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.
