OBJECTIVES: The aim of this study was performed to investigate the salivary gland SPECT/CT of parotid glands in patients with lymphoepithelial sialadenitis including preliminary study on clinical and pathological features.
METHODS: The study was performed in 5 patients with lymphoepithelial sialadenitis who underwent salivary gland SPECT/CT. Correlation between maximum standardized uptake value (SUV) at ratio of pre- to post-stimulation and clinicopathological parameters in lymphoepithelial sialadenitis were performed by Pearson correlation coefficient.
RESULTS: The maximum SUV of 10 parotid glands in 5 patients with lymphoepithelial sialadenitis using salivary gland SPECT/CT was 23.8 ± 16.9 at pre-stimulation, 10.5 ± 5.1 at post-stimulation, and 2.06 ± 0.66 at ratio of pre- to post-stimulation. Furthermore, the maximum SUV at ratio of pre- to post-stimulation was significantly correlated with Saxon test score (r = 0.637, p = 0.048).
CONCLUSION: The salivary gland SPECT/CT can be useful in clinical practice for the quantitative management of parotids in patients with lymphoepithelial sialadenitis.
