Objective: Our aim is to describe the epidemiological, clinical and paraclinical features of intrathyroidal parathyroid cysts (PCs).

Materiel and Methods : We report 2 cases of intrathyroidal PC treated in our ENT department.

Results : We report 2 cases of non-functioning intrathyroidal PCs: 2 women (22 and 45 years old). They were referred to our department for anterior neck mass lasting for an average of 13 months. They had no compressive symptoms. Physical exam showed a soft, non-tender and well-limited anterior neck mass moving on swallowing. The mean size of the swellings was 3,5 cm. Ultrasonography of the neck revealed a right cystic thyroid nodule in the 2 cases. The mean size of the nodules was 42 mm. The serum TSH level was normal in all cases. The patients underwent right lobo-isthmectomy. Intra-operative examination suggested a benign cystic thyroid nodule. Post-operative histological exam confirmed the diagnosis of intrathyroidal PC. After an average follow-up of 3 years, no recurrence was noted.

Conclusion : Parathyroid cyst is a very rare entity. Ectopic sites are more uncommon. Intrathyroidal location is an exceptional ectopic location. To the best of our knowledge, eight intrathyroidal PC cases have been reported in the literature. They are often incidentally discovered in the histological exam after surgery.
