Metastatic renal cell carcinoma mimicking a meningioma

Single cerebral metastasis 3 and 19 years after primary renal cell carcinoma: case report and review of the literature

“…[4][5][6][7][8][9] Metastatic brain lesions in general are associated with a short life expectancy. Average reported survival periods after the diagnosis of brain metastasis range from 5 to 9.5 months; 14.3% to 43.2% of the patients survive the first year and much fewer than 10% live longer than 5 years after the diagnosis.…”

“…10 With brain metastasis from renal cell carcinoma only one patient has been reported to survive as long as 56 months so far. [4][5][6][7][8][9] There is no other report of a more than 16 year long asymptomatic survival after brain metastasis.…”

Ring-Enhanced Malignant Meningioma Mimicking a Brain Metastasis from a Renal Cell Carcinoma

“…Further, in this situation, we should have kept the information with a nuance on reflection until the histological diagnosis was confirmed. By contrast, brain metastasis mimicking a meningioma has been documented, and we should be aware of the possibility [6]. This case provided us instructive experience in handling a solitary brain lesion.…”

Solitary Brain Metastasis From Renal Cell Carcinoma 15 Years After Nephrectomy-Case Report-

“…2,3,[8][9][10][11]13,14,16,17,20,21,24) There are various mechanisms by which brain metastasis may develop after such a long period in the absence of other metastasis as follows. The first possibility is that microscopic brain metastasis occurs in the early stage, but the tumor grows slowly, so a considerable time elapses before the symptom appears.…”
