Primary intra-diploic meningioma in a child.

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.
