BackgroundQuite a few cases of intramedullary meningioma have been described in previously reported studies. We have presented a rare case of intramedullary thoracic meningioma, which was quite different from subdural extramedullary meningioma, and the preliminary diagnosis was mistakenly given as hemangioblastoma.Case DescriptionA 46-year-old man with complaints of gait problems and pain in the right lower extremity was admitted to our hospital. The neurological examination revealed 3 of 5 motor strength, spastic paraparesis, hyperreflexia, increased tone, and sensory deficits in the right lower extremity. Contrast-enhanced images showed a T6-T7 intramedullary lesion and an evident and homogeneously enhanced lesion with clearly defined borders on the sagittal, coronal, and axial views. The preliminary diagnosis was hemangioblastoma. However, he underwent tumor resection, and the histopathological examination findings confirmed the diagnosis of intramedullary meningioma.ConclusionIntramedullary thoracic meningiomas are extremely rare and differ from the common subdural extramedullary meningiomas. Clinicians should be aware of this when diagnosing intramedullary tumors. Gross total resection using a microsurgical technique will be the best treatment strategy.Copyright © 2019 Elsevier Inc.
