In a simplistic and succinct way, Liliequist membrane may be understood as a projection formed by an arachnoid membrane extending from the dorsum sellae to the mammillary bodies. In spite of being well known to neurosurgeons, many radiologists neither know this anatomical structure nor give importance to its study. The imaging evaluation of this membrane is feasible and may be interesting for a better preoperative planning; postoperative evaluation of third ventriculostomies; and understanding of suprasellar arachnoid cysts and perimesencephalic hemorrhage. The present article illustrates the anatomy of the membrane, with emphasis on imaging findings, besides describing its possible clinical and surgical implications.
简单扼要地说， Liliequist膜可理解为从鞍背延伸至乳头体的蛛网膜形成的一个投影。尽管神经外科医生对其熟知，但许多放射科医生既不了解这种解剖结构，也不重视对它的研究。对该膜进行影像学评估是可行的，对于更好地进行术前规划、第三脑室造瘘术后评估以及理解鞍上蛛网膜囊肿和中脑周围出血可能会很有意义。本文除了描述该膜可能的临床和手术意义外，还重点阐述了其解剖结构及影像学表现。
