WITHDRAWN: A rare case of primary intraosseous calvarial osteoblastic meningioma of the frontal bone in a young child

Abstract

Meningioma is a common intracranial neoplasm, accounting for 15–20% of all brain tumours. The “Primary Extradural Meningioma (PEM)” is an uncommon manifestation and a rare separate subset which arises outside the intracranial compartment, accounting for just 1–2% of all meningiomas. Primary calvarial intraosseous meningiomas comprise two thirds of these extradural meningiomas. They are usually seen in the 4th or 5th decades of life and have a predilection for females. We present a rare case of a very large Primary osteoblastic intradiploic calvarial meningioma in a young 11 year old male child, with a clinical and radiographic appearance simulating an Osteoma or Fibrous dysplasia. The findings on Radiographs, Computed Tomographic (CT) scans, Magnetic Resonance Imaging (MRI), the histological features and surgical treatment of this rare lesion are described.
