“…Typical radiological characteristics of cystic spinal meningiomas are exceedingly similar to schwannomas, metastatic tumors, enterogenous cysts, and hydatid cysts. 6 However, conclusive result after surgery overthrew our prospective judgment. The pathological results also assured us that the cyst wall consisted of tumor cells.…”

Cystic spinal meningioma (CSM) is an uncommon meningioma variant. Extradural CSMs are particularly rare and difficult to distinguish from other intraaxial tumors. This study presents a case of a 36-year-old woman with intraspinal extradual CSM at the thoracolumbar spine. She experienced persistent weakness, progressive numbness, and sensory disturbance in the right lower limb. Magnetic resonance imaging (MRI) of the patient revealed an irregular cystic mass at the thoracic 11 to lumbar 3 levels dorsally. This case was misdiagnosed as other neoplasms prior to surgery because of the atypical radiographic features and location of the tumor.Extradural CSMs should be considered in the differential diagnosis of intraspinal extradural cystic neoplasms. Complete removal of cystic wall provides an optimal outcome, rendering the lesion curable.

“…With total excision of the tumor, recurrence-free survival rates of 93%, 80%, and 68% at 5, 10, and 15 years can be anticipated [10]. However, relatively poor outcomes are associated with subtotal resection, the presence of an extradural component, young age, multiple lesions, calciﬁcation, ossiﬁcation, and anterior location of the lesion [11]. The present case had an intradural component, single foci of intratumoral, and no sign of dural calciﬁcation and ossiﬁcation.…”

Highlights Thoracic spinal psammomatous meningioma is a rare subtype of meningioma often present with pain, sensory-motor deficit, and sphincter disturbance. Neglected spinal cord compression can result in a permanent neurological deficit. Surgical resection of the tumor relieved the spinal cord in a neglected case. The severe preoperative neurological deficit as a predictor of a poor prognosis. The neurological function after surgery hardly returns to the functional stage in a neglected case.

Extra-intradural Spinal Meningioma: A Case Report

2014

Extradural spinal meningiomas are uncommon, and their pathophysiology is not entirely understood. Here, we present the case of a 49-year-old woman with low back and left leg pain of 5 years duration. Magnetic resonance imaging revealed a mass, 1.8-cm in size, with rim enhancement in the spinal canal at the T12 level and extending into the left T12-L1 foramen. In the surgical field, the mass presented with the characteristics of an extra-intradural spinal meningioma. The patient underwent a T12 total laminectomy. A linear durotomy was performed at the midline, and the intradural portion was removed. The extradural portion was not separable from the adjacent dura and the left T12 root, and it was removed by dural excision. Pathological examination confirmed the diagnosis of psammomatous meningioma. We also conducted a literature review of similar cases. Based on our experience with this case, we believe that it is important to clearly distinguish extradural meningiomas from other types of tumors as misdiagnosis can change the operative plan. The long term prognosis of extradural meningiomas is not clear but total excision is thought to be essential.
