Background
Primary intra-diploic meningiomas are uncommon in childhood and, at the clinical onset, may be confused with other and more
frequent bone tumours because they lack specific clinical and radiological characteristics. Surgery is indicated not only
to remove the lesion but also to obtain an accurate histological diagnosis.
Case report
We report the case of a young girl who presented with a recently developed subcutaneous hard mass in the left pterional region.
Neuroradiological investigations revealed an intra-osseous lytic mass with a sclerotic reaction. Diagnosis was possible only
after the total removal of the tumour and its histological examination.
