摘要
目的分析垂体细胞瘤的MRI影像学特征。方法回顾性分析7例经手术病理证实的垂体细胞瘤患者的临床和影像学资料。结果临床上主要表现为头痛和视力障碍。垂体细胞瘤大多呈类圆形或椭圆形,边界清晰。3例位于鞍上,2例位于鞍区,2例为鞍上和鞍区混合性肿块。与脑白质相比,垂体细胞瘤T1WI多呈等信号,T2WI多呈等或稍高信号,增强扫描病灶明显强化。结论垂体细胞瘤的MRI表现具有一定的特征性;MRI多方位成像可对肿瘤明确定位,并有助于定性诊断。
Objective To analyze the characteristics on magnetic resonance imaging（MRI） in 7 cases with pituicytoma. Methods Clinical data and MRI findings of 7 patients with pituicytomas confirmed pathologically were analyzed retrospectively. Results The headache and poor vision were the most clinical manifestations. Of 7 cases, 3 pituicytoma located in the suprasellar,2 pituicytomas in the sellar and suprasellar and 2 pituicytoma in the sellar. The pituicytomas were mostly round or oval, sharp defined. Compared to cerebral white matter, the pituicytomas were generally isointense to gray matter on T1-weighted images and isointense to slightly hyperintense on T2-weighted images, which were enhanced intensely. Conclusion The pituicytomas have some characteristics on MRI. Multidimensional MRI is helpful in locating the tumor and differentiating benign from malignant.
