Ectopic pituitary fossa thyroid tissue.
Developmental anomalies of the thyroid gland may result in ectopic glandular tissue. We report a unique case of ectopic thyroid tissue within the pituitary fossa and sphenoid sinus, associated with a lingual thyroid gland. The aetiology of this ectopic tissue is postulated to be ascent of primitive thyroid endoderm at the time of formation of Rathke's pouch.
