A case of non-neoplastic pineal cyst with Parinaud's syndrome is presented. A 54-year-old woman was admitted to the department of neurosurgery. Fukui Medical School on October, 1985, complaining of the paralysis of upward gaze. A computed tomography (CT) demonstrated a low density mass in the pineal region and the mass was not enhanced after the injection of contrast agent. Metrizamide CT cisternogram delineated the mass clearly. Bilateral carotid and vertebral angiograms showed no significant findings. On November 5, an operation was performed by means of an occipital transtentorial approach. A cyst filled with clear yellowish fluid was found in the pineal region. The cyst was evacuated and its wall was subtotally resected. The histological examination revealed the cystic cavity lined by fibrous astrocytes which were surrounded by normal pineal tissue. Therefore the cyst was diagnosed as a non-neoplastic pineal cyst. The postoperative course was uneventful. The paralysis of upward gaze was gradually improved. On December 27, the patient was discharged in excellent condition. Non-neoplastic small cysts which do not cause an enlargement of the pineal body are common incidental findings at autopsy, whereas large cysts which cause symptoms due to compression of the corpora quadrigemina and the production of internal hydrocephalus are rare. In this paper, non-neoplastic pineal cyst is discussed.
本文报告一例伴有帕里诺德综合征的非肿瘤性松果体囊肿。一名54岁女性于1985年10月入住福井医科大学神经外科，主诉向上凝视麻痹。计算机断层扫描（CT）显示松果体区有一低密度肿块，注射造影剂后肿块无强化。甲泛葡胺CT脑池造影清晰地勾勒出肿块。双侧颈动脉和椎动脉血管造影未见明显异常。11月5日，采用枕下经小脑幕入路进行手术。在松果体区发现一个充满清亮淡黄色液体的囊肿。抽出囊肿内容物并对其壁进行次全切除。组织学检查显示囊肿腔内衬有纤维星形细胞，其被正常松果体组织包围。因此，该囊肿被诊断为非肿瘤性松果体囊肿。术后过程顺利。向上凝视麻痹逐渐改善。12月27日，患者状况良好出院。非肿瘤性小囊肿不引起松果体增大，是尸检时常见的偶然发现，而因压迫四叠体和产生梗阻性脑积水而引起症状的大囊肿则很少见。本文对非肿瘤性松果体囊肿进行了讨论。
