Abstract：
This article presents a case study of a rare convexity meningioma located in the frontal lobe of the right cerebellar hemisphere. Meningiomas comprise a substantial part of central nervous system neoplasms and are classified into benign, atypical, or anaplastic categories, each encompassing a variety of histological subtypes, among which the secretory meningioma is notably rare. A 77-year-old male presented with a clinical history of headache, impaired memory functions, an initial form of apathetic-abulic syndrome, and a single seizure, which were considered to be indicative of epileptic symptoms that had been present for several weeks. The imaging studies conducted showed a convexity tumor characterized by a rounded morphology and homogeneous contrast enhancement, positioned adjacent to the frontal lobe\'s cortical surface. This clinical report details the pathology of a secretory type of meningioma, which is distinguished by the atypical epithelial differentiation of meningothelial cells, resulting in hyaline fiber production. The neoplasm\'s anatomical accessibility permitted successful surgical resection. The tumor\'s position was appropriate for surgical removal, and the histological variant, along with the patient\'s favorable clinical course, is of particular scientific interest.
摘要：
本文介绍了位于右小脑半球额叶的罕见凸面脑膜瘤的案例研究。脑膜瘤是中枢神经系统肿瘤的重要组成部分，分为良性，非典型的，或间变性类别，每个都包含各种组织学亚型，其中分泌性脑膜瘤尤其罕见。一名77岁男性有头痛病史，记忆功能受损，一种最初形式的无知觉-失利综合征，和一次癫痫发作，这被认为是已经存在数周的癫痫症状的指示。进行的成像研究显示，凸状肿瘤的特征是圆形形态和均匀的对比度增强，位于额叶皮质表面附近。本临床报告详细介绍了分泌型脑膜瘤的病理，以脑膜上皮细胞的非典型上皮分化为特征，导致透明纤维的生产。肿瘤的解剖学可及性允许成功的手术切除。肿瘤的位置适合手术切除，和组织学变异，随着患者的良好临床过程，具有特殊的科学意义。
