Introduction: The hydatid cyst location in the thyroid gland is very rarely mentioned with an incidence varying between 0% and 3.4%due to the absence of specific clinical elements and the exceptional nature of this location. The aim of our work to study the epidemiological, clinical and therapeutic aspects of hydatid cyst of the thyroid gland. We report five cases of hydatid cyst of thyroid gland carried out in our ENT department.

Results: The average age of the patients was 40 years old with a range of 26 to 51 years. All patients were living in a rural area. Only one patient had undergone previous surgery for hydatid cyst disease. The patients consulted with firm basicervical swelling in 4 cases and renitent in one case. No sign of compression was associated (no dyspnea or dysphonia if dysphagia). Cervical ultrasound showed a multinodular goiter with multiple cystic nodules in 3 cases and a solitary solidocystic nodule in 2 cases. The treatment was loboisthmectomy in 2 cases and total thyroidectomy in 3 cases. The diagnosis was confirmed post operatively by pathology. There was no recurrence after an average follow-up of 3 years

Conclusion: The location of the hydatid cyst in the thyroid gland is rare, even in countries with high endemicity. The clinical symptoms depend on the location and size of the cyst. Positive diagnosis can be difficult preoperatively. The treatment is exclusively surgical, removing the cyst without breaking it.
