Thoracic spinal psammomatous meningioma is a rare subtype of meningioma. Among diverse types of mesenchymal differentiation, osseous metaplasia is found to be still rarer. We are presenting a new case of thoracic psammomatous spinal meningioma with osseous metaplasia in a middle aged female which that gives a sense of cancellous bone in the spinal canal. To conclude, meningiomas with osseous metaplasia are very rare tumors that complicate the surgical removal in certain cases. Ossification, if predicted prior to operation with computed tomography reconstruction, makes planning of removal easier. In our case, maintained cerebrospinal fluid spaces despite hard consistency of tumor made its removal easier once cerebrospinal fluid was drained. We have submitted this article because it is very rare and curable pathology and preoperative diagnosis helps in prevention of neurological injury during its excision.
胸椎沙粒体性脑膜瘤是脑膜瘤的一种罕见亚型。在各种间充质分化类型中，骨化生更为罕见。我们报告一例中年女性胸椎沙粒体性脊髓脑膜瘤合并骨化生的新病例，椎管内可见松质骨样表现。总之，伴有骨化生的脑膜瘤是非常罕见的肿瘤，在某些情况下会使手术切除复杂化。如果术前通过计算机断层扫描重建预测有骨化，将使切除计划更容易。在我们的病例中，尽管肿瘤质地坚硬，但脑脊液间隙得以保留，一旦引流脑脊液，肿瘤切除就更容易。我们提交这篇文章是因为它是一种非常罕见但可治愈的病理类型，术前诊断有助于预防切除过程中的神经损伤。
