Brain meningioma invading and destructing the skull bone: replacement of the missing bone in vivo.

BACKGROUND: Meningiomas are frequently encountered tumours. In those invading locally into the adjacent tissue, reconstructions may pose a problem.

CASE REPORT: We report a case of a benign convexity brain meningioma with invasion into the skull bone and subcutaneous tissue. The tumour was removed completely, together with the infiltrated tissue and the defects were successfully closed with in vivo bone reconstruction.

CONCLUSIONS: The reconstruction of the skull bone is sometimes needed after the benign meningioma excision. Artificial bone may be a suitable material, allowing fast intraoperative reconstruction with excellent brain protection and cosmetic effect during the one-stage procedure.
