Solitary Choroid Plexus Metastasis of Clear Cell Renal Carcinoma 11years after nephrectomy : A case report
Abstract Brain metastasis are the most commun intracranial tumours amongst adults. While brain metastasis of Renal cell carcinoma (RCC) are less commun, intraventricular localisation is particularly rare. There are few small series and mostly case reports which have noted intraventricular involvement of RCC metastasis. Here we report a new case of Solitary choroid plexus metastasis of clear cell renal carcinoma 11 years after nephrectomy.It’s about a 51-year-old patient, diagnosed with renal tumor in 2010 and a nephrectomy was performed. He presented with a frontal syndrome consecutive to a left frontal intraventricular tumor with ipsilateral ventricular dilation. He was operated on for a complete excision of this tumor. Histopathological examinations revealed a metastasis of clear cell renal carcinoma. He underwent 3 radiosurgery sessions one month later. At 6 months of follow-up, he has described an important clinical improvement, mainly of his frontal syndrome.BM secondary to RCC tend to be located in the ventricular system with close association to the choroid plexus. Early detection of brain metastases, and a therapeutic strategy including surgery and radiosurgery can offer patients an extended survival.
