Spinal meningiomas account for 12% of all meningiomas and are usually located in the intradural extramedullary space. Among them, spinal metaplastic meningiomas are extremely rare. This is a case report on a 59-year-old man with thoracic spinal metaplastic meningioma. This male presented with progressively worsening right leg weakness, radiating pain and paresthesia. We present a rare case of pathologically confirmed metaplastic meningioma in the thoracic spine. Additionally, we review the pathological aspects and radiographic features of spinal metaplastic meningioma.

“…Approximately, 80% of spinal meningiomas are located in the thoracic spine, followed by cervical spine (15%), lumbar spine (3%), and near foramen magnum (2%). [ 1 2 3 ] Based on location, lumbar meningiomas constitute merely 2–3% of all spinal tumors. We hereby present a case of 55-year-old lady presenting with persistent low backache diagnosed to have intradural-extramedullary calcified metaplastic meningioma at L1 undergoing complete surgical excision of the lesion.…”

Cranial meningiomas may present with or without major deficits depending on their location and morphology. Spinal meningiomas account for 25% of all the spinal tumors. Most commonly encountered in the dorsal spine in middle-aged females, these intradural-extramedullary tumors can usually be excised without difficulty. Rarely, they can be encountered in the lumbar spine and may create many tactical problems for the surgical team especially if it is calcified and contains metaplastic bone. We report a 55-year-old patient who presented with backache and investigations revealed a calcified lesion at L1 level that was thought of as an ependymoma initially. Intraoperatively, the lesion was calcified in parts, and the histopathology revealed it to be a metaplastic meningioma with calcification. The patient had a transient hip weakness, which recovered completely later on. Calcification in meningiomas is common. However, frank bony metaplasia is extremely rare. More importantly, the applied aspect of their presence in the region of conus lies in the careful dissection to prevent damage to the surrounding neural structures. Awareness regarding the same may help us preventing complications in the future.

“…Observa-se uma clara tendência desses tumores de localizarem-se na região cervical, principalmente nos seguimentos mais altos, muitas vezes, inclusive, iniciando-se na região bulbo--medular. 2,5,[7][8][9][10] Os demais meningiomas espinhais, ao contrário, acometem, preferencialmente, a região torácica. 3,4 Encontramos apenas um relato de meningioma intramedular torácio.…”

“…Até o momento, encontramos cerca de oito trabalhos sobre meningiomas intramedulares cervicais descritos na literatura, todos estrangeiros. 1,2,[5][6][7][8][9][10] O presente estudo visa, portanto, relatar mais um caso na literatura mundial -talvez o primeiro relato de caso brasileiro -e revisar os demais estudos sobre o assunto publicados até o momento.…”

RESUMO IntroduçãoMeningiomas estão entre os tumores que mais acometem o canal espinal nos adultos. Cerca de 25% dos tumores do canal espinhal são meningiomas. Estima-se que 14% a 18,5% localizem-se na região cervical, 75% a 82%, na região torácica e 2% a 7%, na região lombar. 4 São, na sua quase totalidade, extramedulares.Os tumores intramedulares são mais raros, correspondem apenas a 5% dos tumores espinhais, sendo os astrocitomas e ependimomas reconhecidamente os mais frequentes nessa localização. 1 O acometimento intramedular do meningioma existe e, em qualquer seguimento, é extremamente raro, sendo descrito na literatura somente como "relato de caso". Até o momento, encontramos cerca de oito Arq Bras Neurocir 30(3): 142-5, 2011
