A presumed developmental variant of the dorsum sellae was found in a patient undergoing evaluation for a suspected pituitary adenoma. An initial computerized tomography (CT) scan suggested a suprasellar mass; however, high-resolution CT with reformations clearly revealed the mass to be the pituitary gland, which was deformed and displaced upward by an osseous spine projecting from the dorsum sellae. The radiographic appearance and etiology of this anomaly are discussed. Neurosurgeons and neuroradiologists should be aware of this anomaly when evaluating a patient for pituitary adenoma.
在一名因疑似垂体腺瘤接受评估的患者中发现了一种蝶鞍背的推测性发育变异。最初的计算机断层扫描（CT）显示鞍上有肿物；然而，高分辨率CT及重建图像清楚地显示该肿物为垂体，它被从蝶鞍背突出的骨性棘向上挤压变形并移位。本文讨论了这种异常的影像学表现及病因。神经外科医生和神经放射科医生在评估垂体腺瘤患者时应注意这种异常。
