Spinal Epidural Atypical Meningioma: Case Report and Review of the Literature

Spinal atypical meningiomas are rare, and those whose main extension is in the epidural space are anecdotal. Here, we report a case of a young woman presenting with sensory disturbances and a radiological diagnosis of a dorsal epidural sleeve-like mass. The surgical resection of the lesion allowed the decompression of the spinal cord and led to the histopathological diagnosis of atypical meningioma. At the 3-month follow-up, her neurological recovery was complete. Because of the gross total removal of the lesion, adjuvant radiotherapy was not performed: At the 2-year follow-up, no recurrence of disease was detected. A comprehensive literature review was performed, and just two more case reports on epidural atypical meningiomas were found in the English literature. Through this case report and literature review, we described a rare manifestation of spinal meningioma that entered into a differential diagnosis for extradural spinal lesions, such as secondary malignancies.
