纤维瘤、卵泡膜细胞瘤和纤维卵泡膜细胞瘤统指一系列非癌性性索间质肿瘤，其特征是存在成纤维细胞基质细胞和/或类似黄素化卵泡膜细胞的细胞。在本报告中，我们介绍了一个 52 年的案例研究- 通过 MRI 发现这种罕见肿瘤的老年患者，强调了与之相关的独特诊断和治疗注意事项。卵巢纤维卵泡膜瘤肿瘤并不常见，占所有卵巢肿瘤的不到 4%。尽管它们可能出现在任何年龄，但在老年人和绝经后个体中更常见。诊断取决于临床和临床旁数据，但明确的确认主要通过解剖病理学检查来实现。对于年轻患者，通常倾向于保守手术，而围绝经期或绝经后个体可能会接受根治性治疗。卵巢纤维膜瘤虽然罕见，但通常是良性肿瘤，常见于老年患者。诊断主要依靠组织学检查。幸运的是，这些肿瘤的预后通常良好。版权所有 © 2024 作者。由爱思唯尔有限公司出版。保留所有权利。

Fibroma, thecoma, and fibrothecoma collectively denote a range of non-cancerous sex cord-stromal tumors distinguished by the presence of fibroblastic stromal cells and/or cells resembling luteinized theca cells.In this report, we present a case study of a 52-year-old patient in whom this uncommon tumor was identified via MRI, highlighting the distinctive diagnostic and treatment considerations associated with it.Ovarian fibrothecoma tumors are infrequent, constituting less than 4 % of all ovarian tumors. Although they may manifest at any age, they are more commonly observed in elderly and post-menopausal individuals. Diagnosis hinges on clinical and paraclinical data, yet definitive confirmation is predominantly achieved through anatomopathological examination. For younger patients, conservative surgery is usually favored, whereas peri- or post-menopausal individuals may undergo radical treatment.Ovarian Fibrothecoma, though rare, are typically benign tumors frequently found in older patients. Diagnosis primarily relies on histological examination. Fortunately, the prognosis for these tumors is generally favorable.Copyright © 2024 The Authors. Published by Elsevier Ltd..
