Intradural Spinal Meningioma in a 20-Month-Old Female

Abstract

Meningiomas in children account for less than 2% of all meningiomas, and their location in the spinal region is even less common. The authors present a case of a 20-month-old female who presented with lumbar back pain, neurogenic bladder and progressive paraparesis 6 months after she started to walk. Magnetic resonance imaging demonstrated an intradural extramedullary neoplasm extending from the tenth thoracic vertebra to the third lumbar vertebra. Complete excision of the tumor was performed by means of laminoplasty and the patient had a satisfactory postoperative recovery. Pathology and immunohistochemical studies diagnosed psammomatous meningioma.

Spinal Clear Cell Meningioma in a 3-Year-Old: A Case Report

“…This entity has been described as the most common subtype in pediatric spinal meningiomas [2,3,4,5,6]. It is reported to occur more in the lumbar region affecting the cauda equina [2,3,4,11] compared with other variants of meningiomas that occur in the thoracic and cervical regions [13,14,15,16]. The average age in children from case reports with literature review is about 11 years [11], with the youngest reported patient being a 2-month-old child [2].…”

Extradural Nodular Fasciitis Arising in the Spinal Canal

“…10 Morphologic features, such as a biphasic pattern (cellular Antoni A area and hypocellular Antoni B area) in schwannoma and whorl formation and psammoma bodies in meningioma, are helpful for the differential diagnosis; however, immunohistochemical examinations are essential for making a correct diagnosis. 11 Schwannoma is invariably S-100 protein positive and meningioma is epithelial membrane antigen positive, whereas both markers are absent in nodular fasciitis.…”
