摘要垂体神经内分泌肿瘤(PitNETs)是起源于腺垂体的良性肿瘤，可以破坏周围硬脑膜而侵入毗邻结构。作为PitNETs侵袭性的重要生物学表现以及PitNETs病理分型的重要依据，硬脑膜侵袭成为目前PitNETs侵袭性研究的重点。本文现综合近年来国内外开展的PitNETs硬脑膜侵袭相关研究，从解剖结构、影像表现及组织病理方面对研究进展情况进行综述，归纳硬脑膜侵袭在PitNETs侵袭性研究中的最新成果。

abstractsPituitary neuroendocrine tumors (PitNETs) are benign tumors arising from the adenohypophysis and can destroy the surrounding dura mater and invade adjacent structures. Dural invasion, as an important biological manifestation of PitNETs invasiveness and an important basis for PitNETs pathological classification, has become an important part in invasive study of PitNETs. In this paper, the research progress of dural invasion of PitNETs carried out at home and abroad in recent years has been reviewed from aspects of anatomical structure, imaging manifestations and histopathology, and the latest results of dural invasion in PitNETs invasion are summarized.
