Meningiomas are benign in nature and arise from the arachnoid cells. They are mostly situated in the intracranial compartment, whereas spinal meningiomas are rare. Approximately, in 10% of cases, an extradural component is seen but an exclusively extradural meningioma is quite uncommon. However, WHO Grade II (atypical) and Grade III (anaplastic) tumors can behave aggressively. We reported a case of purely extradural psammomatous meningioma in an adult male affecting the dorsal spine although uncommon meningiomas should be included in the differential diagnosis of extradural intraspinal masses.
脑膜瘤本质上是良性的，起源于蛛网膜细胞。它们大多位于颅内，而脊髓脑膜瘤则较为罕见。大约10%的病例可见硬膜外成分，但单纯硬膜外脑膜瘤相当少见。然而，世界卫生组织二级（非典型）和三级（间变性）肿瘤可能具有侵袭性。我们报告了一例成年男性单纯硬膜外砂粒体型脑膜瘤累及胸椎的病例，尽管罕见，但硬膜外脊髓肿块的鉴别诊断应包括不常见的脑膜瘤。
