A review of the pertinent literature regarding glial cysts of the pineal region is presented. Various pathogenic factors have been advocated such as the physiological involution of the pineal gland, a sequestration of the embryonic cavum pineale or the degenerative evolution of glial inclusions within the pineal gland. The pathological description is classical with three layers: an external fibrous capsule, an intermediate layer of pineal tissue and an internal glial wall. Imaging of these lesions is typical, namely the thin rim of peripheral contrast enhancement and the presence of calcifications. These cysts are more frequent in women in their third decade of life. They are almost always latent and their fortuitous disclosure at NMR examinations is common. Some of them will nevertheless cause intracranial hypertension due to hydrocephalus and hemorrhage. Those symptomatic cysts should be treated. Surgical excision has been the method of choice and the results are good. More recently a mere stereotactic needle aspiration has been performed with satisfactory long-term results.
本文对松果体区胶质囊肿的相关文献进行了综述。人们提出了各种致病因素，如松果体的生理性退化、胚胎松果体腔的隔离或松果体内胶质包涵体的退行性演变。病理描述具有典型的三层结构：外部纤维囊、中间的松果体组织层和内部胶质壁。这些病变的影像学表现具有特征性，即周边对比增强的薄环和钙化的存在。这些囊肿在30岁左右的女性中更为常见。它们几乎总是潜伏性的，在核磁共振检查中偶然发现很常见。然而，其中一些囊肿会因脑积水和出血而导致颅内高压。那些有症状的囊肿应该接受治疗。手术切除一直是首选方法，效果良好。最近，单纯的立体定向针吸术也取得了令人满意的长期效果。
