Solitary fibrous tumor of kidney is a rare mesenchymal cell tumor. It is an unusual spindle cell neoplasm identical to hemangiopericytoma. About 50 cases have been reported in the available literature so far. We present a case report of a 60 year old female who presented with urinary incontinence and swelling of lower limbs since 2 months.The CT scan showed a well defined, large 22x16x14.5cm sized, lobulated mass arising from upper pole of left kidney.She was operated upon and the mass excised. Histology and immunohistochemistry helped in arriving at a definite diagnosis of a solitary fibrous tumour. It is being reported due to its rarity of occurrence in the kidney.
