[Bronchogenic cyst of the tongue: a very rare localization].

Bronchogenic cysts are extremely rare in the tongue. We explain this localization by abnormal detachment of accessory lung buds from the primitive foregut. MR is the best imaging modality to evaluate lesions of tongue. Enucleation is the best treatment option. We present and discuss the case of a six month old infant presenting with a congenital tongue mass. This mass was a bronchogenic cyst.
