We report a case of pituicytoma, a rare primary tumor of the neurohypophysis. A 64-year-old man presented with progressive visual complaints, bitemporal hemianopsia, and headache. Imaging studies revealed distinctive features of a mass lesion that thickened the pituitary stalk with a bilobed protrusion extending into the hypothalamus. Angiography demonstrated tumor vascular supply from the superior hypophyseal arteries representing the diencephalic branches of the internal carotid arteries. We discuss the imaging and pathology of this unusual tumor.
我们报告一例垂体细胞瘤，这是一种罕见的神经垂体原发性肿瘤。一名64岁男性出现进行性视力问题、双颞侧偏盲和头痛。影像学检查显示有一肿块病变的独特特征，该病变使垂体柄增粗，并有双叶状突出延伸至下丘脑。血管造影显示肿瘤血供来自垂体上动脉，这些动脉代表颈内动脉的间脑分支。我们讨论了这种不寻常肿瘤的影像学和病理学表现。
