[Accumulation of 67Ga in diseases of the large salivary glands].
In a prospective study (59 patients) the pattern of 67Ga-uptake of the large salivary glands (LSG) in the course of typical disorders of the glands was investigated. Inflammatory and granulomatous disorders revealed--dependent on their acuity--an identical pattern of Ga-uptake. Extraglandular uptake was found in some instances of tuberculosis, sarcoidosis and myoepithelial sialadenitis. Among the benign LSG tumors all cystadenolymphomas showed intensive uptake while all pleomorphic adenomas did not. In 75% of the malignant LSG tumors Ga-uptake was pathologically increased, particularly in all adenocarcinomas of the series. 67Ga scintigraphy seems to be useful in the follow-up of inflammatory and granulomatous LSG disorders and in the differential diagnosis of pleomorphic adenoma versus cystadenolymphoma. Extraglandular uptake may give valuable hints for diagnostic work-up.
