Brain Metastasis of Wilms Tumor in Adult.

Abstract

Wilms tumor is a rare renal tumor in adults. To the best of our knowledge, only a small number of cases of brain metastasis have been reported in the literature. We report the case of a 29-year-old female with headache and dizziness, with a parietal mass and pathologic diagnosis of Wilms tumor metastasis. The patient was admitted with a 3-month history of lumbar pain and 2 months of progressive headache associated with dizziness. Abdomen magnetic resonance imaging showed a renal mass. Post nephrectomy, the neurologic signs worsened and a head magnetic resonance imaging presented in the right parietal lobe, convexity, heterogeneous lesion with little perilesional edema. The patient underwent a complete surgical resection with success. The adjuvant treatment was chemotherapy. Few cases of brain metastasis of Wilms tumor exist in the literature. Surgical management is considered in cases with intracranial hypertension or focal signs. The adjuvant treatment options are immunotherapy and chemotherapy.
