title: Isolated brain metastasis from a small renal mass.
abstract: The identification of small renal masses is increasing. Active surveillance is a guideline-approved management strategy for select patients with small renal masses. Metastases during the observation of small renal masses are uncommon, and no cases of brain metastasis have been reported. We report the case of a 73-year-old man who presented with tonic-clonic seizures as the result of a brain metastasis from a small renal mass (3.5 cm in maximal dimension). Treatment with whole brain radiotherapy was undertaken successfully. The patient will undergo surveillance with consideration for systemic therapy at the time of progression.
