뇌하수체에서 발견된 증상을 유발한 이소성 타액선

뇌하수체의 이소성 타액선은 사체부검에서 종종 발견되나 증상을 유발하는 경우는 거의 없는 것으로 알려져 있다. 저자들은 두통, 오심, 현훈, 시야 흐림의 증상을 유발한 뇌하수체의 이소성 타액선 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 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. (J Kor Endocr Soc 22:436~439, 2007)
