis must be considered in the differential diagnosis of cervical cysts in endemic area
