THE ROLE OF ULTRASOUND AND OESOPHAGOGRAPHY IN THE MANAGEMENT OF ACUTESUPPORTIVE THYROIDITIS IN CHILDREN ASSOCIATED WITH CONGENITAL PYRIFORM FOSSA SINUS

The thyroid is remarkably resistant to infection. Hence, when an infec tion does occur, the presence of a pyriform fossa sinus must be consid ered, particularly if it is recurrent and left sided. The aim of this paper is to alert radiologists to the existence, clinical presentation , and ultrasonographic and oesophagographic appearances of a pyriform fossa sinus. We present the role of ultrasound and oesophagography in five children with pyriform fossa sinus associated with suppurative th yroiditis. In four children the abnormality was on the left and on the right in one.
