Object: The purpose of this retrospective study is to determine the clinical characteristics and the prognosis of the spinal meningioma in childhood (under 18 years of age) based on the treatment at our institution.
Methods: Ten spinal meningioma cases in children were treated during the last 9 years. The clinical data was retrospectively analyzed and the results were compared with those in the literature.
Results: The series included eight males and two females and the mean age was 13.2 years. The most common initial symptoms were pain (6/10) and the common signs were limb weakness (4/10) and gait disturbance (2/10) and distal paresthesia (1/10) and bladder disturbance (1/10). Four patients had other clinical signs of neurofibromatosis type II (NF-2) such as tumors elsewhere. All the tumors were located in cervical and thoracic vertebrae. Resection according to Simpson Grade I (6/10), II (2/10), III (1/10), and IV (1/10) were performed. Grade II meningiomas accounted for 3/10 in this series. All patients were followed up with mean follow-up period of 43 months. Seven patients had recurrence of the tumor in that period and one had died.
Conclusions: Spinal meningioma is an uncommon pediatric neoplasm and has a poor prognosis. It has a male predominance and is inclined to be associated with NF-2, and those that are associated with higher pathologic subtypes and NF-2 have more unfavorable outcome. Every effort should be made to achieve total removal which may decrease the incidence of recurrence.
