Zusammenfassung:Multiple causes of extrathyroidal accumulation of radioiodine have been reported. The results of an 81-year-old woman's scan showed unilateral submandibular concentration secondary to a stone obstructing Wharton's duct. The scan had been ordered to assess thyromegaly. The serendipitous combination of scintiscan findings and clinical symptoms prompted further evaluation and surgical removal of the occlusive stone. A potential false-positive interpretation was avoided because of a careful patient history as well as physical examination of the submandibular regions. Salivary duct occlusion must be added to the list of causes of extrathyroidal accumulation of radioiodine.
