Three additional cases of thorotrast retention within a paranasal sinus are added to the 7 previously reported in the literature. Carcinoma of the antrum developed in 2 of these cases approximately 10 years and 15 years after instillation, while the third case exhibited benign polypoid changes 13 years after instillation. Its recognition within a sinus cavity is important, not merely from the standpoint of the removal of a foreign body, but from the proclivity of this substance to produce necrosis and malignant change in tissue with which it remains in contact.
