RESUMEN
Solitary fibrous tumor (SFT) is an unusual spindle cell neoplasm rarely described in the kidney. Usually occurring in the pleura, it has also been described in various extrapleural sites. We report a rare case of SFT of the kidney fortuitously found in a 55-year-old patient. The imaging features are illustrated. The definite diagnosis was made through histological and immunohistochemical study after radical nephrectomy.

We present the case of a 70-year-old patient presented to our institution for paresthesia of the right hemiface associated with dysarthria in aggravation since 1 year. He was diagnosed with right trigeminal melanoma metastasis. This case is characterized by a thickening of the right trigeminal nerve from his cisternal segment to his mandibular branch V3. MRI demonstrated an intensive perineural spread by a melanotic melanoma.
