Pant et al., report a case of extradural meningioma in a 50-year-old male located in the cervical spine that was surgically treated with the provisional diagnosis of a neurofibroma. Histopathological diagnosis of meningothelial meningioma was made with the routine hematoxylin and eosin (HE) stain. The origin, clinical course, radiological features, pathological findings with the differential diagnosis and surgical treatment are discussed based on a review of the literature. An extradural spinal meningioma, an extremely rare entity, is still a diagnostic dilemma on radiology as the radiologic findings overlap with many other common extradural spinal masses 1).
Bettaswamy et al., describe two cases of EDSM affecting the cervical spine and present their clinical profiles, radiological findings, operative management, and follow-up data, along with a review of the literature 2).
Benzagmout et al., report a case of spinal epidural meningioma diagnosed in an elderly woman complaining of right cervicobrachial pain of several years duration, associated with diffuse paresthesia and permanent numbness of her right index finger. The surgical removal of the tumor was incomplete because of the deep lateral extension of the lesion 3).
A 45-year-old woman presented with posterior cervicothoracic pain for 8 months following a motor vehicle crash. Magnetic resonance imaging of the cervical spine revealed an enhancing epidural mass. Computerized tomography of the chest, abdomen, and pelvis revealed no systemic disease. Due to the lesion's unusual signal characteristics and location, an open surgical biopsy was completed, which revealed a psammomatous meningioma. Surgical decompression of the spinal cord and nerve roots was then performed. The resection was subtotal due to the extension of the tumor around the vertebral artery 4).
