Giant-cell tumour involving the cranial vault: imaging and treatment

A giant-cell tumour involving the cranial vault was diagnosed in a 37-year- old man who presented with a large swelling at the vertex. The role of imag ing in the diagnosis and treatment of this tumour is described. On CT and M RI the appearances were nonspecific and the diagnosis was established by hi stological examination after removal of the tumour. A preoperative angiogra m showed a tumour blush and before surgery, embolisation was performed via the percutaneous and transarterial routes.
