Abstract

Although salivary gland tissues in the posterior pituitary are occasionally observed in microscopic examination at autopsy, these tissues are considered clinically silent. Only three examples of symptomatic salivary tissues in the pituitary have been previously reported. We report a case of symptomatic salivary gland rest within the pituitary gland. A 19-year-old woman complained of headache for 2 months, and dizziness, nausea, blurred vision for 1 week. Magnetic resonance imaging revealed a 1.8 cm-sized mass in sella turcica with hyperintensity on T1-weighted images. Basal hormone levels and combined pituitary stimulation test were normal. The trans-sphenoidal approach of tumor removal was performed and a pathological examination confirmed salivary gland rest without any evidence of a pituitary adenoma. The symptoms had disappeared, except for post-operative diabetes insipidus.

Keywords: salivary gland rest, pituitary gland

Figures and Tables

Fig. 1
MRI demonstrated about 1.8 cm mass in the pituitary gland (A, B. T1 weighted images, C, D. post-contrast T1 weighted images). The lesion was hyper-intense on T1 weighted images, and showed enhancement on post-contrast T1 weighted images.
