Spinal Epidural En Plaque Meningioma Misdiagnosed as Lymphoma: A Case Report

ABSTRACT

Spinal meningiomas in the epidural location are rare, accounting only 2.5% to 3.5% of all spinal meningiomas. The diagnosis of spinal epidural meningiomas, solely based on imaging findings, can be difficult. They are easily mistaken for metastatic tumors or lymphomas, especially, meningiomas of the enplaque type. Misdiagnosis of meningiomas can affect the extent of surgery and patients' outcome; hence, a careful diagnosis is needed. We report a case of pathologically confirmed epidural enplaque meningioma in the cervical spine with neural foraminal extension. Additionally, its clinical implications, radiologic features, and diagnostic difficulties are discussed.
