Intraparenchymal meningiomas without dural attachments are extremely rare. A 32-year-old female adult was admitted to our hospital, complaining of occasional dizziness. The patient had no neurological deficits. MRI demonstrated a lesion with mild edema located in the left cerebellar parenchyma. CT revealed calcification within the mass. Gross total resection was achieved. The histopathological examination indicated that the lesion was an atypical meningioma (WHO-II). We herein report an extremely rare case of an intraparenchymal meningioma located in the left cerebellar hemisphere. The significance of the differential diagnosis of lesions in the cerebellum should be emphasized.
无硬脑膜附着的脑实质内脑膜瘤极其罕见。一名 32 岁女性因偶发头晕来我院就诊，患者无神经功能缺损。MRI 显示病变位于左小脑实质，伴轻度水肿。CT 显示肿块内有钙化。行大体全切除。组织病理学检查提示病变为非典型脑膜瘤（WHO-II 级）。本文报道了一例极其罕见的左小脑半球脑实质内脑膜瘤。强调了小脑病变鉴别诊断的重要性。
