Primary intracranial malignant fibrous histiocytoma (MFH), or myxofibrosarcoma, is an extremely rare condition, with only a few cases reported in the literature. We report a case of a dural-based myxofibrosarcoma in a previously healthy 42-year-old man that was initially presumed to be an atypical meningioma. The findings based on conventional and advanced magnetic resonance sequences, including diffusion-weighted imaging, perfusion weighted imaging and proton magnetic resonance spectroscopy, as well as histopathological aspects, are discussed.
颅内原发性恶性纤维组织细胞瘤（MFH），也称黏液纤维肉瘤，是一种极为罕见的疾病，文献中仅有少数病例报道。我们报告了一例发生于 42 岁健康男性的硬脑膜基底部黏液纤维肉瘤，最初被误诊为非典型脑膜瘤。本文将讨论其常规和先进磁共振序列（包括弥散加权成像、灌注加权成像和质子磁共振波谱）以及组织病理学特征的发现。
