Ectopic salivary gland tissue in sellar turcica is frequently observed in microscopic examination at autopsy. This tissue is considered clinically silent. Only 2 symptomatic cases have been previously reported. Here we report a 28-year-old woman presenting with galactorrhea and hyperprolactinemia. Magnetic resonance imaging revealed a 6 x 5-mm nodule in the posterior aspect of the pituitary gland. This nodule showed isointensity on T1- and T2-weighted images and less enhancement on post-contrast T1-weighted images. Transsphenoidal exploration revealed a cystic lesion within the pituitary gland, which consisted of a grayish gelatinous content. The pathologic examination confirmed the diagnosis of salivary gland rest.
蝶鞍内异位唾液腺组织在尸检显微镜检查中经常被观察到。这种组织在临床上被认为是无症状的。此前仅报道过2例有症状的病例。在此,我们报告一名28岁女性,表现为溢乳和高催乳素血症。磁共振成像显示垂体后部有一个6×5毫米的结节。该结节在T1加权和T2加权图像上呈等信号,在增强后T1加权图像上强化较少。经蝶窦探查发现垂体内部有一个囊性病变,其内容物为灰白色胶冻状。病理检查证实为唾液腺残余。
