Giant Skull Tumor: A Benign Meningioma

A 37-year-old male patient was complaining from painless forehead swelling, which started 5 years ago. Brain computed tomography scan and magnetic resonance imaging showed a large extradural mass compressing the both frontal lobes with skull bone infiltration, hyperostosis and enlargement. The patient was operated in 2 stages. In the first stage, the authors achieved separation for the tumor from the scalp and skull. In the second stage after 1 week, the authors continued with circumferential dural opening around the tumor and separation of the tumor from brain tissue. Duroplasty was performed by autologous fascia latta and skin flap was closed primarily. The specimen was received grossly as huge mass weighing 1530 g and measuring 39 × 16 × 12 cm. Histopathologic examination showed grade I meningioma extending beyond the skull to the surrounding soft tissue.
