“…Ossification of spinal meningiomas is attributed to metaplasia of the arachnoid. [ 21 ] Estrogen deficiency is also suspected to intensify the calcification/ossification of meningiomas where there are necrotic fibroblasts and an elevated number of collagen fibrils. [ 21 ]…”

“…[ 27 ] The resection of the involved adjacent dura warrants duroplasty, which increases the complexity of the procedure. [ 1 , 21 , 27 ] Perhaps, a complete ossification, firmness of the tumor, and size can increase surgical morbidity because of difficulty to manipulate the tumor without compressing the spinal cord. In some cases, GTR is unsafe because of an absent distinct plane between the tumor and the spinal cord.…”

Background: The incidence of spinal meningiomas is 0.33/100000 population, and ossified spinal meningiomas are even less commonly encountered. Case Description: A 64-year-old male presented with a progressive T4-level thoracic myelopathy. MR imaging revealed an intradural extramedullary mass that significantly compressed the spinal cord. The accompanying CT demonstrated hyperdensities within the lesion consistent with punctate calcification vs. ossification (i.e. consistent with histological bone formations within tumor). The patient underwent complete resection of the tumor resulting in a full recovery of neurological function within 6 postoperative weeks. The pathological specimen showed findings consistent with an ossified spinal meningioma. Conclusion: Here, we identified a rare case of an ossified thoracic T4 meningioma occurring in a 64-year-old male.

“…Several case studies of meningioma with calcification had shown clinical improvements after tumor removal with [13], [14] or without en bloc resection method. [4], [15] In this case, the tumor was successfully resected with total tumor resection, both solid (calcified) tumor and soft tumor using laminectomy method and tumor resection with a posterior approach, with a satisfactory final result in improved clinical symptoms and quality of life.…”

Abstract Introduction: Intradural extramedullary (IDEM) tumors are benign neoplasms arising in the spinal canal about two-thirds of primary spinal tumors and 15% of tumors affecting the Central Nervous System. Spinal en-plaque meningioma is a type that grows in a sheet-like or collar-like, and incidence in the literature only ranging from 0.1% to 3.1%. Pain is the most clinical symptom, weakness and sensory changes also occur frequently. Magnetic resonance imaging (MRI) is the standard modality for the radiologic diagnosis of meningioma. Case Report: A patient, 35 years old man with a diagnosis of intradural extramedullary spinal meningioma (IDEM) en-plaque with calcification, confirmed by the symptoms, workups such as spinal MRI, and intra-operative findings. The patient was successfully treated surgically with laminectomy and total tumor resection with a posterior approach. Discussion: Spinal en-plaque meningioma is a type that grows in a sheet-like or collar-like manner around the spinal cord can involve dura extensively with significant neurological deficits. Patient was with lower limb weakness, and had a history of back pain radiating to the right limb for the last 1 year. Spinal meningiomas are primarily found in the Intradural Extramedullary, and the tumor diagnosis is typically fairly straight forward based on radiologic findings. Meningiomas are most commonly found in the thoracic region of the spine. In this case from MRI Imaging was revealed a mass in thoracic region of the spine pressing the spinal cord anteriorly. The management of spinal en-plaque meningioma is tumor resection surgery. A retrospective study suggested a significant improvement in neurological deficit post-tumor resection on patients with spinal IDEM tumor. Conclusion: Spinal meningioma is a reasonably frequently found case of a spinal tumor but spinal en-plaque meningiomas are rarely found. MRI scan is the radiological gold standar diagnose spinal en-plaque meningiomas. Patient was successfully treated by total tumor resection using the laminectomy method and tumor resection with a posterior approach without any postoperative complications observed.
