Lipomatous meningiomas are extremely rare subtypes of benign meningiomas and are classified as metaplastic meningioma in the World Health Organization classification. We present a 77-year-old man presented with the history of a gradually intensifying headache for the last 3 months. A right frontoparietal mass was detected on his cranial magnetic resonance imaging. The patient was operated on via a right frontoparietal craniotomy, and histopathological diagnosis was lipomatous meningioma. Distinctive characteristics of lipomatous meningiomas were discussed with special emphasis to importance of immunohistochemical examinations, particularly for its differentiation from the tumors showing similar histology though having more aggressive character.
脂肪性脑膜瘤是良性脑膜瘤中极为罕见的亚型，在世界卫生组织分类中被归类为化生型脑膜瘤。我们报告一例77岁男性，在过去3个月中有逐渐加重的头痛病史。其头颅磁共振成像检查发现右侧额顶部有一肿块。该患者接受了右侧额顶部开颅手术，组织病理学诊断为脂肪性脑膜瘤。本文讨论了脂肪性脑膜瘤的独特特征，特别强调了免疫组化检查的重要性，尤其是在鉴别诊断方面，即与组织学表现相似但具有更强侵袭性的肿瘤相鉴别。
