Failure of washout following gustatory stimulation in Warthin's tumour.
Scintigraphically, Warthin's tumour usually demonstrates increased tracer uptake compared to normal adjacent salivary tissue. A case is presented in which tumour uptake is no greater than the normal adjacent gland. Gustatory stimulation results in failure of tumour tracer washout, and this finding rather than 'hot' salivary mass is the sine qua non of the scintigraphic diagnosis of Warthin's tumour.
