BADEMCI, G.; BOZDOGAN, O.; BERDAN, F.  and  EVLIYAOGLU, C.. Extremely delayed renal cell carcinoma metastasis mimicking convexity meningioma. Neurocirugía [online]. 2008, vol.19, n.6, pp.562-564. ISSN 1130-1473.

Cerebral extra-axial metastasis mimicking meningioma which satisfy several criteria for a diagnosis of meningioma, but which have proved instead to be metastatic carcinoma and extremely delayed cerebral metastasis from renal cell carcinoma form the focus of the presentation. 68-year-old-woman who had been operated for renal cell carcinoma 20 years previously is presented with new symptoms of intracranial mass. A large extraaxial mass of the convexity which destroyed calvarium and dura was excised with Simpson Grade I removal, revealed metastatic carcinoma. Imaging characteristics can not always discern between meningioma and metastatic tumours. A meticulous clinical evaluation and histopathological diagnosis is essential in patients with intracranial mass even they resemble both primary and metastatic tumours.
