Extremely delayed renal cell carcinoma metastasis mimicking convexity meningioma.
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 extra-axial 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 when they resemble both primary and metastatic tumours.
