Objective
The purpose of this study is to understand the epidemiology, clinical features, behavior, and the prognostic factors that influence the outcome of intracranial meningiomas in children.
Methods
Thirty-one patients with age less than 18 years who underwent surgery for intracranial meningiomas during the period of at 1988–2012 at Voluntary Health Services Hospital, Chennai, India were studied. These formed 3.7 % of the total 831 cases of intracranial meningiomas operated at the institute.
Results
The study group included 22 (71 %) males and 9 (29 %) females. The mean age of presentation was 15 years, with the youngest being 9 months old. Two (6 %) had evidence of neurofibromatosis type 2 (NF2). The most common symptoms at presentation were seizures in 11 (35.5 %), weakness of limbs in 11 (35.5 %), and raised intracranial pressure in 10 (32 %). Convexity meningiomas were seen in 16 (51 %) and skull base in 15(49 %). Multiple meningiomas was seen in two (6 %) of the patients and intraventricular location was found in one patient (3 %). Two (6 %) had evidence of NF2. Gross total excision was achieved in 26 (83 %) and subtotal excision in 5 (17 %). WHO grade I was found in 20 (64 %) and higher grade was seen in 11 (36 %). The mean follow-up was 46.2 months. Recurrence was seen in 20 patients (64 %). In patients with higher grade or with recurrence resurgery and radiotherapy was given. Three (9 %) had multiple recurrences. On a mean follow-up of 46.2 months, 25 patients (81 %) were neurologically intact, 5 (16 %) were having moderated disability, and 1 (3 %) patient died.
Conclusions
Childhood meningiomas are uncommon lesions with a slight male predominance. They can have a varied clinical presentation. Higher grade is found more frequently compared with adults. Gross total resection is the goal and in higher grade meningiomas radiotherapy helps as a good adjuvant. Though the rate of recurrence is high, resurgery and radiotherapy gives a good outcome.
