Unilateral Gallium-67 Uptake in Submandibular Salivary Gland Following Sialography

Intravenous administration of contrast media and oral ingestion of iodide have been suggested as possible causes for sialadenites, which are thus sometimes referred to as “iodine mumps.” Ga-67 uptake has not been described in such cases. However, uptake has been reported in the lungs and lymph nodes following lymphangiography, probably resulting from the inflammatory reaction to the contrast material in the pulmonary parenchyma and the lymph nodes. A case is presented with unilateral Ga-67 uptake in a submandibular salivary gland five days following sialography. It is therefore recommended to perform Ga-67 imaging in the evaluation of salivary gland pathology prior to sialography in order to avoid false-positive increased Ga-67 uptake following the procedure.
