| Abstract: | Childhood meningeal tumours are uncommon and mostly meningiomas. We reviewed the histological and radiological findings in
meningeal tumours in six children aged 12 years or less (four benign meningiomas, one malignant meningioma and one haemangiopericytoma).
Compared to the adult counterpart, childhood meningiomas showed atypical features: cysts, haemorrhage, aggressiveness and
unusual location. MRI features varied according to the site of the tumour, histology, haemorrhage, and presence of intra-
or peritumoral cysts. Diagnosis of the extra-axial tumour was relatively easy in two patients with meningiomas, one malignant
meningioma and one haemangiopericytoma. MRI findings strongly suggested an intra-axial tumour in two patients with benign
meningiomas, because of severe adjacent edema. Awareness of the variable findings of childhood meningiomas and similar tumours
may help in differentiation from brain tumours.
